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.
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 30 and Pr 31.
