Subindex 5: Brake: Control logic
The control logic of the holding brake can be inverted.
Selection list (Lenze setting printed in bold) Info
0 Positive logic Positive logic means:
• Release of the holding brake: The 1-signal serves to
trigger the brake output via bit 14 in the CiA402
control word or by the device state machine (relay
contact closed).
• In the CiA402 status word, bit 14 is set (holding brake
released).
Negative logic means:
• Level inversion of the relay output.
• Release of the holding brake: The 1-signal does not
trigger the brake output via bit 14 in the CiA402
control word or by the device state machine (relay
contact is open).
• In the CiA402 status word, bit 14 is set (holding brake
released).

Subindex 6: Brake monitoring: Response
In the controlled state, the holding brake is monitored cyclically for the presence of the brake current.
Since, after connecting the holding brake, the brake current builds up in a time-delayed manner as a function of
inductance, an open circuit, a terminal short circuit, or a missing brake supply is detected with a delay.
When monitoring trips, the response set here will be activated.
Note:
The holding brake is not monitored in the non-triggered state!
