signal
interface
COM+ 1 - 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. -
Control signal power
supply COM−17
- Connected to the [-] terminal of an external DC power supply
(12 to 24 V).
- The power supply capacity varies depending on the configuration of the I/O
circuits. 0.5A or higher capacity is recommended.
-
Emergency stop
input EMG-
STP 2 - When connection with COM−is opened, emergency stop input error (39)
occurs, and the circuit trips.
- Tripping can be reset by inputting alarm clearing. i-1
Point specifying
input P1IN -
P32IN 3,4, 5,
6, 7, 8,
- 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 servo parameter No.57.
- Servo parameter No. 58 can be used for setting input logic.
When the point described below is specified, special operation isperformed.
- Specify point 0, and input a strobe signal, then alarm is cleared.
- Specify the maximum point number specified in Servo parameter No 57, and
input a strobe signal, then system returns to the home position.
- Specify the maximum point number specified in Servo parameter No 57-1,
and input a strobe signal, then high-speed normal rotation jog is performed.
- Specify the maximum point number specified in Servo parameter No 57-2,
and input a strobe signal, then high-speed reverse rotation jog is performed.

CCW over-travel
inhibit input CCWL 19
- CCW over-travel inhibit 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)
- Servo parameter Servo parameter No. 53, 54, and 55 enable for setting of
valid/invalid, input logic, and operation.
i-1
CW over-travel
inhibit input CWL 20
- CW over-travel inhibit 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)
- Servo parameter Servo parameter No. 53, 54, and 55 enable setting of
valid/invalid, input logic, and operation.
i-1
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).
Servo parameter No. 56 can be used for setting input logic. i-1
Servo-ON input SRV-
ON 23
- When servo amplifier 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 Servo parameter No.69 (sequence at
servo-off).
- Servo parameter no.5D enable setting of valid/invalid.
Note. 1 When shifting from servo-OFF to servo-ON, make sure that the motor
is stopped.
Note 2 After shifting to servo-ON, allow 120ms or more before giving an
instruction.
Note 3 Frequent repeating of servo-ON/OFF may damage the dynamic brake
circuit contained in servo amplifier.Avoid such a use.
i-1
Strobe signal input STB 24
- Leave it open normally. When it is connected to COM−of control signal
power supply, the servo amplifier starts operation to a specified point.
- When 10ms or more has passed after setting specified point input, connect the
strobe signal input (STB ) to COM−. It is possible that the servo amplifier is
unable to read specified point input properly.
- Input STB signal 10ms or longer. Also, reset STB signal to opened condition
after receiving BUSY signal from the servo amplifier in order to ensure that
STB signal is received reliably.
