9.2 Output Signal

As the output signal from the drive, there are the photocoupler outputs(Alarm, Run/Stop).
The signal status operate as [ON: conduction], [OFF: Non-conduction] of photocoupler
not as the voltage level of signal.
Alarm Output
◆
The Alarm output indicates [OFF] when the drive is in a normal operation. If a protec-
tion mode has been activated, it goes [ON]. A host controller needs to detect this sig-
nal and stop sending a motor driving command. When the drive detects an ab-
normal operation such as overload of overcurrent of a motor, it sets the Alarm output
to [ON], flash the Alarm LED, disconnects the power to a motor, and stops the motor,
simultaneously.
Run/Stop Output
◆
Run/Stop Output state is [ON] when motor positioning is completed. It operates reversely com-
pare to Normal mode, when you set Inverse mode.
