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 of the following parameters.
•
The speed is based on the parameter value ON/OFF specified using the Jog Speed/Inching
Distance Change-Over (JVEL) signal.
If the JVEL signal is OFF, the actuator operates according to parameter No.26, “PIO jog
speed”.
If the JVEL signal is ON, the actuator operates according to parameter No.47, “PIO jog speed
2”.
• The acceleration/deceleration conforms to the rate acceleration/deceleration (the specific
value varies depending on the actuator).
• When both the JOG+ and JOG- signals are turned ON, the actuator is decelerated and
stopped.
2) Inching (incremental) operation
The inching operation is available while the JISL signal is turned ON.
One time of ON input gives the actuator a constant amount of movement of the inching distance
set in the parameter.
When the JOG+ is turned ON, the movement is to the opposite of the home and when the JOG-
is turned ON, the movement is to the home.
The operation is performed based on the set values.
• The speed conforms to the value of the parameter ON/OFF specified by the JVEL signal.
If the JVEL signal is OFF, the actuator operates according to parameter No.26, “PIO jog
speed”.
If the JVEL signal is ON, the actuator operates according to parameter No.47, “PIO jog speed
2”.
•
The travel conforms to the value of the parameter ON/OFF specified by the JVEL signal.
If the JVEL signal is OFF, the actuator operates according to parameter No.48, “PIO inch
distance”.
If the JVEL signal is ON, the actuator operates according to parameter No.49, “PIO inch
distance 2”.
• The acceleration/deceleration conforms to the rate acceleration/deceleration (the specific
value varies depending on the actuator).
During the normal operation, even when the “+” Jog Signal or “-” Jog Signal is turned ON, the
normal operation is continued. (The Jog signal is ignored.)
In the pause condition, even when the “+” Jog Signal or “-” Jog Signal is turned ON, the
actuator is not moved.
Note: Because the software stroke limit is disabled before the homing operation, the actuator
might run against the mechanism end. Take the greatest care.
