Program JOG Operation (Fn004)

The program JOG operation is a utility function, that allows continuous operation determined by the preset
operation pattern, movement distance, movement speed, acceleration/deceleration time, waiting time, and
number of times of movement.
This function can be used to move the servomotor without it having to be connected to a host controller for the
machine as a trial operation in JOG operation mode. Program JOG operation can be used to confirm the oper-
ation and for simple positioning operations.
(1) Preparation
The following conditions must be met to perform the program JOG operation.
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
• The main circuit power supply must be ON.
• All alarms must be cleared.
• The servo ON signal (/S-ON) must be OFF.
• The travel distance and speed must be set correctly considering the machine operation range and safe opera-
tion speed.
• There must be no overtravel.
(2) Additional Information
• The program JOG operation is carried out in position control. However, the pulse reference input to the
SERVOPACK cannot be used.
• The functions that are applicable for position control, such as position reference filter, can be used.
• The overtravel function is enabled in this function.
• When using an absolute encoder, the SEN signal needs not be input since it is always enabled.
• The reference pulse input multiplication switching function is disabled.
(3) Program JOG Operation Patterns
The following describes an example of program JOG operation pattern. The following example is given when
the rotating direction of the servomotor is set as Pn000.0 = 0 (Forward rotation by forward reference).

Run Status
Note: When Pn536 (number of times of program JOG movement) is set to 0, infinite time operation is enabled. To stop
infinite time operation, press the JOG/SVON Key of digital operator to turn OFF the servomotor power.
