Siemens SINAMICS G120C Function Manual

3.6 Recommendations for stable operation
The following preconditions must be satisfied to ensure disturbance-free inverter operation
with the extended functions enabled:
● Motor and inverter are adequately dimensioned for this application:
– The inverter is operated below its current limit.
– The rated currents of the motor and inverter must not differ by more than a factor of 5:
Inverter rated current/motor rated current < 5 (r0207[0] / p0305 < 5).
● Before commissioning the safety functions, optimally set the closed-loop control:
– Carry out motor data identification at standstill.
– Carry out a rotating measurement.
– Avoid multiple speed overshoots when settling after a setpoint change.
– Avoid reversing the motor within less than 2 s.
