Operating Instructions – MOVIMOT® MM03C - MM3XC

Selectable special functions MM..C-503-00

Startup of Standard Design

Use of relay out-
put with special
functions 7, 9 and
12

The following figure shows the use of relay contact K1 to control the mechanical brake
with brake rectifier BGM.

Important: Please observe the following before startup with brake control BGM:

•

The brake coil must correspond to the supply voltage (e.g. 400 V).

•

Special function 7, 9 or 12 must be activated, otherwise the brake is perma-
nently released. This must also be observed in the case of an exchange of the
MOVIMOT

inverter.

If neither of the listed functions is activated, relay contact K1 functions as ready sig-
nal contact. This means that the brake will be released without enable if the
BGM is used, if it was connected without permission.
