The circuit for protecting the brakes against overvoltage is in the Motor Module and does not need to be installed externally. The max. load
current is 2 A, the min. load current 0.1 A.
Note
The total length of the shielded power cables (motor supply cables and DC link cables) must
not exceed 350 m.
Note
The motor brake must be connected via connector X11. The BR - cable must not be
connected directly to electronic ground (M).
Warning
Only protective extra-low voltages (PELVs) that comply with EN60204-1 must be connected
to all connections and terminals between 0 and 48 V DC.
The voltage tolerances of the motor holding brakes must be taken into account.
