(14) Jog+ command/jog- command (JOG+ / JOG-) PLC output signal
These signals are used to operate a positioner operation axis in the command specification mode
under PIO pattern 1 (teaching mode).
These signals are used to start jogging or inching.
When the + command is issued, the actuator moves in the direction opposite home. When the –
command is issued, the actuator moves in the direction of home.
Jogging or inching is specified by a combination of the JOG signal and JISL signal (jogging/inching
switching signal).
[1] Jogging
Jogging is enabled when the jog/inch switching signal (JISL) is “0” (OFF).
While JOG+ is “1” (ON), the actuator moves in the direction opposite home. When the signal
turns “0” (OFF), the actuator decelerates to a stop.
While JOG- is “1” (ON), the actuator moves in the direction of home. When the signal turns “0”
(OFF), the actuator decelerates to a stop.
The operation is set using the following parameter settings:
• Speed:
Defined by parameter No. 26 (PIO jog speed)
• Acceleration/deceleration: Rated acceleration/deceleration (varies according to the actuator)
To stop jogging (cause the actuator to decelerate to a stop), turn the current JOG signal from “1”
(ON) to “0” (OFF) or cause both JOG+ and JOG- to turn “1” (ON).
[2] Inching
Inching is enabled when the jog/inch switching signal (JISL) is “1” (ON).
The actuator moves by the inching distance every time the JOG signal turns from “0” (OFF) to
“1” (ON).
The actuator inches in the direction opposite home when JOG+ is issued, or in the direction of
home if JOG- is issued.
The operation is set using the following parameter settings:
• Speed:
Defined by parameter No. 26 (PIO jog speed)
• Travel distance:
Defined by parameter No. 48 (PIO inching distance)
• Acceleration/deceleration: Rated acceleration/deceleration (varies according to the actuator)
During normal operation, the actuator will continue with the normal operation even after the
JOG+ or JOG- signal is turned “1” (ON) (= the JOG signal will be ignored). Also while the
actuator is paused, the actuator will not operate even after the JOG+ or JOG- signal is turned “1”
(ON) (= the JOG signal will be ignored).
Caution
Exercise caution that the actuator may collide with a mechanical end before the home return is
completed, because the software stroke limits are still not effective during this period.
