4. Operation Using I/O Signals

4.3 Push Mode

Use the PIO pattern of this mode if you wish to perform position control and push-motion operation using pulse train

input from a PLC.

Set User Parameter No. 25 (PIO pattern selection) to “1.”

4.3.1 Explanation of I/O Signals

Pin No. Signal Name Remarks

1 24 V External 24 V

2 0 V External ground

If the controller is used in the open collector mode, also use this

pin for the COMMON signal for command pulses as well as the

0V signal for the controller’s control power.

3 IN0 SON Servo-on signal

4 IN1 TL Torque-limit selection signal

5 IN2 HOME Homing signal

6 IN3 RES/DCLR Reset signal/deviation-counter clear signal

7 OUT0 SV Servo-on output

8 OUT1 INP/TLR Positioning complete signal/torque limit signal

9 OUT2 HEND Homing complete signal

10 OUT3 *ALM Alarm signal

11 /PP Command pulse

12 PP Command pulse

Not connected if the controller is used in the open collector

mode.

13 /NP Command pulse

14 NP Command pulse

Not connected if the controller is used in the open collector

mode.

 Servo-on Command Input (SON)

The servo remains on while this signal is ON.

The actuator can be operated while the SON signal is ON.

While this signal is OFF, the actuator does not operate even when the controller power is supplied.

If the SON signal is turned OFF while the actuator is operating, the actuator will decelerate at the forced-stop torque

until it stops. After the actuator stops, the servo will turn off and the motor will enter a free-run state.

At this time, the function specified by the applicable parameter (electromagnetic brake) becomes active.

 Reset Signal Input (RES)

This signal resets the alarms currently detected by the controller.

You can turn the RES signal ON to reset the alarms currently detected by the controller.

Caution: This signal cannot reset cold-start level alarms. Identify the cause of each alarm and remove the

cause before restarting the controller.

 Deviation-counter Clear Signal (DCLR)

While the TL signal is ON, the RES signal functions as the deviation-counter clear signal (DCLR).

The deviation counter is cleared continuously while this signal is ON.

Upon completion of push-motion operation, you can clear the deviation counter by inputting this signal.
