Parameterizing the "Motor holding brake like sequence control, connection via BICO" option
To parameterize the "Motor holding brake like sequence control, connection via BICO"
option, proceed as follows:
1. Set the opening time of the brake (p1216).
After activating the holding brake (opening), the speed/velocity setpoint zero is active
during this time. The speed/velocity setpoint is then enabled after this time.
The time should be set greater than the actual opening time of the brake. The drive does
not then accelerate when the brake is closed.
2. Set the closing time of the brake (p1217).
The drive still remains in closed-loop control at standstill with speed/velocity setpoint zero
after OFF1 or OFF3 and activation of the holding brake (closing). The pulses are
suppressed when this time expires.
The time should be set greater than the actual closing time of the brake. In this way, the
pulses are only suppressed when the brake is closed.
3. To open the "Opening the brake (Page 294)" dialog, click "Open brake".
Make the required settings in the dialog.
4. Interconnect the "Open brake command" (p0899.12) signal source to the required
parameters. Several connections are possible.
5. To open the "Closing the brake (Page 294)" dialog, click "Close brake".
Make the required settings in the dialog.
6. Interconnect the "Close brake command" (p0899.13) signal source to the required
parameters. Several connections are possible.
The "Open brake" and "Close brake" settings are processed logically via the flip-flop. The
"Open brake" and "Close brake" signals are then present at the outputs of the flip-flop.
