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!
