Warning
Control mode switching was executed
from the position control mode to the
speed control mode/torque control mode
while BUSY was turned ON.
Control mode was changed when "Zero
speed" ([Md.108] Servo status) was turned
OFF.
Control mode switching request was
performed by specifying a value outside
the range for "[Cd.139] Control mode
setting".
Control mode switching request was
performed during the control mode
switching.
The mark detection signal setting is
outside the range.
The mark detection data type setting is
outside the range.
When the mark detection data type setting
is not "Optional 2 word buffer memory",
the mark detection data type setting is
outside the range.
When the mark detection data type setting
is "Optional 2 word buffer memory", the
mark detection data buffer memory No. is
outside the range or odd number.
The speed change request is issued
during deceleration stop with JOG start
signal OFF.
(Note-1)
• The JOG speed is exceeded the
speed limit value at start.
(Note-1)
• The new speed value exceeds
the JOG speed limit value when the
speed is changed during JOG operation.
(Note-1): This speed is a value in which
override value is considered
when override function is used.
("[Cd.13] Positioning operation
speed override" is set other than
100[%].)
The manual pulse generator 1 pulse input
magnification is set to 0, 10001 or more,
or negative value.

Operation status at warning occurrence
The control mode is not switched.
(Positioning during operation continues.)
The control mode is not switched.
(Current operation continues.)
Control mode switching request is not
accepted.
All mark detections are not operated.
All mark detections are not operated.
The speed change is not carried out.
• When the speed exceeds the JOG speed
limit, the JOG operation is carried out with
the JOG speed limit value.
• While the speed is limited by the JOG
speed limit value, the "[Md.39] In speed
limit flag" is turned ON.
• When input magnification is set at 10001
or more, or negative value:
Re-set to 10000.
• When input magnification is set at 0: Re-
set to 1.
