1.3.3 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 Message Description
112 Invalid data An invalid value was input in a parameter.
(Example) 9601 was input as the serial communication speed by mistake.
Input an appropriate value again.
113 Value too small The input value is smaller than the setting range.
114 Value too large The input value is larger than the setting range.
Refer to the actuator specifications or parameter table and input an appropriate value
again.
115 Home return not
completed
The current position was written when home return was not yet completed.
Execute home return again.
117 No movement
data
Target position is not set under the selected position number.
Input the target position first.
11E Unmatched
paired data
The values indicating the magnitude relationship of a pair of data are inappropriate.
(Example) The same value was input in both the parameters for soft limits + and –.
Input 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 input 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 y 800 = 0.025 mm/pulse.
In this case, this message will be displayed if 0.02 mm is input 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 work part. If the actuator misses
the work part, however, the soft limit will be reached and thus this message is displayed.
Change either the target position or positioning band.
122 Multiple axes
connected at
assignment
An address was assigned when multiple axes were connected.
Assign each address only when one axis is connected.
180 Address change
OK
181 Controller
initialization OK
182 Home change all
clear
183 I/O function
changed
These messages are displayed to confirm operation.
(They do not indicate an operation error or other abnormality.)
202 Emergency stop This message indicates that an emergency stop has been actuated. (It does not indicate
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.
