Home position return by the driver home position return method
Driver home position return method
The stepping driver performs home position return autonomously based on the positioning patterns set on the stepping driver
side. Home position return data is set with the parameters on the stepping driver side.
Driver home position return method cannot be used on anything other than a stepping driver. Refer to the manual of the
stepping driver being used for home position return operations and parameters.
Home position return by driver home position return method
The operation for home position return by driver home position return method is shown below.
Home position return execution
Home position return by driver home position return method is executed using a servo program. (  Page 378 Servo
program for home position return)
Cautions
• If a home position return is started for an axis that is not connected to a stepping driver, a minor error (error code: 1979H)
will occur and the home position return is not executed.
• When a stop cause is detected during driver home position return, home position return operation is stopped. The stopping
operation for when a stop cause is detected depends on the stepping driver. Refer to the manual of the stepping driver
being used for details.
• During driver home position return, the home position return is performed based on the home position return direction of the
parameters on the stepping driver side. Make sure the home position return direction is the same as home position return
direction of the parameters on the stepping driver side.
