Wiring Example with Stop Category 2

The machine receives an operational stop (disable) command and brakes the drive using the set braking ramp (STOPMODE and ACTFAULT parameters set to 1).

The drive is braked in a controlled manner during the stopping (disabling) procedure. If the speed VEL0 is undershot, the holding brake is applied and the output stage is disabled. In this case, there is no interruption of the electrical supply.

If the electrical supply is switched off, not only will the controlled braking procedure be performed, but the mains supply and the holding brake will also be electrically isolated following a time period set at the time relay.
