Output Signal - Fastech Ezi-STEP-BT-42 Series Operating Manual

10.2 Output signals
As the output signals from the driver, there are the photocoupler outputs (Alarm, In-Position)
and the line driver outputs(encoder signal). In the case of photocoupler outputs, the signals
indicate the status of internal photocouplers.
Alarm(Pin: 5) Run/Stop(pin : 9)
◆ ◆ Alarm Output
The Alarm output indicates [ON] when the driver is in a normal operation. If a protection
mode has been activated, it goes [OFF]. A host controller needs to detect this signal and
stop sending a motor driving command. When the driver detects an abnormal operation
such as overload or overcurrent of a motor, it sets the Alarm output to [OFF], blinks the
Alarm LED, disconnects the power to a motor, and stops the motor, simultaneously.
It operates reversely compare to Normal mode, when you set Inverse mode.
◆ ◆ Run/Stop Output
Run/Stop Output state is[ON] when motor positioning is completed.
It operates reversely compare to Normal mode, when you set Inverse mode.
