MFI (frequency inverter)
A shielded cable should be used for the motor control
unit MFI for EMC reasons. The shield of this cable should
be laid at the motor feeder connector and at the motor.
The required number of cores can vary between 5 cores
+ PE (for motors with thermistor, without brake) and 9
cores + PE (for motors with thermistor, brake and high-
speed contact), depending on the motor that is used. The
cable length may not exceed 5 m.

Unassigned
In this variant, the brake can be applied
independently of the motor. Hazardous
voltage can thus also be present at the
terminals of the brake even when the
motor is stationary.
The brake must be connected via the
separate supply cables for the brake.
Depending on the speed, the brake does
not receive the nominal voltage via the
motor supply cables. Damage to the
motor or brake cannot be excluded.
Further information should be taken from the description
for your motor.
