The remote current speed-reference input circuit incorporates a protection circuit to prevent any
internal damage within the drive in the event of an external controller fault. This protection circuit
senses the input current and if this exceeds 25mA, a FET disconnects the external controller
from the drive. This FET will also disconnect the external controller signal when the drive is
powered off.

Operation of digital output
The total current available from the +24V rail, which includes the digital output, is
NOTE
100mA. Therefore if the digital output is providing 30mA, the +24V rail will only
provide 70mA.

If the enable terminal is opened, the drive's output is disabled and the motor will coast to a stop.
The drive cannot be re-enabled for 2 seconds following the opening of the enable terminal.
† Following a drive trip, open and close the Enable terminal to reset the drive. If the Run Forward
or Run Reverse terminal is closed, the drive will run straight away.
