CN1-19 Turn on RES for more than 50 ms to reset the alarm.
Some alarms cannot be deactivated by RES (Reset). Refer to section 8.1.
Turning RES on in an alarm-free status shuts off the base circuit. The base

This device is not designed to make a stop. Do not turn it on during
operation.
CN1-43 To start operation, turn on LSP and LSN. Turn it off to bring the motor to a
