P-35 Analog Input 1 Scaling / Slave Speed Scaling
Analog Input 1 Scaling. The analog input signal level is multiplied by this factor, e.g. if P-16 is set for a 0 – 10V signal , and the scaling
factor is set to 200.0%, a 5 volt input will result in the drive running at maximum frequency / speed (P-01)
Slave Speed Scaling. When operating in Slave Mode (P-12 = 9), the operating speed of the drive will be the Master speed multiplied
by this factor, limited by the minimum and maximum speeds.
P-36 Serial Communications Configuration
Index 1 : Address
Index 2 : Baud Rate
Index 3 : Communication loss protection
This parameter has three sub settings used to configure the Modbus RTU Serial Communications. The Sub Parameters are
Index 1 : Drive Address : Range : 0 – 63, default : 1
Index 2: Baud Rate & Network type: Selects the baud rate and network type for the internal RS485 communication port.
For Modbus RTU: Baud rates 9.6, 19.2, 38.4, 57.6, 115.2 kbps are available.
For CAN Open: Baud rates 125, 250, 500 & 1000 kbps are available.
Index 3: Watchdog Timeout: Defines the time for which the drive will operate without receiving a valid command telegram to
Register 1 (Drive Control Word) after the drive has been enabled. Setting 0 disables the Watchdog timer. Setting a value of 30, 100,
1000, 3000, 10000, 30000 or 60000 defines the time limit in milliseconds for operation. A '' suffix selects trip on loss of
communication. An '' suffix means that the drive will coast stop (output immediately disabled) but will not trip.
P-37 Access Code Definition
Defines the access code which must be entered in P-14 to access parameters above P-14
P-38 Parameter Access Lock
Setting Function
0 Unlocked
1 Locked
P-39 Analog Input 1 Offset
Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal. This parameter
operates in conjunction with P-35, and the resultant value can be displayed in P00-01.
The resultant value is defined as a percentage, according to the following :-
P00-01 = (Applied Signal Level(%) - P-39) x P-35)
P-40 Index 1 : Display Scaling Factor
Index 2 : Display Scaling Source
Allows the user to program the Optidrive to display an alternative output unit scaled from either output frequency (Hz), Motor
Speed (RPM) or the signal level of PI feedback when operating in PI Mode.
Index 1: Used to set the scaling multiplier. The chosen source value is multiplied by this factor.
Index 2 : Defines the scaling source as follows :-
Setting Function
0 Motor Speed
1 Motor Current
2 Analog Input 2 Signal Level
3 PI Feedback
P-41 PI Controller Proportional Gain
PI Controller Proportional Gain. Higher values provide a greater change in the drive output frequency in response to small changes
in the feedback signal. Too high a value can cause instability
P-42 PI Controller Integral Time
PI Controller Integral Time. Larger values provide a more damped response for systems where the overall process responds slowly
Optidrive E3 Advanced Technical Manual Issue 05.Docx
Description
When enabled, on start up the drive will attempt to determine if the motor is already
rotating, and will begin to control the motor from its current speed. A short delay may be
observed when starting motors which are not turning.
Spin start is only activated following the events listed, otherwise it is disabled.
Description
Enables the internal brake chopper with software protection for a 200W
continuous rated resistor
Enables the internal brake chopper without software protection. An external
thermal protection device should be fitted
As setting 1, however the Brake Chopper is only enabled during a change of the
frequency setpoint, and is disabled during constant speed operation
As setting 2, however the Brake Chopper is only enabled during a change of the
frequency setpoint, and is disabled during constant speed operation.
Description
All parameters can be accessed and changed
Parameter values can be displayed, but cannot be changed except P-38.
Description
Scaling is applied to the output frequency if P-10 = 0, or motor RPM if P-10 > 0.
Scaling is applied to the motor current value (Amps)
Scaling is applied to analog input 2 signal level, internally represented as 0 – 100.0%
Scaling is applied to the PI feedback selected by P-46, internally represented as 0 – 100.0%
