3.8 I/O Signal Controls and Function
153
(10) Pause (STP) PLC Output Signal
When this signal is turned “ON”, the actuator movement is decelerated and stopped. When it is
turned “OFF”, the actuator movement is restarted.
The acceleration in the operation restart or the deceleration in stopping operation, is expressed
as the value for the acceleration/deceleration for the position No. set using the specified
position No. resister in the Position 1/Simplified Direct Value Mode, and as the value set in the
acceleration/deceleration register in the Direct Numeric Specification Mode.
(11) Zone 1 (ZONE1) PLC Input Signal
Zone 2 (ZONE2) PLC Input Signal
These signals are turned ON when the current position of the actuator is within the set domain
and turned OFF when the current position is out of the set domain.
The zone is set using the user parameters.
The Zone 1 Signal is set using the parameter No.21 “Zone Positive Boundary 1 “+” Side” and
No.22 “Zone Negative Boundary 1 “–” Side”.
The Zone 2 Signal is set using the parameter No.23 “Zone Positive Boundary 2 “+” Side” and
No.24 “Zone Negative Boundary 2 “–” Side”.
The Zone 1 Signal and Zone 2 Signal become effective when the homing operation is
completed.After that, even during the servo OFF, it is effective.

(12) + Jog (JOG+) PLC Output Signal
- Jog (JOG-) PLC Output Signal
This signal is the command for the jog operation startup or inching operation startup.
If a + command is issued, the actuator will operate in the direction opposite home. When a
- command is issued, the actuator will operate in the direction of home.
1) Jog operation
Jog operation can be performed when the jog/inch switching (JISL) signal is OFF.
While the “JOG+” is turned “ON”, the movement direction is to the opposite of the home and
when it is turned “OFF”, the actuator is decelerated and stopped.
While the “JOG-” is “ON”, the actuator will operate in the direction of home and when it is turned
“OFF”, it is decelerated to a stop.
The operation is performed based on the set values.
x The speed for an operation is provided with the value set in Parameter No.2 “PIO JOG
Speed”.
x The acceleration/deceleration conforms to the rate acceleration/deceleration (the specific
value varies depending on the actuator).
x When both the JOG+ and JOG- signals are turned “ON”, the actuator is decelerated and
stopped.
