Stop!
Requirements concerning the brake cable (connection BD1/BD2):
ƒ The brake cables must be shielded if they are incorporated in the motor
cable.
– Operation with unshielded brake cables can destroy the motor brake
control.
– We recommend the use of Lenze system cables (motor cable with
separately shielded additional cores).
ƒ When using a permanent magnet holding brake, ensure the correct polarity
of the brake cable.
– If the terminals are reversed, the brake does not release. Since the motor
runs against the closed brake, the brake can be destroyed.
ƒ Connect the shield on both sides of PE.
Requirements concerning the supply voltage U
DC
(connection +/-):
ƒ The motor brake control must always be supplied with a separate 24 V
supply.
– A common supply of the motor brake control and the control card of the
controller is not permissible since otherwise the double insulation
between both components would be reduced.
ƒ Set U
DC
so that the operating voltage of the brake is within the admissible
range and the maximum supply voltage of the motor brake control will not
be exceeded.
