Warning name Error details and causes
Outside manual pulse The manual pulse generator 1 pulse input
generator input magnification magnification is set to 0, 10001 or more, or negative
range value.
[Operation status at warning occurrence]
• 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.
Outside manual pulse The manual pulse generator speed exceeds "[Pr.123]
generator speed limit value Manual pulse generator speed limit value".
[Operation status at warning occurrence]
• When the speed exceeds the detailed parameter 2
"Manual pulse generator speed limit value", the
manual pulse generator operation is executed
following the detailed parameter 2 "Manual pulse
generator speed limit mode".
• "In speed limit flag" is turned ON while the speed is
controlled with the detailed parameter 2 "Manual
pulse generator speed limit value".
Deceleration/stop speed The speed change request is issued during
change deceleration stop.
[Operation status at warning occurrence]
The speed change is not carried out.
Speed limit value over • Setting speeds
starting/restarting the positioning or when changing
the speed at the positioning
control, either of reference axes or interpolation axes
exceeds the speed limit value.)
• "[Cd.140] Command speed at speed control mode"
exceeds "[Pr.8] Speed limit value" during the speed
control mode.
• "[Cd.146] Speed limit value at torque control mode"
exceeds "[Pr.8] Speed limit value" during the torque
control mode.
• "[Cd.147] Speed limit value at continuous operation
to torque control mode" exceeds "[Pr.8] Speed limit
value" during the continuous operation to torque
control mode.
[Operation status at warning occurrence]
[Position control mode]
• The speed is controlled with the speed limit value.
• "[Md.39] In speed limit flag" is turned ON.
[Speed control mode/Torque control mode/Continuous
operation to torque control mode] The speed is
controlled with the speed limit value. ("[Md.39] In
speed limit flag" is not turned ON.)
M code ON signal ON The M code ON signal is turned ON when the
positioning data is executed.
[Operation status at warning occurrence]
Continues executing the positioning data.
Speed-position switching The switching signal for speed-position switching
(during acceleration) signal control (INC mode) is turned ON during acceleration.
ON [Operation status at warning occurrence]
The operation is continued.
Insufficient remaining At a continuous operation interrupt request, the
distance distance required deceleration stop is not long enough.
[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.)

Remedy
Set the manual pulse generator 1 pulse input
magnification to within the setting range.
Adjust speed of manual pulse generator or
"[Cd.20] Manual pulse generator 1 pulse input
magnification" not to exceed the speed limit
value.
Do not carry out the speed change during
deceleration with a stop command, during
stoppage, or during automatic deceleration with
position control.
Review each speed so that setting speeds do
not exceed the speed limit value.
Normalize the ON and OFF timings of the "M
code OFF request".
Do not turn ON the speed-position switching
signal during acceleration.
Give a request at the position where there is an
enough remaining distance.
