Requirements with regard to the brake cable (connection BD1/BD2):

ƒ 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 In the case of a permanent magnet holding brake, observe the correct

polarity of the brake cable.

– If the terminals are inverted, the brake does not release. As the motor is

running against the closed brake, the brake can be destroyed.

ƒ Apply the shield to PE on both sides.

Requirements with regard to the supply voltage U

(connection +/-):

ƒ Always supply the motor brake control with a separate 24 V supply.

– A common supply of the motor brake control and the controller control

card is not permissible, as otherwise the basic insulation between the two

components is reduced.

ƒ Set U

so that the o perating voltage of the brake is within the permissible

range and the maximum supply voltage of the motor brake control is not

exceeded.
