Chapter 13 Control Sub Functions
[2] Step mode
In step operations, the timing for stopping the control can be set. This is called
the "step mode". (The "step mode" is set in the control data "[Cd.34] Step
mode".)
The following shows the two types of "step mode" functions.
(1) Deceleration unit step
The operation stops at positioning data requiring automatic deceleration. (A
normal operation will be carried out until the positioning data requiring
automatic deceleration is found. Once found, that positioning data will be
executed, and the operation will then automatically decelerate and stop.)
(2) Data No. unit step
The operation automatically decelerates and stops for each positioning
data. (Even in continuous path control, an automatic deceleration and stop
will be forcibly carried out.)
[3] Step start information
Control stopped by a step operation can be continued by setting "step continues"
(to continue the control) in the "step start information". (The "step start
information" is set in the control data "[Cd.36] Step start information".)
The following table shows the results of starts using the "step start information"
during step operation.

The next positioning data is executed.
The warning "Step not possible" (warning code: 511) will occur if the "[Md.26]
Axis operation status" is as shown below or the step valid flag is OFF when step
start information is set.
