Notes on the selection tables
The selection tables represent the combinations of servo motors and servo inverters. The
serve as a rough overview.
In the case of the servo inverters, the overload capacity depending on the switching frequency
in the default setting is taken into consideration. For more information, please refer to the
inverter documentation.

Notes
With a zero speed rpm, the standstill torque and
standstill current are to be reduced by 30 % after
2 % seconds.
For applications that require a longer holding of the
standstill torque, it is recommended to hold the
drive via the holding brake and, for instance,
reducing the current by inverter disable.
With an active load observe (e. g. vertical drive axes,
hoists, test benches, unwinders).
Can usually be used with a passive load (e. g.
horizontal drive axes).
Due to a derating of the inverter output current to
the derating speed, for some inverters the
achievable max. standstill torque is smaller than the
max. speed when the value of 5 Hz is not reached.
