Manual operation mode
Point
table
Jog operation
Executes an inching operation with the external input signal or communication function,
based on the speed command set with parameters or objects/registers.
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.
