Precautions on Welding
6.1
Error Detection Function
Error detection is performed for the following items, and the welding source 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
Err001
Input over-
voltage
Primary input voltage exceeding
550 V is applied continuously for
two seconds.
Check the input voltage.
Err002
Input under-
voltage
Primary input voltage is lower
than 390 V continuously for two
seconds.
Check the input voltage.
Err102
Excessive
temperature
The temperature in the primary or
secondary control circuit exceeds
the specified value of the welding
source.
• Check the ambient temperature
(40
°
C or less) and operational
ratio (100 %).
• Check if there are dust, dirt, and
clogging on the dust protective
filter. Clean or replace the dust
protective filter if necessary.
Err107
Input/output
overcurrent
Overcurrent flows in the primary
control circuit.
• Check if the output cable is
short-circuited or grounded.
• The power circuit may be bro-
ken. Contact your Yaskawa
representative.
Err110
Voltage
detector error
The welding voltage is not
detected.
Contact your Yaskawa represen-
tative.
Err111
Auxiliary cir-
cuit overcur-
rent
Overcurrent flows in the auxiliary
circuit.
The board may be broken. Con-
tact your Yaskawa representa-
tive.
Err203
and 204
CPU error
A communications error between
the CPU1 and the CPU2 occurs.
The board may be broken. Con-
tact your Yaskawa representa-
tive.
