Control signal 
power supply

COM+

COM–

1

17

• Connected to the  +  terminal of an external DC power supply (12 to 24 V)
• Use a 12 V (

±

5%) to 24 V (

±

5%) power supply.

• Connected to the  –  terminal of an external DC power supply (12 to 24 V).
• The power supply capacity differs depending on the configuration of the 

input/output circuits used. A capacity of more than 0.5A is recommended.

Emergency 
stop input

EMG-
STP

2

• When connection with COM– is opened, emergency stop input error (error 

code No.39) occurs, and the circuit trips.

• Tripping can be reset using an alarm clear input initiated by specifying point 

0 or assigning the multi-function inputs (EX-IN1, EX-IN2).

Point specifying 
input

• Specify an operation point number when operation command is input.
• The number at which operation point can be specified depends on the 

number of points set by SV.Pr57.

• SV.Pr58 can be used for setting input logic.
  When the point described below is specified, special operation is 

performed.

1)Specify point 0, and input a strobe signal, then alarm is cleared.
2)Specify the maximum point number specified in SV.Pr57, and input a 

strobe signal, then system returns to the home position.

3)Specify the maximum point number specified in SV.Pr57 –1 and input a 

strobe signal, then high-speed normal rotation jog is performed.

4)Specify the maximum point number specified in SV.Pr57 –2 and input a 

strobe signal, then high-speed reverse rotation jog is performed.

CCW over-
travel
inhibit input

CCWL

19

• CCW drive prohibition input (CCWL).
• Connect so as to open COM– connection when movable part of the 

equipment exceeds the movable range in CCW direction.

• When this input is open, operation command in CCW direction is not 

issued. (Torque is generated)

• SV.Pr53, 54, and 55 enable for setting of valid/invalid, input logic, and 

operation.

CW over-travel
inhibit input

CWL

20

• CW drive prohibition input (CWL).
• Connect so as to open COM– connection when movable part of the 

equipment exceeds the movable range in CW direction.

• When this input is open, operation command in CW direction is not issued. 

(Torque is generated)

• SV.Pr53, 54, and 55 enable setting of valid/invalid, input logic, and 

operation.

Home sensor 
input

Z-LS

21

• Connect so as to close the home sensor input when system is in the 

vicinity of home position (default).

  SV.Pr56 can be used for setting input logic.
• Connected to the home sensor signal.

Servo-ON sig-
nal input

SRV-ON

23

• Connect so as to close the home sensor input when system is in the 

vicinity of home position.

  Pr56 can be used for setting input logic.
• When servo driver is connected to COM– of control signal power supply, it is 

set in servo-ON condition.

• When connection to COM– is opened, servo-OFF condition is set, and 

energization of motor is cut off.

• Dynamic brake operation and deviation counter clearing operation in servo-OFF 

condition can be chosen by SV.Pr69 (sequence at servo-off).

• SV.Pr5D enable setting of valid/invalid.
<Notes>
1)When shifting from servo-OFF to servo-ON, make sure that the motor is 

stopped.

2)After shifting to servo-ON, allow 100ms or more before giving an 

instruction.

3)Frequent repeating of servo-ON/OFF may damage the dynamic brake 

circuit contained in servo driver. Avoid such a use.
