6.1 Error Detection Function
6 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.

Primary input voltage exceeding
550 V is applied continuously for
two seconds.
Primary input voltage is lower
than 390 V continuously for two
seconds.
The temperature in the primary or
secondary control circuit exceeds
the specified value of the welding
source.
Overcurrent flows in the primary
control circuit.
The welding voltage is not
detected.
Overcurrent flows in the auxiliary
circuit.
A communications error between
the CPU1 and the CPU2 occurs.

Remedy
Check the input voltage.
Check the input voltage.
• 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.
• Check if the output cable is
short-circuited or grounded.
• The power circuit may be bro-
ken. Contact your Yaskawa
representative.
Contact your Yaskawa represen-
tative.
The board may be broken. Con-
tact your Yaskawa representa-
tive.
