counter (Un00C). Reconsider the operating specifica-
tions.

/HWBB2 for the HWBB function
is ten second or more.
Measure the time lag between the /
HWBB1 and

/HWBB2 signals.
The output signal circuits or devices
for /HWBB1 and

Main Circuit Cable
Open Phase
(With the main power
supply ON, voltage was
low for more than 1 sec-
ond in an R, S, or T
phase.)
(Detected when the main
power supply was turned
ON.)
The three-phase power supply
wiring is incorrect.
Check the power supply wiring.
Confirm that the power supply is
correctly wired.
The three-phase power supply is
unbalanced.
Measure the voltage at each phase
of the three-phase power supply. Balance the power supply by chang-
ing phases.
A single-phase power is input
without setting Pn00B.2 (power
supply method for three-phase
SERVOPACK) to 1 (single-phase
power supply).
Check the power supply and the
parameter setting. Match the parameter setting to the
power supply.
