5.5 Messages Displayed during Operation Using the Teaching Pendant
This section explains the warning messages that may be displayed during operation using the teaching pendant.
Code Message
name
Description
112 Invalid data
An inappropriate value was entered in a 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.
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.
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 don’t indicate an operation error or other abnormality.)
202 Emergency stop
This message indicates that an emergency stop has been actuated.
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.
