Precautions on Welding
6.1
Error Detection
Error detection is performed for the following items, and the welder is automatically stopped
when an error is detected.
If an error occurs, the "Warning" lamp lights or blinks and the error number is displayed in the
digital meter on the panel face. For the contents of errors, refer to the following table.
At error detection, an arc failure signal is output at the robot side.

Remedy
Err0
System reset
System reset status
Status display at system reset.
This is not a fault.
Err1
Input overcurrent
Overcurrent flows in the
primary control circuit.
The power circuit may be broken.
Contact your Yaskawa representative.
Err2
Output overcurrent
Output overcurrent flows
in the secondary control
circuit.
Check that the torch or power cable is
grounded.
Err3
Input overvoltage
Primary input voltage
exceeding 480V: more
than 570V is applied
continuously for 2
seconds.
Check the input voltage.
Err4
Excessive
temperature
The temperature in the
primary or secondary
control circuit exceeds
the specified value of the
welder.
Check the ambient temperature (40
°
C or
less) and operational ratio (80%).
Err5
Input undervoltage
Primary input voltage is
480V: lower than 390V
continuously for 2
seconds.
Check the input voltage.
Err8
Improper model
setting
Nonconformity in the
model setting of
hardware and software
The setting of hardware or software may
not be performed correctly.
Contact your Yaskawa representative.
Err9
Improper system
reset setting
PR(CR)-002 DIP switch
is not correctly set.
Check the DIP switch setting.
Err10-1
Improper feeding
amount
There is a certain
difference between the
feeding amount
command value and the
feedback from the
encoder.
Check that the encoder cable of the
feeder is not disconnected or that the wire
load is not excessively heavy.
Err10-2
Motor overcurrent
Overcurrent flows in the
motor circuit.
Check that wire load is not excessively
heavy.
Err11
Communications
error
A communications error
between the CPU1 and
CPU2.
The board may be broken.
Contact your Yaskawa representative.
