6.8.5 Implementation of the Stop Category 2
The machine receives an operational stop (disable) command and brakes the drive using the set
braking ramp (STOPMODE & ACTFAULT parameters set to 1).
The drive is braked in a controlled manner during the stopping (disabling) procedure. If the speed
VEL0 (see sequence diagram in chapter 6.4) 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.
