List of Warning Codes
Warning
code Warning
name Cause and description Action
0900H Start during
operation The start request has been performed while the axis is in
BUSY state.
[Operation of when the warning has occurred]
The operation is continued. Do not perform the start request while the axis is in BUSY
state.
0901H Deviation
counter clear
request The deviation counter clear has been requested while the axis
is in BUSY state.
[Operation of when the warning has occurred]
The deviation counter clear request is ignored. Do not request the deviation counter clear while the axis is in
BUSY state.
0902H Restart not
possible The restart command has been performed when the axis
operation status is not Stopped.
[Operation of when the warning has occurred]
The operation is continued. Perform the restart command when the axis operation status
is stopped.
0903H Teaching in
BUSY The teaching has been requested while the axis is in BUSY
state.
[Operation of when the warning has occurred]
An error occurs in the axis that is subject to the teaching. Request the teaching when the axis is not in BUSY state.
0904H Less than
speed 1 The speed changed with the override function became less
than 1 in the unit that is currently set.
[Operation of when the warning has occurred]
The operation is controlled at the speed of 1. Set a value for the override function so that the changed
speed becomes 1 or more in the unit that is currently set.
0905H PLC READY
ON write The write request to the flash ROM has been performed while
PLC READY signal [Y0] is on.
[Operation of when the warning has occurred]
Data is not written to the flash ROM. Perform the write request to the flash ROM while PLC READY
signal [Y0] is off.
0906H Illegal override
value A value other than 0 to 300 is set in [Cd.13] Positioning
operation speed override.
[Operation of when the warning has occurred]
The speed is changed as 300 is set. Correct the value within the setting range. For details, refer to

Page 473 [Cd.13] Positioning operation speed override.
0907H Outside new
torque value
range The value set in [Cd.22] New torque value is greater than the
value in [Pr.17] Torque limit setting value.
[Operation of when the warning has occurred]
The torque is controlled with the value in [Pr.17] Torque limit
setting value. Set the value equal to or smaller than [Pr.17] Torque limit
setting value to [Cd.22] New torque value.
For details, refer to the following.

0908H Below bias
speed The value in [Da.8] Command speed is smaller than the value
in [Pr.7] Bias speed at start.
[Operation of when the warning has occurred]
The positioning is performed at the speed of [Pr.7] Bias speed
at start. Correct the values in [Da.8] Command speed/[Pr.7] Bias
speed at start so that the command speed is equal to or
greater than the bias speed at start.
For details, refer to the following.

0909H Analysis mode
change in
BUSY The value in [Cd.43] Analysis mode setting has been changed
while the axis is operating.
[Operation of when the warning has occurred]
The change of [Cd.43] Analysis mode setting is ignored. Do not change the value in [Cd.43] Analysis mode setting
when the axis operation status is not Standby.
090AH PLC READY
ON read The read request from the flash ROM has been performed
while PLC READY signal [Y0] is on.
[Operation of when the warning has occurred]
Data is not read from the flash ROM. Perform the read request from the flash ROM while PLC
READY signal [Y0] is off.
090BH Restart not
possible The restart command has been performed in pre-analysis
mode.
[Operation of when the warning has occurred]
The positioning does not restart. Do not perform the restart command in pre-analysis mode.
(The warning code: 0902H is recognized prior to 090BH.)
0980H Speed change
during
deceleration The speed change has been requested while the operation is
decelerating to a stop by turning off of the JOG start signal.
[Operation of when the warning has occurred]
The speed is not changed. Do not change JOG speed while the operation is decelerating
by turning off of the JOG start signal.
