Recommended means of commissioning:
For correct operation under SLVC / VC control it is imperative that the name plate data of the motor (P0304 -
P0310) is correctly entered and that the motor data identification (P1900) must be carried out on a cold motor.
It is also necessary to ensure that the motor ambient temperature is correctly entered in P0625 if this is significantly
different from the default value of 20°C.
This must be done after the quick commissioning has been completed (P3900) but before the motor data identifica-
tion measurements are carried out.
Optimisation:
The following parameters can be adjusted by the user to improve performance.
• P0003 = 3
• P0342: Total / motor inertia ratio
Sensorless Vector Control (SLVC):
• P1470: P gain (SLVC)
• P1472: I term (SLVC)
• P1610: Continuous torque boost (SLVC, open loop boost)
• P1750: Control word of motor model
Vector Control (VC):
• P1460: P gain
• P1462: I term
