Motor Modules with Cold Plate

8.1

Description

A motor module is a power unit (inverter) that provides the power supply for the connected
motor(s). Energy is supplied from the Infeed Module. 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

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).
Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the supply
has been disconnected.
The protective cover may only be opened after this time has expired.
When opening the protective cover for the DC link, you must press the release catch. 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 further. If this is not carefully observed, it can
result in subsequent damage and accidents.
