(5) Control details
• The following drawing shows a step operation during a "deceleration unit step".
• The following drawing shows a step operation during a "data No. unit step".
(6) Control precautions
• When step operation is carried out using interpolation control positioning data, the step function settings are
carried out for the reference axis.
• When the step valid flag is ON, the step operation will start from the beginning if the positioning start signal is
turned ON while "[Md.26] Axis operation status" is "Step standby". (The step operation will be carried out
from the positioning data set in "[Cd.3] Positioning start No.".)
