The time entered in P8‐19 must be sufficient for the PID feedback signal from the system output sensor to settle to a steady level. • If the duty run times between DOL slave pumps are to be balanced then the maximum permissible difference in hours should be entered in P8‐16. 13.2. Pump Staging – Multiple Drive Cascade Summary: The below illustration shows the use of a Optidrive HVAC units as the controllers in a variable speed pump staging system. All pumps in this configuration are controlled the Optidrive HVAC units in variable speed mode with co‐ordination and communication carried out over the built in RS485 communications link as shown below. Drives can be connected using the RJ45 data cables and the RS485 Data Cable Splitter as shown above up to a maximum of 5 drives. Part numbers are as follows: ...
Optidrive ODV‐2 User Guide Revision 1.00 In addition, the value of P8‐15 on the network master, ‘Pump staging DOL pump availability’ must be set with the number of additional drives available in the system (slave drives), excluding the master (set to a value other than 0). The master drive must be set to drive address 1 (default), with the addresses of the slave drives set in sequence to subsequent addresses (2. 3. 4. 5...). Addresses are set within P5‐01. When the system is enabled the master drive will check the run time clocks for all drives in the network which are stored and maintained within menu 0 of the master drive. The first available drive with the lowest run time is automatically run first. At a predefined level additional ...

Parameter Number Parameter Description Terminal Value set P2‐15 Relay output 1 function select 14 / 15 10 P2‐18 Relay output 2 function select 16 / 17 / 18 10 When the maintenance interval has expired and the scheduled service has been completed the service interval timer is reset by setting P6‐25 = 1, Reset Service Indicator. The timer for the next service interval starts from the point at which the previous indication was reset. Advanced security access is required (default P1‐14 = 201) in order to access the Reset Service Indicator parameter. Quick Setup Overview: Maintenance Interval Set‐up • Set Parameter P1‐14 = 201 to allow access to advanced parameters in menu 6 • Set the number of hours between services in parameter P6‐24, Service Timer Interval (Default 5000). • If a drive output is required to indicate that maintenance is due then configure the output based on the table above (P2‐15 or P2‐18 = 10). Maintenance Interval Reset • Set Parameter P1‐14 = 201 to allow access to advanced parameters in menu 6 • Set parameter P6‐25 = 1, Reset Service Indicator to reset the Maintenance Timer Interval. 13.4. Load Profile Monitoring Function The Load Profile Monitoring Function provides under and over torque protection to the driven load. Practical applications for the function might include Belt Snap detection, Motor Stall detection, Pump Blockage, or Pump Dry Run protection. ...
Optidrive ODV‐2 User Guide Revision 1.00 Maximum Frequency / Speed parameter (P1‐01) and Minimum Frequency / Speed parameter (P1‐02) can be adjusted following execution of the automatic measurement sequence without affecting the results obtained during the automatic measurement sequence. When operating outside of the maximum and minimum speed range the function is disabled. When setting parameter P8‐06 to activate the Load Profile Monitoring Function a value is set that instructions the Optidrive HVAC unit to trip on detection of under‐current (P8‐06=1), over‐current (P8‐06=2), or combination of both under‐current or over‐current (P8‐06=3). A detection tolerance for the Load Profile Monitoring Function is set within parameter P8‐07. Parameter P8‐07 (Load Profile Monitoring Function Bandwidth) is set as a current (amps) value and is then applied to the standard operating profile stored within the drive to allow for acceptable variations in the motor current measurement. The value entered is applied symmetrically to the nominal current value so totally bandwidth is 2 x P8‐07. In addition to a bandwidth of tolerance being applied to the standard operating profile (P8‐07) a trip delay or time limit can also be specified for operation on the drive within the over torque or under torque regions. This time is set within parameter P8‐08 (Load Profile Monitoring Function Trip Delay). This parameter can be set to avoid nuisance tripping whilst the load is in a temporary or transitional state. The Optidrive HVAC will trip immediately on detecting an under / over torque condition for a time period greater than that set in P8‐08 and will disable output to the motor with coast to stop. The trip will be displayed on the OLED display and can be reset by pressing the Keypad STOP key. The Optidrive HVAC can be set to run an automatic pump cleaning function once the Load Profile Monitoring Function has detected an over‐ torque condition. See section 13.5, Pump Clean Function for more information. O_torq : Over‐Torque Level Detected resulting in drive trip (Fault code 24) Trip Codes: ...

Optidrive ODV‐2 User Guide Revision 1.00 If a digital input is assigned to this function then it will activate the pump clean sequence regardless of the setting of parameter P8‐03 (Pump Cleaning Function Configuration). When the Pump Clean Function is initiated via an input to the drive, the drive will ramp immediately from its current operation speed to the first speed defined by the pump clean cycle using applicable ramp rates. The digital input assignment for the pump cleaning function is defined through P9‐42 – Clean trigger input edge. Menu 9 can only be accessed using the advanced level security access (default P1‐14 – 201). Set P9‐42 with the value associated with the digital input to be used. The Pump Cleaning cycle is defined by setting two segment speeds, a ramp time (used for acceleration and deceleration), and a segment time in the following parameters: Parameter Number Description P2‐05 Clean Speed 1 P2‐06 Clean Speed 2 P8‐04 Pump Cleaning Function Time Interval P8‐05 Pump Cleaning Function Ramp Time If either of the two Pump Cleaning Speeds are set to zero then that segment of the cleaning cycle is disabled. Pump cleaning speeds can be set with positive or negative values to allow forward or reverse motion to be performed and two stage or bidirectional profiles to be created. The Acceleration ramp for the pump clean function is determined by setting P8‐05. The deceleration ramp rate is determined by the standard deceleration ramp parameter P1‐04. ...
Optidrive ODV‐2 User Guide Revision 1.00 13.6. Pump Stir Function The Pump Stir function is used to trigger the pump to run following a period of inactivity. When the motor has remained inoperable for a pre‐ defined time a user defined motion profile is carried out on the pump. The function is active when the drive is in PID mode and the timer activated by the drive entering into ‘standby’. The function is used to prevent pump blockage or pump degradation caused by sustained periods of pump inactivity. The function might also be used for fan applications to prevent degradation of bearing lubricants. ...

Optidrive ODV‐2 User Guide Revision 1.00 The main selector switch selects between the following modes. • System Off : Drive is powered off; Bypass contactor is off • Bypass Control : Drive is powered off; Bypass contactor is on, motor running from bypass supply • Drive Control : Drive is powered on; Bypass or Drive Output contactor selection is controlled by the drive When the Main Selector Switch is set to Drive Control, the drive input contactor is switched in such that the drive will power up. Selection of the two motor output contactors is controlled by the drive dependent on the settings provided to the drive by the user. When Optidrive HVAC control is selected the drive can co‐ordinate bypass or drive control based on the settings and running conditions of the drive. The two drive control relays (relay 1 and relay 2) are automatically configured when Bypass Mode is enabled. Relay 1 is configured for bypass control and is connected directly to the Bypass contactor. Relay 2 is configured for drive control and is connected directly to the Drive Output Contactor. Under normal operation the drive will close relay 2, bringing in the Drive Output contactor, and operation of the motor will be as per the logic and speed reference configuration of the drive. The drive will switch off the Drive Output contactor (relay 2) and switch in the Bypass contactor (relay 1) if one of the bypass control functions is enabled and the logic to trigger that function becomes true. Bypass control functions include: • Drive will switch to bypass if a trip condition prevents the drive from operating the Bypass on Fault motor • Drive will switch to bypass if the Fire Mode function is assigned to a digital input and Bypass on Fire Mode that input becomes true (can be open active or close active) • Drive will switch to bypass if a digital input is assigned to bypass control (through Bypass on Input menu 9) and that input becomes true. Note: A combination of bypass conditions is permitted. ...
Optidrive ODV‐2 User Guide Revision 1.00 Bypass on Fault. Bypass Mode on Fault is enabled by setting parameter P8‐11=1 (enabled). Once enabled the drive will switch to bypass mode in the event of a trip or fault occurring on the drive. When a trip occurs the drive will immediately open the drive output contactor (drive output already disabled due to trip), wait a time (defined by P8‐13) and then close the bypass contactor. The motor will remain under Bypass control until the enable/run input is removed from the drive (drive control terminal 2) at which point the Bypass contactor will be opened. When the run/enable input is closed again the drive will attempt to run under drive control (drive output contactor closed). ...

Optidrive ODV‐2 User Guide Revision 1.00 • P1‐13 : Fire Mode can automatically be configured on digital input 2 by selecting values 4, 8, or 13 in parameter P1‐13. (see section 8.1 – Digital input configuration parameter. • P9‐32 : Fire Mode input source can be set via P9‐32 to an available digital input. Advanced level security (default P1‐14 = 201) is required to access menu 9 parameters The fire mode function is enabled once an input is assigned to activate fire mode. The logic selection for the fire mode input is configured through parameter P8‐09 – Fire Mode Logic Select. It can be set to open active (0) or close active (1). The default setting is open active such that the loss of the input signal to the digital input will cause the fire mode function to activate. The speed of operation of the Optidrive HVAC whilst in fire mode is defined by parameter P8‐10 – Fire Mode Speed. This can be set to any value up to maximum speed (P1‐01) in either the forward or reverse direction. When an input is configured to trigger Fire Mode and that input is activated all other inputs to the drive are ignored. Other inputs to the drive only become active again once the Fire Mode input is removed. ...
Optidrive ODV‐2 User Guide Revision 1.00 • Set parameter P1‐13 to a value that activates Fire Mode selection on digital input 2 (4, 8, or 13). Or • Set parameter P9‐32 to an available digital input value. Note, P1‐13 must be set to 0. Any other digital inputs required must also be configured through menu 9. • If required, set either P2‐15 or P2‐18 = 9 to configure output relay 1 or output relay 2 to indicate fire mode active. 13.9. Motor Pre‐Heat Function and DC Injection The Optidrive HVAC can be set to inject DC voltage into the motor on a start or stop condition, or can be set to maintain magnetising voltage across the motor whilst the speed reference to the drive is set to zero. Applying voltage to the motor creates a circulating current in the motor windings which in turn heats the motor and prevent moisture forming on the surface of the motor. Formation of moisture on the motor might be due to the motor operating in humid conditions or in low ambient temperature, or motor temperature change (specifically cool down) causing condensation to form. Operational Overview: Setting up DC Injection braking on Start or Stop The function uses the DC Injection parameters on either starting or stopping the motor in order to create a current and maintain an appropriate temperature within the motor prior to starting or post stopping. Parameters for configuring the DC Injection are contained in menu 6. Access to level 6 requires advanced level security access (Default P1‐14=201). The level of DC Injection Voltage applied to the motor is ...
Page 49
Optidrive ODV‐2 User Guide Revision 1.00 The function uses the Boost Voltage on the drive reaching zero speed in order to create a current and maintain an appropriate temperature within the motor. The drive Standby Mode must be disabled so that the drive output is not automatically put into Standby following a period of operation with zero speed reference. The level of DC Injection Voltage applied to the motor is set in parameter P1‐11 (V/F Boost Voltage). The current can be monitored by changing the OLED display to show Amps (cycle the display to show Amps by pressing the Navigate button). Caution: Always confirm the maximum acceptable current level that can be applied to the stationary motor prior to configuring the voltage Boost function. It may be necessary to contact the motor manufacturer to confirm acceptable levels for operation. Check operation of the drive to ensure current levels are within the specified limited. The time set in the Standby Mode parameter (P2‐27) must be 0. This will disable Standby Mode and ensure Boost Voltage is applied whilst the drive is enabled with zero speed reference. Ramp to Stop should be enabled (P1‐05=0) and appropriate ramp rates set in P1‐03 and P1‐04. If an input is required to activate motor stop with voltage boost then a digital input can be set to Preset Speed 1 (see section 8.1) and the Preset Speed 1 value (P2‐01) set to 0Hz. Quick Setup Overview: Setting up DC Injection braking on zero speed reference • Set Basic parameters P1‐01 to P1‐10. • Ensure P1‐05 is set to 0, Ramp to Stop. Ensure appropriate ramp rates are set in P1‐03 and P1‐04. • Set Parameter P1‐14 = 101 to allow access to advanced parameters in menu 2 • Set parameter P2‐27 = 0 to disable drive Standby Mode (default) • If a digital input is required to activate motor stop with V/F Boost Voltage then ensure P1‐13 is set to 1 (default). Digital input 2 (control terminal 3) is now configured for this function. Ensure P2‐01 = 0. • Set the Boost Voltage to apply in P1‐11. • Monitor current levels on the drive display and motor temperature to ensure they remain within the motor manufacturers specified limits. ...
Optidrive ODV‐2 User Guide Revision 1.00 14. PID Control Applications 14.1. Overview The PID Controller is a mathematical function designed to automate adjustments within a system and to eliminate the need for the machine operator to continuously pay attention to machine operation and to make manual adjustments. For a drive this generally means adjusting the motor speed automatically to try and maintain a specific measured value from a measurement sensor in the system, with the set‐point being provided directly to the drive. For example, when the Optidrive HVAC is controlling a pump it might be required to maintain a pressure which is proportional to the speed the drive runs the motor. The required pressure (known as the set‐point) is provided to the drive. The measurement sensor is connected to the drive analog input and provides a measurement (known as the feedback) of the current system pressure. The PID function in the drive compares the set‐point and feedback and changes motor speed in order to increase or decrease the feedback to match the set‐point. Should the set‐point change then the drive will react by again changing motor speed is order to match the feedback signal to the new set‐point value. The difference between the set‐point and feedback signals in real time is known as the PID error. PID represents P ‐Proportional, I ‐ Integral, D – Derivative and describes the three basic mathematical functions applied to the error signal, using the calculated sum as the reference for controlling the motor speed. By adjusting values associated with the P, I, and D functions the programmer can configure how dynamically the drive responds to the PID error and how stable the system output (motor speed) is able to be maintained. Achieving best possible dynamic response and maintaining system stability by adjusting the values used by the P, I, and D functions is known as ‘tuning the PID control’. Caution: Adjusting values for the PID controller can result in dynamic response from the motor or introduce instability into the motor speed control. Tuning of the PID controller should only be attempted by experienced engineers. ...
Page 51
Optidrive ODV‐2 User Guide Revision 1.00 14.2.3. PID Operating Mode Selection For default operation the drive response to an increase in feedback signal is to decrease motor speed and vice versa to adjust the feedback signal back to the set‐point. This is referred to as ‘Direct Mode’ PID control. For example when pressure increases in a pumping system and the feedback signal increases then the drive response is to slow the pump to reduce the pressure. This mode of operation is the default drive behaviour and can be selected by setting P3‐04=0 (User PID operating mode = Direct Mode). The alternative operating mode is when an increase in feedback signal requires an increase in motor speed. This is referred to as ‘Inverse mode’ PID control. For example on a condenser fan control where the feedback signal increases with the load on the condenser increases and the fan is reduced to operate at a higher speed. This mode of operation can be selected by setting P3‐04=1 (User PID operating mode = Inverse mode). PID operating mode selection is summarised in the following table. Parameter P3‐04 Setting Mode Selected Feedback Behaviour Motor Behaviour 0 Direct Mode Signal Increases Speed decreases Signal decreases Speed increases 1 Inverse Mode Signal Increases Speed increases Signal decreases Speed decreases 14.2.4. PID Controller Output Limits The output from the PID controller can be limited by settings within the drive unassociated with the maximum and minimum speed limits set in drive parameters P1‐01 and P1‐02. This means that different maximum and minimum values can be applied when the drive switches from PID control to a preset speed (via digital input) or variable limits can be applied. Parameter P3‐09 – PID Output Limit Control sets the method used for determining the PID output limits. The following options are available. Parameter P3‐09 Description 0 Digital preset limit value (P3‐07 and P3‐08) will be used to limit PID controller output ...
Page 52
Optidrive ODV‐2 User Guide Revision 1.00 point). For dynamic systems which respond quickly, the value will need to be shorter. Slow response systems, such as temperature control applications will require a correspondingly longer time setting. P3‐03 Differential Time Constant: Range 0.00 to 1.00, Default 0.00 The differential time constant is also a time based function, this time modifying the PID output based on changes in the Set‐point. In most applications, leaving the setting of P3‐03 at zero will give good results. The user has to adjust the PID control parameters (P‐gain, I‐gain and D‐gain) in P3‐01, P3‐02 and P3‐03 respectively to get the best control performance. The values will vary dependent on system inertia and the time constant (rate of change) of the system being controlled. 14.2.7. PID Sleep and Wake Functions The Optidrive HVAC can be programmed to disable its output when running in PID mode when the speed output to the motor falls below a programmed value. This is referred to a Sleep or standby mode. Generally fan and pump applications perform little useful work at the lower end of the speed range and the sleep function allows the drive to save energy during periods of low system efficiency by shutting off the output to the motor. The level for sleep mode is programmed in parameter P3‐14. A time period is also applied to the sleep function such that the sleep function must remain below the value set in P3‐14 for the period programmed in P2‐27 (standby mode timer) before the sleep function is activated. Sleep mode is disabled if P2‐27 = 0. Once the Optidrive HVAC enters into sleep mode a separate wake up mode can be applied for the drive. The wake mode level is used to trigger the drive returning out of sleep mode to normal operation. Setting different thresholds for the sleep and wake levels allows boundaries to be set that stop the drive continuous entering in and out of sleep mode and the settings to be optimised to maximise efficiency. Wake up level is set in parameter P3‐13 – PID feedback wake up level and is set as a percentage of the feedback signal such that when the feedback signal reaches a specified level the drive is triggered out of sleep mode and the PID controller re‐enabled. 14.2.8. PID Boost Cycle on Sleep and Wake The Optidrive HVAC can be programmed to execute a pre‐defined boost cycle on entering or exiting sleep mode. This feature could be used to boost pump pressure prior to drive entering sleep mode so the drive is able to maintain sleep mode status for a greater period (prevent frequent switching in and out of switch mode. The boost on wake could be used to execute a cycle that quickly returns the system to normal ...
Optidrive ODV‐2 User Guide Revision 1.00 The execution time for both the sleep and wake boost functions (P6‐11 and P6‐12) include the time taken to accelerate to the boost speed (P2‐ 07 and P2‐08) but not the time to accelerate or decelerate once the boost function ends. This is shown in the timing diagrams. When boost on sleep in activated the Optidrive HVAC will automatically run the boost on sleep function whenever the drive is stopped / disabled. When boost on wake is activated the boost on wake function is automatically run whenever the drive is started / enabled. 14.3.
