Parameter Group 4 –
Motor Control modes, Speed Loop Gains, Current limits.
Incorrect adjustment of parameters in menu group 4 can cause unexpected behaviour of the motor and any connected
machinery. It is recommended that these parameters are only adjusted by experienced users.

Selects the motor control method. An auto-tune must be performed if setting 0 or 1 or 3 is used.

1.
When set to 1, (All Motors) the drive immediately carries out a non-rotating auto-tune to measure the motor parameters for
optimum control and efficiency. Following completion of the auto-tune, the parameter automatically returns to 0.
2.
When set to 2, (PM Motors only), the drive carries out a stationary Encoder offset measurement (see section 12.7) and
populates P6-09 with the result. Following completion, the parameter automatically returns to 0.
P4-03
Vector Speed Controller Proportional Gain
0.1
400
50.0
%
Sets the proportional gain value for the speed controller. Higher values provide better output frequency regulation and response.
Too high a value can cause instability, Vibration or even over current trips. For applications requiring best possible performance, the
value should be adjusted to suit the connected load. (Not active when P4-01=2, Enhanced V/F mode)
P4-04
Vector Speed Controller Integral Time Constant
0.001
1.000
0.050
s
Sets the integral time for the speed controller. Smaller values provide a faster response in reaction to motor load changes, at the risk
of introducing instability. For best dynamic performance, the value should be adjusted to suit the connected load.
(Not active when P4-01=2, Enhanced V/F mode)

Maximum Motoring Torque Limit
0.0
500.0
200.0
%
When operating in Vector Speed motor control modes (P4-01 = 0, 1, 3), this parameter defines the maximum torque limit.

Generator Mode Max. Torque Limit (Maximum Regenerative Torque)
0.0
500.0
150.0
%
Active only in Vector Speed motor control modes (P4-01 = 0 or 1). Sets the maximum regenerating torque allowed by the Optidrive
P2 Elevator drive.

V/F Characteristic Adjustment Frequency
0.0
100.00
0.0
%
When operating in V/F mode (P4-01 = 2), this parameter in conjunction with P4-11 sets a frequency point (as a % of P1-09) at which
the voltage set in P4-11 (as a % of P1-07) is applied to the motor. Care must be taken to avoid overheating and damaging the motor
when using this feature.

0: Disabled.
1: Enabled. All Optidrive P2 drives feature electronic thermal overload protection for the connected motor, designed to protect the
motor against damage. An internal overload accumulator monitors the motor output current over time, and will trip the drive if the
usage exceeds the thermal limit. When P4-12 is disabled, removing the power supply from the drive and re-applying will reset the
value of the accumulator. When P4-12 is enabled, the value is retained during power off.

Sets the proportional gain value for the speed controller during low speed operation, low speed operation is defined as a speed value
less than the value set in P4-17 (Low speed Gains transition point)
This parameter is only active if P4-17 (Low speed Gains transition point) is >0. (Not active when P4-01=2, Enhanced V/F mode)

Sets the Integral gain value for the speed controller during low speed operation, low speed operation is defined as a speed value less
than the value set in P4-17 (Low speed Gains transition point)
This parameter is only active if P4-17 (Low speed Gains transition point) is >0. (Not active when P4-01=2, Enhanced V/F mode)
