It is possible to change a target speed during the JOG operation. The target speed is changed
by rewriting unit memories using a user program.

 Operations of each contact
• The BUSY flags (X30-X33), which indicate that the motor is running, will turn on when the
JOG operation starts, and they will turn off when the operation completes.
• The operation done flags (X34-X37), which indicate the completion of operation, will turn on
when the current operation is completed, and they will be held until the next positioning
control, JOG operation or home return operation starts.
 Characteristics of acceleration/deceleration zone when changing speeds
• The speeds of acceleration zone and deceleration zone changes by approx. 100 us when
changing the speeds in the JOG operation. The speed variation is obtained by the following
formula.
Speed variation = (JOG operation target speed - Startup speed) / (JOG acceleration time or
JOG deceleration time)
• When the JOG acceleration time or JOG deceleration time is set to 0 ms, the speed will be
changed immediately.
