1 1 1 1 General Description The Elite® Pro Series of D.C. motor controls provide microprocessor control of speed and torque control of 5-600HP D.C. motors rated for NEMA type "C" power supplies. The EPN series for non- regenerative applications and the EPR regenerative series are offered in compact panel mounted assemblies.
Excess ambient temperatures within enclosures can reduce the life expectancy of electronic components and cause heatsink Over-Temperature fault on the Elite Pro control. Contact Carotron for assistance in sizing enclosures for particular horsepower ratings.
the possibility of accidental grounding. Signal level wiring such as listed above should be routed separately from high level wiring such as armature, field, operator control and relay control wiring. When these two types of wire must cross, they should cross at right angles to each other. Any relays, contactors, starters, solenoids or electro-mechanical devices located in close proximity to or on the same line supply as the motor control should have a transient suppression device such as an MOV or R-C snubber connected in parallel with its coil.
Carotron recommends the use of three phase DIT, drive isolation type transformers. While Elite Pro controls do not require these transformers for proper operation, they can be helpful in reducing the effects of line transients on this control and generated by this control on other products and can provide fault current limiting in the event of severe motor or control failure.
In some cases, the field voltage required by a motor exceeds the maximum obtainable field voltage that can be derived with the required AC line voltage for the motor armature. In these cases, an external single phase AC supply for the field bridge must be used. The supply connects to FL1 and FL2 and must be in phase with the armature supplies L1 and L2.
5 5 5 5 Human Machine Interface (HMI) 5.1 Description of Interface The Human Machine Interface (HMI) is the primary method for accessing the drive parameters. It allows custom user configuration, monitoring, and troubleshooting. The HMI consists of a 4 line by 20 characters display.

core diameter Core (446) × maximum diameter 6.5.3 (Note: This step can be skipped if Diameter Select (442) is set to External Diameter Ratio). With an empty core loaded on the winder, start the line and run at full line speed.
2. The Current Proportional Gain (107), Current Integral Time (108), Velocity Proportional Gain (201), and Velocity Integral Time (202) parameters are preset by Carotron to provide stable and responsive performance under most load conditions. When required, the drive performance can be optimized for a particular application or to correct undesirable operation by use of these adjustments.
Figure 5 Velocity Loop In order to adjust properly, connect an oscilloscope to Analog Output 1 Terminal 21 (Velocity Feedback). Using the HMI, temporarily set the Ramp Bypass (305) parameter to True. Run the drive and apply a step change to the external speed reference. Observe the response to the drive.
otherwise changes will be lost after a drive reset or power loss. Whenever the user exits the Programming section, the drive will prompt you to save parameters. The Save command is also accessible in the Setup|Programming|Misc Parameters|System section and the Quick Programming Menu 15 (QP15).
7.2 Setpoints Block The Setpoints block selects between multiple references. Figure 9 Reference n (217-220) Internal references 0-3 are 4 independently adjustable references that can be used in the Run mode. Analog Input 1 is factory preset to Reference 0. Jog Reference (221) Internal reference that is used in the Jog mode.
7.3 Setpoint Sum Block The Setpoint Sum Block sums 4 different references to obtain the Velocity Demand. Figure 10 Setpoint A Ratio (498) Allows scaling of the Ramp Output signal before being summed with Setpoints B & C. Setpoing D (499) This parameter differs from Setpoints B &...

Jog Delay (246) This adjustment serves to extend the mechanical life of the armature contactor by reducing the number of mechanical operations in an application where a high rate of repeat "jogging" is performed. When the Jog button is pressed and then released, the reference is immediately clamped to stop the motor but the contactor is held energized for up to ten seconds.
Drive Status Elite Pro Mode Stop Ramping to Stop (from Run) Ramping to Stop (from Jog) Jog Delay Quick Stop Coast Stop Emergency Stop Table 7: Drive Status 7.5 Zero Speed Logic Block Figure 12 Zero Speed Setpoint (207) The Zero Speed Setpoint parameter sets the Zero Speed threshold. This level determines the speed at which the control loops are clamped and the armature contactor is de-energized after a Stop command has been given to the drive.
Loop Enable (212, Read-Only) The Loop Enable parameter determines if the Velocity and Control Loops are active. Loop Enable is controlled by the Standstill Logic and Ramp Enable. 7.6 Velocity Loop Block The Velocity Loop uses a closed loop Proportional-Integral (PI) loop to maintain desired speed. The Loop Enable output from the Zero Speed Logic Block determines when the PI loop is active.
no other feedback device such as a tachometer or encoder is used. Even if another feedback device is used, Feedback Select should be set to AFB initially to verify proper operation of the external feedback device. The IR Comp signal sums with the AFB signal to become the Velocity Feedback.
Velocity Integral Time (202, 326) The Velocity Integral Time adjustment eliminates steady-state error. Decreasing the integral time improves the response of the drive. However, setting it too low can cause oscillation. The adjustment is in seconds and corresponds to the amount of time that the signal would take to integrate from 0 to maximum with 100% Velocity Error.
Drive Mode (109, 110) The two mode select parameters determine the operating mode of the drive. Parameter 109 in the Most Significant Bit (MSB) and parameter 110 is the Least Significant Bit (LSB). The Toggle softkey on the keypad scrolls through each of the selections. Mode Velocity Torque...

version of this signal is also provided (113). Current Feedback (IFB, 102, filtered-112, Read-Only) The Current Feedback is derived from two of the three incoming AC lines and is used by the PI loop to regulate the amount of armature current in the motor. The signal is also used to provide IR Compensation to the AFB signal in the Velocity Loop.
7.8 Field Loop Block Figure 15 Field Enable (331, ICR) Field Enable must be set to True in order for the Elite Pro to produce any field output.

or closed loop current control. The field current is regulated by the Field PI loop. Open Loop Field Setpoint (330) When Open Loop Field Select is True, this parameter controls the Field Conduction Angle. Note that this signal can be scaled down if the drive enters the Field Economy mode. Field Conduction Angle (328, Read-Only) This parameter shows the level of field conduction.
Field Crossover Enable (423, ICR) Field Crossover control is enabled when set to True. Field Crossover Setpoint (425) The Armature Feedback level at which Field Crossover operation begins. Typically, this parameter is set to 85%. As the Armature Feedback increases beyond this threshold, the field current is reduced.
Example - Digital Input Using Digital Input 4 to select between two Jog speed references of 20.00% and 40.00%: 1. While the drive is stopped, go to Setup|Programming|Inputs|Digital|Digital Input 4 menu. 2. Set Digital Input 4 Destination to Jog Reference (221). 3.
less than the 100% Calibration value. 100% Calibration (43-47) This calibration value corresponds to the 12 bit value from the A2D when the input signal is at its maximum level. This defines 100% input signal. For proper operation, the 100% Calibration value must be greater than the 0% Calibration value.
Figure 20 Example - Unipolar Analog Input Setup Analog Input 3 as a unipolar current input to control the internal Setpoint C parameter. Define the 4-20mA current input to produce 0.00%-75.00% speed. 1. While the drive is stopped, go to Setup|Programming|Inputs|Analog|Analog Input 3 menu section.

Diameter Ratio should increase to 100.00%. Figure 24 7.13 Relay Outputs Block The Elite Pro has 3 customer configurable form C relay outputs. Each relay can be configured to turn on (or energize) at a programmable level and turn off (or de-energize) at a different level.
5. Set Relay Output 2 Off Value to 48.00 %. Relay Output 2 will energize when the drive speed equals or exceeds 50.00% and will de- energize when the speed equals or falls below 48.00%. A hysteresis level was used to prevent the relay from 'chattering' (continually energizing and de-energizing) when the drive runs at 50.00% speed.

Set the Frequency Gain to 90.00%: Desired Full Scale Output Hertz 1800 Gain × × 2000 2000 The Frequency Output will give a 1800 Hz full-scale signal of Current Feedback.
7.16 Calibration Block Figure 32 Nameplate Drive Current (122, Read-Only) This parameter contains the full load current rating of the drive. Nameplate Motor Current (123) The motor nameplate armature current rating should be entered here. This allows the Elite Pro to scale the Current Feedback signal for proper operation. The Elite Pro can supply up to 150% of this value, but only for a short duration.
Tachometer Type (127) Selects between a DC or an AC tachometer. Since an AC tachometer cannot convey direction of rotation, the armature feedback signal is used to supply the polarity for directional control. Invert Feedback (126) The encoder and tachometer feedback signals are polarity sensitive. The polarity is used to determine the direction of rotation of the motor.
System Status (238) An internal status register that can be decoded to show the source of a processor reset: power-on, illegal address, software, watchdog or external reset. Reset Source Hex Code Power-On 0x8000 Illegal Address 0x1000 Software 0x0400 Watchdog 0x0200 External None of above Table 13: System Status...
One stop bit should be used with Even or Odd parity, and two stop bits should be used with No parity. However, at very high baud rates, like 38400, Carotron recommends that the Stop Bits setting in the master be set to two stop bits regardless of the setting in the Elite Pro or other slave devices.
7.20 Miscellaneous Block - MOP The MOP (Motor Operated Potentiometer) block provides a means to control a reference level via external contact closures for Increase, Decrease, and Reset. Increase (316) Figure 37 When True, the Output increases at a rate controlled by Increase Time up to a maximum value determined by Max Value.
11. Go to Setup|Programming|Miscellaneous Parameters|MOP menu section. 12. Set Increase Time and Decrease Time to 20.0 seconds. 13. Set Max Value to 50.00%, Min Value to 0.00%, and Reset Value to 5.00%. 14. Go to Setup|Programming|Miscellaneous Parameters|Internal Links menu section 15.
7.22 Miscellaneous Block - Thresholds The threshold block can be used to monitor the level of an internal parameter. A threshold can then be set to select between two setpoints. The threshold block contains two identical threshold detectors designated A and B. Input (177, 183) The value of the internal parameter that serves as the control for the switch.
Figure 41 7.23 Miscellaneous Block - Timer The timer block is a modified version of the threshold block. Instead of monitoring a parameter as the threshold block does, a timer is monitored. When the timer exceeds the threshold, a switch position is toggled, sending selected levels to the output.

Armature Current Foldback Status (252, Read-Only) This status parameter indicates when the drive is in Foldback mode and is limiting the current output to a maximum of 107%.
to reset drive faults externally. Internal Fault Reset (485) The Internal Fault Reset displays the status of the Fault Reset pushbutton on the control board. Power On Reset (327, Read-Only) The Power On Reset is used to automatically clear any latched faults on power up. Note: This parameter is not directly accessible for viewing from the keypad.
Polarity (358) The Polarity parameter controls whether the PI Output needs to be unipolar (positive only) or bipolar (positive and negative). Deadband (354) The Deadband adjustment is used to provide a window of tolerance in the error signal that the integral circuit will ignore. This is commonly used to ignore small dancer movements. Reset (357) When True, resets the PI Output to zero.

Inertia Compensation (449) Additional torque is required by the winder drive when the line is accelerating. This parameter is used in conjunction with Line Speed to control the amount of additional Inertia Torque. Inertia Torque (454, Read-Only) The amount of additional torque supplied to the winder drive when the line is accelerating. Friction Compensation (448) Torque is required to overcome the dynamic friction in the mechanics of the drive train.
Diameter Memory Reset (447) The diameter calculator provides a diameter memory function to maintain the speed based diameter levels during stop. This allows the CTCW block to provide the required torque to maintain constant/taper tension even when the line is stopped. When this parameter is True, the diameter memory is reset.
