1) The circuit for protecting the brake against overvoltage is integrated 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 X12 and X22 on double motor modules.
The BR- cable must not be connected directly to electronic ground (M).
Only protective extra-low voltages (DVC A) 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.
