7.6 Convenient Function to Use during Trial Operation
This section describes some convenient operations that you can use during trial operation.
Use them as required.
7.6.1 Program Jogging
You can use program jogging to perform continuous operation with a preset operation pattern,
travel distance, movement speed, acceleration/deceleration time, waiting time, and number of
movements.
You can use this operation when you set up the system in the same way as for normal jogging
to move the Servomotor without connecting it to the host controller in order to check Servomo-
tor operation and execute simple positioning operations.
Preparations
Always check the following before you execute program jogging.
• The parameters must not be write prohibited.
• The main circuit power supply must be ON.
• There must be no alarms.
• There must be no hard wire base block (HWBB).
• The servo must be OFF.
• The range of machine motion and the safe movement speed of your machine must be con-
sidered when you set the travel distance and movement speed.
• There must be no overtravel.
Additional Information
• You can use the functions that are applicable to position control. However, parameters
related to Command Option Modules in PnB00 and higher are disabled.
• The overtravel function is enabled.
For overtravel, the rotation direction is the direction as viewed from the load end of the Servo-
motor.
• The software limits are disabled.
Program Jogging Operation Pattern
An example of a program jogging operation pattern is given below. In this example, the Servo-
motor direction is set to Pn000 = n.0 (Use CCW as the forward direction).
