Requirements on 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 on 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.
