Input Signal
- Input signals of the drive are all photocoupler protected. The signal shows the status of internal photocouplers [ON: conduction], [OFF: Non-conduction], not displaying the voltage levels of the signal.
- 1. CW, CCW Input
- This signal can be used to receive a positioning pulse command from a user host motion controller. The user can select 1-pulse input mode or 2-pulse input mode (refer to switch No.1, SW1). The input schematic of CW, CCW is designed for 5V TTL level. When using 5V level as an input signal, the resistor Rx is not used and connect to the drive directly. When the level of input signal is more than 5V, Rx resistor is required. If the resistor is absent, the drive will be damaged! If the input signal level is 12V, Rx value is 680ohm and 24V, Rx value is 1.8Kohm.
- 2. Servo On/Off Input
- This input can be used only to adjust the position by manually moving the motor shaft from the load-side. By setting the signal [ON], the drive cuts off the power supply to the motor. Then, one can manually adjust output position. When setting the signal back to [OFF], the drive resumes the power to the motor and recovers the holding torque. When driving a motor, one needs to set the signal [OFF].
- 3. Alarm Reset Input
- When a protection mode has been activated, a signal to this alarm reset input cancels the Alarm output.
 - ※ By setting the alarm reset input signal [ON], cancel the Alarm output. Before cancel the Alarm output, have to remove the source of alarm.

Output Signal
- Output signals from the drive are photocoupler protected: Alarm, In-Position and the Line Drive Outputs (encoder signal). In the case of photocoupler outputs, the signal indicates the status of internal photocouplers [ON: conduction], [OFF: Non-conduction], not displaying the voltage levels of the signal.
- 1. Alarm Output
- The Alarm output indicates [ON] when the drive 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 drive detects an abnormal operation such as overload or over current of the motor, it sets the Alarm output to [OFF], flashes the Alarm LED, disconnect the power to a motor and stops the motor simultaneously.
- [Caution] Only at the Alarm output port, the photocoupler isolation is in reverse. When the drive is in normal operation the Alarm output is [ON]. On the contrary when the drive is in abnormal operation that start protection mode, the Alarm output is [OFF].
- 2. In-Position Output
 - In-Position signal is [ON] when positioning is completed. This signal is [ON] when the motor position error is within the value set by the switch SW4.
- 3. Encoder Signal Output
- The encoder signal is a line drive output. This can be used to confirm the stop position.
