9.3.6. Group 4 Parameter Listing
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.

P4-02 Motor Parameter Auto-tune Enable
0
1
0
-
When set to 1, the drive immediately carries out a non-rotating autotune to measure the motor parameters for optimum control and
efficiency. Following completion of the autotune, the parameter automatically returns to 0.
P4-03 Vector Speed Controller Proportional Gain
0.1
400.0
50
%
Sets the proportional gain value for the speed controller when operating in Vector Speed motor control modes (P4-01 = 0 or 1).
Higher values provide better output frequency regulation and response. Too high a value can cause instability or even over current
trips. For applications requiring best possible performance, the value should be adjusted to suit the connected load by gradually
increasing the value and monitoring the actual output speed of the load until the required dynamic behaviour is achieved with little or
no overshoot where the output speed exceeds the setpoint.
In general, higher friction loads can tolerate higher values of proportional gain, and high inertia, low friction loads may require the gain
to be reduced.
P4-04 Vector Speed Controller Integral Time Constant
0.000
2.000
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.
P4-05 Motor Power Factor Cos Ø

-
When operating in Vector Speed motor control modes, this parameter must be set to the motor nameplate power factor.
P4-07 Maximum Motoring Current Limit

200

%
This parameter defines the maximum output current the drive will provide to the motor before reducing the output frequency to attempt
to limit the current.

Enabled
All Optidrives 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.

It.trp :
When the overload accumulator reaches the limit, the drive will trip on It.trp to prevent damage to the motor.
1
Current Limit Reduction :
When the overload accumulator reaches 90% of the limit, the current limit will be internally
set to 100% of P1-08 in order to prevent an It.trp. The current limit will return to the setting in P4-07 when the overload
accumulator reaches 10%.
