Requirements on the brake cable (connection BD1/BD2):
The brake cables must be shielded.
ƒ
– An 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).
When using a permanent magnet holding brake, ensure a correct polarity
ƒ
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.
Connect the shields on both sides of PE.
