– The rated currents of the motor and inverter must not differ by more than a factor of 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.
