JOG Operation

While the forward JOG operation is on, the motor rotates in the current address increasing direction. While
the reverse JOG operation is on, the motor rotates in the current address decreasing direction.
→ For details on the approximate S-shaped acceleration/deceleration, refer to Section 6.8.
1. Operation
• While the forward JOG operation is on, the motor rotates in the current address increasing direction. When
the forward JOG operation turns off, the motor decelerates and stops.
• While the reverse JOG operation is on, the motor rotates in the current address decreasing direction. When
the reverse JOG operation turns off, the motor decelerates and stops.
• When the ON time of the forward JOG operation/reverse JOG operation is less than 300 ms, the inching
operation, which outputs 1 pulse or 1 user unit, is executed.
• When the ON time of the forward JOG operation/reverse JOG operation is 300 ms or longer, the pulse is
output continuously.
• When the JOG operation for the reverse direction is executed during the forward JOG operation/reverse
JOG operation, the operation decelerates and stops. While the operation is at stop, the READY remains
ON. Then, when the forward JOG operation/reverse JOG operation is turned off, the JOG operation
resumes.

Point
• When the ON time of the forward JOG operation/reverse JOG operation is less than 300 ms, the following
operation is executed.
The FX -1PG outputs pulses corresponding to 1 user unit.

However, the FX
than the feed rate in the machine system setting or combined system setting and the pulse number
required for the travel in 1 user unit is less than 1 pulse.
• When the operation stops at the forward limit/reverse limit, avoiding the limit is possible by the JOG
operation to the opposite direction.
• When the forward JOG operation/reverse JOG operation is turned off and the JOG operation is re-turned
on during the deceleration, the operation decelerates and stops once, and then accelerates again. When
stopped, READY turns on only for an instant.
2. Positioning completion flag
Before and after the JOG operation execution, the positioning completion flag does not change.
