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. comments: In some critical error situations, the output stage is disabled immediately. Then the setting ACTFAULT = 1 has no function (see description ERRCODE *). With the parameter ERRCNFG can be enforced on individual fault the immediate blocking of the amplifier. The setting ACTFAULT = 1 then has no function. |
