10.5 Messages Displayed during Operation Using the Teaching Pendant or PC
Software
This section explains the warning messages that may be displayed during operation using the teaching
pendant or PC software.
Code Error name Cause/Action
112 Invalid data An inappropriate value was entered in a user parameter.
(Example) 9601 was entered as the serial communication speed by mistake.
Enter an appropriate value again.
113
114
Value too small
Value too large
The entered value is smaller than the setting range.
The entered value is larger than the setting range.
Refer to the actuator specifications or parameter table and enter an appropriate
value again.
115 Home return non-completion The current position was written when home return was not yet completed.
Execute home return again.
116 Last position data Data already exists in the last position area of the position table when new data
is added.
Clear or delete the current last position data first.
117 No movement data Target position is not set under the selected position number.
Enter the target position first.
11E Paired data mismatch The values indicating the magnitude relationship of a pair of data are
inappropriate.
(Example) The same value was entered in both the parameters for + and – soft
limits.
Enter appropriate values again.
11F Absolute position too small The minimum movement toward the target position is determined by the lead
length of the drive system and resolution of the encoder.
This message indicates that the entered target value is smaller than the
minimum movement.
(Example) If the lead length is 20 mm, the encoder’s resolution is 800 pulses
and accordingly the minimum movement becomes 20 ÷ 800 = 0.025
mm/pulse.
In this case, this message will be displayed if 0.02 mm is entered as the target
position.
121 Push & hold search end
over
The final position in push & hold operation exceeds the soft limit.
This has no negative effect if the actuator contacts the load. If the actuator
misses the load, however, the soft limit will be reached and thus this message is
displayed as a warning.
Change either the target position or positioning band.
122 Multiple axes connected at
assignment
Address was assigned when multiple axes were connected.
Assign each address only when one axis is connected.

These messages are displayed to confirm operation.
(They don’t indicate an operation error or other abnormality.)
201 Emergency stop An emergency stop condition was detected. (This is not an error.)
20A Servo OFF during operation This message indicates that the servo ON signal (SON) was turned OFF by the
PLC while the actuator was moving, and that the servo turned OFF and the
movement was disabled as a result.
