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”.
However, it will operate in the speed described below in the direct indication mode
when JVEL Signal is on.
When Command Speed Setting = 0 : Operation will be made with a value in Parameter
No. 47 “PIO JOG Speed 2” in MCON.
When Command Speed Setting ≠ 0 : Operation will be made with the setting value in
Command Speed.
• 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.
