Function
Servo alarm: Turns OFF when an error is detected.
Detection during servo motor rotation: detects when the servo motor is rotating at a speed higher than the motor speed
setting.
Servo ready: ON if there is no servo alarm when the control/main circuit power supply is turned ON.
Phase-A signal
Two-phase pulse encoder output pulse signal
Phase-B signal
Phase-C signal
Zero-point pulse signal
Alarm code output: Outputs 3-bit alarm codes.
Connected to frame ground if the shield wire of the I/O signal cable is connected to the connector shell.
Turns ON when whether the motor speed is within the setting range is detected and if it matches the reference speed
value.
Turns ON when the number of position error pulse reaches the value set.
Reserved terminals
