(13) +Jog (JOG+) PLC output signal
-Jog (JOG-) PLC output signal
These signals are used as starting commands for jog operation or inching operation.
A + command starts the applicable operation in the direction opposite home, while a – command starts the
applicable operation in the direction of home.
[1] Jog
operation
Jog operation can be performed when the jog/inching switching (JISL) signal is OFF.
While JOG+ is ON, the actuator moves in the direction opposite home. When the signal turns OFF, the
actuator will decelerate to a stop.
While JOG- is ON, the actuator moves in the direction of home. When the signal turns OFF, the actuator will
decelerate to a stop.
The specific operation conforms to the values set in the following parameters:
x The actuator moves at the speed corresponding to the value of the parameter specified by the jog
speed/inching distance switching (JVEL) signal.
When the JVEL signal is OFF, the actuator moves at the value of parameter No. 26, “PIO jog speed.”
When the JVEL signal is ON, the actuator moves at the value of parameter No. 47, “PIO jog speed 2.”
x The actuator moves at the rated acceleration/deceleration (the specific value varies depending on the
actuator).
x When both the JOG+ and JOG- signals turn ON, the actuator will decelerate to a stop.
[2] Inching
operation
Inching operation can be performed when the jog/inching switching (JISL) signal is ON.
The actuator moves by the inching distance with every ON input.
While JOG+ is ON, the actuator moves in the direction opposite home. While JOG- is ON, the actuator
moves in the direction of home.
The specific operation conforms to the values set in the following parameters:
x The actuator moves at the speed corresponding to the value of the parameter specified by the JVEL
signal.
When the JVEL signal is OFF, the actuator moves at the value of parameter No. 26, “PIO jog speed.”
When the JVEL signal is ON, the actuator moves at the value of parameter No. 47, “PIO jog speed 2.”
x The actuator moves by the travel corresponding to the value of the parameter specified by the JVEL
signal.
When the JVEL signal is OFF, the actuator moves by the value of parameter No. 48, “PIO inching
distance.”
When the JVEL signal is ON, the actuator moves by the value of parameter No. 49, “PIO inching distance
2.”
x The actuator moves at the rated acceleration/deceleration (the specific value varies depending on the
actuator).
During normal operation, the actuator will continue with the normal operation even when the JOG+ or JOG- is
turned ON (= the JOG signal will be ignored).
While paused, the actuator will not move even when the JOG+ or JOG- is turned ON.
(Note) Take note that before completion of home return, the actuator may collide with the mechanical end
because the software stroke limits are not valid.
