Fast stop
This function is used to ramp down to zero speed according to a predefined
deceleration time (parameter
FST STP DCCL TIME). The drive decelerates to
zero speed on receiving the
FAST STOP PTR command. The FAST STOP
PTR should be active (according to the selection of pointer value) for enabling the
Fast stop command. After the command, the input must be inactive for the next start
sequence to happen.
When receiving a Fast stop command, the drive gives a FAST STOP warning
message on the panel.
If the drives are in a Master/Follower configuration and in EXT2 control, all the drives
will stop on a Fast stop command from any of the drives.
