(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.
(a) 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.)
(b) 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 continue" (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 warnings "Step not possible (warning code: 511)" will occur and the step operation will not be continued if the
"[Md.26] Axis operation status" is other than "Step standby" or the step valid flag is OFF when step start
information is set.
