4.2 Operating modes
S with synchronous motors (FD)
– 1FT6, 1FK6 and 1FK7 servo motors
– 1FW6 built–in torque motors (direct drives)
– 1FN linear motors
S with induction motors (MSD–IM)
– 1PH main spindle motors
– 1PM hollowshaft motors for main spindle drives (direct drives)
– standard induction motors (sensorless)
If IM operation is selected, only inverter pulse frequencies of
4 kHz and 8 kHz are permissible.
S with synchronous motors (MSD–SRM)
– 1FE1 main spindle motors
– 2SP1 motor spindle
Note
For the MSD–SRM operating mode (high–speed MSD synchronous
applications), inverter pulse frequencies are set that differ from the rated
frequencies. This consequently ensures an optimum ratio between the inverter
pulse frequency and the output frequency.
The derating resulting from this should be taken into account when selecting
the power module.
The frequencies relevant when engineering the system should be appropriately
taken from the following documentation.
