Item Description
Storage details
• During operation with positioning data: The actual target speed, considering the override and speed limit value, etc., is stored.
"0" is stored when positioning is completed.
• During interpolation of position control: The composite speed or reference axis speed is stored in the reference axis address,
and "0" is stored in the interpolation axis address.
• During interpolation of speed control: The target speeds of each axis are stored in the monitor of the reference axis and
interpolation axis.
• During JOG operation: The actual target speed, considering the JOG speed limit value for the JOG speed, is stored.
• During manual pulse generator operation: "0" is stored.
