Recommended Motor Module
For every motor, Chapter "Motor overview/Motor Module assignment/power cables
(Page 74)" recommends a Motor Module corresponding to its stall (starting) current.
The maximum torque that can be temporarily achieved using this Motor Module is listed in
the tables of this manual as
M
max inv
.
•
When configuring intermittent or overload operation, check whether a larger Motor
Module is required to provide the necessary peak current.
