Program Depends on settings of program language.
Indexer
Rotation
direction
specifying
indexer
Positions to the specified station. Rotation direction settable
Shortest
rotating indexer
Positions to the specified station. Rotates in the shorter direction from the current position.
Manual operation mode
Point
table/
program
JOG operation
Executes a contact input or an inching operation with the RS-422/RS-485 communication function based on
speed command set with parameters.
Manual pulse
generator
operation
Manual feeding is executed with a manual pulse generator.
Command pulse multiplication: select from ×1, ×10, and ×100 with a parameter.
Indexer
JOG operation Decelerates to a stop regardless of the station.
Station JOG
operation
Rotates in a direction specified by the rotation direction decision when the start signal turns on.
Positions to the nearest station where the servo motor can decelerate to a stop when the start signal turns off.
