Outline of operation
• Executes the JOG operation according to the JOG operation parameters specified in the
positioning memory (axis setting area). While the execution condition is valid, the JOG
operation continues.
• The target speed can be changed by rewriting the positioning parameter area with a user
program. The change is executed after it becomes a constant speed.
Precautions during programming
• If an operand is an out-of-range value, an operation error occurs.
• The stop operation has priority when the conditions of system stop, emergency stop, limit
stop and deceleration stop are satisfied.
• An operation error occurs when the system register of a specified channel is other than
“Pulse output [Table operation]”.
• A self-diagnostic error (positioning operation error) occurs when the set value or the value of
the positioning memory (axis setting area) is abnormal.
• The JOG operation needs to be stopped for switching between the forward rotation and
reverse rotation.
• In case of changing a speed, when the target speed after the change is an out-of-range
value, the speed change is not executed and the operation continues.
