Motor Modules with Cold Plate

7.1

Description

7.1
A motor module is a power unit (inverter) that provides the power supply for the connected
motor(s). Power is supplied by means of the DC link of the drive unit. A motor module must
be connected to a control unit via DRIVE-CLiQ. The open-loop and closed-loop control
functions for the motor module are stored in the control unit.
One motor can be connected to single motor modules and two motors can be connected to
double motor modules.

Safety Information

7.2
Danger
Only motors with a safe electrically isolated holding brake may be connected. The brake
conductors must also be safely electrically isolated.
If the motor power cable is connected to intermediate terminals, the power cables and brake
cables must be routed apart (≥ 300 mm).
Warning
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. The protective cover must not be opened until this time
has elapsed.
When opening the protective cover for the DC link, you must activate the release. A suitable
tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used, otherwise this could result in secondary damage
or accidents.
