5.
Check that the motor follows the setpoint.
6.
If necessary, increase the voltage boost p1311 until the motor accelerates without
problem.
In applications with a high break loose torque, you must also increase parameter p1312 in
order to achieve a satisfactory motor response.
You have set the voltage boost.
❒
Parameter Description
p1310
Starting current (voltage boost) permanent (factory setting 50%)
Compensates for voltage drops caused by long motor cables and the ohmic losses in
the motor.
p1311
Starting current (voltage boost) when accelerating (factory setting 0%)
Provides additional torque when the motor accelerates.
p1312
Starting current (voltage boost) when starting (factory setting 0%)
Provides additional torque, however, only when the motor accelerates for the first time
after it has been switched on ("break loose torque").
You will find more information on this function in the parameter list and in function diagram
6301 in the List Manual.
