Issue Number 5
The total current available from the +24V rail, which includes the digital
output, is 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.
* Following a Drive trip and a reset via the Stop/Reset key the 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 start when the Stop/Reset key is pressed.
Provide fuse or other over-current protection in status relay circuit.
