Jogging Section 10-2
The direction designation setting when the jogging operation starts (JOG Bit
turns ON) is enabled. Even if the designation is changed during jogging, the
direction will not change.
The settings for the Acceleration/Deceleration Curve Designation Bit, and For-
ward/Reverse Rotation Current Limit Designation Bit when jogging starts
(JOG Bit turns ON) and stops (JOG Bit turns OFF) are enabled.
The speed command value can always be changed during operation. By over-
writing the speed command value, the speed for the jogging operation can be
changed.
The G-series Servo Drives do not support exponential curve designation.
When using a G-series Servo Drive, do not attempt to use an exponential
curve designation.
The SMARTSTEP Junior Servo Drives do not support acceleration/decelera-
tion filters and torque limits. When using a SMARTSTEP Junior Servo Drive,
do not attempt to use an acceleration/deceleration curve designation or for-
ward/reverse torque limit designation.
Note Do not set both the exponential curve designation and S-curve designation to
1 (enabled) in the acceleration/deceleration curve designation. Enabling both
settings may cause a malfunction.

10-2-4 Starting Jogging
Jogging is performed according to the direction designation and speed com-
mand value set in the Axis Operating Output Memory Areas and started when
the Jog Bit turns ON. Execute JOG when the Busy Flag for the corresponding
axis is OFF. If the jogging operation is started while the axis's Busy Flag is
ON, a Multistart Error (axis error code: 3050) will occur and JOG will not be
executed.
If the SERVO UNLOCK, DEVIATION COUNTER RESET, EMERGENCY
STOP, OR DECELERATION STOP command bit is turned ON, the jog com-
mand will be ignored. Be sure that all of these command bits are OFF before
attempting a jog operation.
The jogging operation will continue while the Jog Bit is ON. To enable the
PCU to receive the JOG command correctly, make sure that the Jog Bit
remains ON while the Receiving Command Flag is ON.
