Stop!
The motor brake control includes an electronic switch which can control a 24 V
motor holding brake.
The motor brake control may only be connected with motor holding brakes
which correspond to the permissible data mentioned in the technical data. (If
required, the holding brake without motor brake control must be controlled
via a digital output and a coupling relay).
If the permissible data mentioned in the technical data are not complied with:
ƒ
the motor brake control can be destroyed.
ƒ
a safe operation of the motor holding brake cannot be guaranteed.
Further notes in the documentation of the standard device must be observed!
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.
