Short Description

Active Fault Mode

Description

The ACTFAULT command is used to specify the response of the drive if a fault occurs.

ACTFAULT=0: If a fault occurs, the output stage is immediately inhibited, the drive coasts down.

ACTFAULT=1: If a fault occurs, an Emergency Stop procedure is initiated, that consists of the following steps.

  1. Switch over the controller mode to velocity control (OPMODE=0)
  2. Change the braking ramp for the velocity control loop (DEC) to the emergency stop ramp (DECSTOP)
  3. Set the internal velocity setpoint to 0 (before the ramp generator).
  4. Start a timer (with time-out = 5 seconds)

As soon as the internal velocity setpoint (after the ramp generator) has reached 0, the output stage is inhibited, and the original controller mode is re-activated. This will also happen if the time-out occurs before the velocity setpoint has reached 0.
