Precautions during control
• 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.".)
