during deceleration stop.
The speed change is not carried out.
501
Speed limit value
over
The new value exceeds the speed
limit value when the speed is
changed during operation.
• The speed is controlled with the
speed limit value.
• The "speed limiting flag" is turned
ON.
503
M code ON signal

Insufficient
remaining distance
• At a continuous operation interrupt
request, the distance required
deceleration stop is not long
enough.
• At a speed change request, the
remaining distance is shorter than
the distance required for speed
change.
• When a command speed is
changed:
Change to a value as near a new
speed value as possible.
• When a target position is changed:
Adjust the speed to a value as
near the command speed as
possible, and then change to a
target position.
(When the operation pattern is a
continuous path control, ignore the
