Operation With Standard Motors
General Information
The tables below show the nominal powers P
be operated at the respective drive controller. The data are subject to the fol‐
lowing conditions:
● motor design:
4-pole standard motor (2 pole pairs) with rated voltage 3 AC 400 V, 50 Hz
at mains voltage U
4-pole standard motor (2 pole pairs) with rated voltage 3 AC 460 V, 60 Hz
at mains voltage U
● assigned mains choke is used
● operation at minimum switching frequency f
● rotary field at output with f
● ambient temperature T
● overload ratio K = P
"UEL_P_e"
● type of mains connection: individual supply
When choosing standard motors for HMS/HMD, select an appro‐
priate HMV supply unit. Observe the performance data P
P in the performance profile "UEL_P_e" of the supply unit.
