Operation status at warning occurrence
• 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
operations stated above.)
The step will not start.
Even if the external command signal is
turned ON, the system will not perform
anything.
The system stops immediately after it
reaches the positioning address.
• The speed change value is controlled as
the "maximum value within the setting
range".
• The "[Md.39] In speed limit flag" is turned
ON.
Teaching is not carried out when the set
value is 0 or 601 or more.
(The set value is automatically reset to "0"
by the Simple Motion module even when a
"0" or "601" or more is set.)
Teaching is not carried out.
