Safety instructions

During installation the notes given in the documentation for 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.

Note!

The supply status can be reported to the standard device via the error channel.

For more information, please see the software manual or the online help (see

description of C02609/8).
