If the drives enable terminal is opened, the drives output is disabled and the motor will coast to a stop. The drive will not re-enable for 0.5s after the
enable terminal is closed again.
10.1 Drive reset
If the enable terminal is opened, the drive’s output is disabled and the motor will coast to a stop. The drive will not re-enable for 1.0s after the enable
terminal is closed again.
*
Following a drive trip, opening and closing the enable terminal will reset the drive. If the run forward or run reverse terminal is closed, the drive will
run straight away.
**
Following a drive trip and a reset via the stop/reset key, the enable, run forward or run reverse terminals will need to be opened and closed to allow
the drive to run. This ensures that the drive does not run when the stop/reset key is pressed.
The enable, run forward and run reverse terminals are level triggered apart from after a trip where they become edge triggered. See
*
and
**
above.
If the enable and run forward or enable and run reverse terminals are closed when the drive is powered up, the drive will run straight away up to a set
speed.
If both the run forward and run reverse terminals are closed, the drive will stop under the control of the ramp and stopping modes set in Pr
