MELSEC-Q
12 CONTROL SUB FUNCTIONS
[6] Precautions during control
(1) When step operation is carried out using interpolation control positioning
data, the step function settings are carried out for the reference axis.
(2) 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 standing by". (The step operation will be carried
out from the positioning data set in "
Cd.3
Positioning start No.".)
[7] Step function settings
To use the "step function", write the data shown in the following table to the
QD75 using the sequence program. Refer to section [4] "Using the step
operation" for the timing of the settings.
The set details are validated when written to the QD75.
