14 02 Regenera-
tion Circuit
Error
Detected
during Power
ON
*1
An error of the Regener-
ation Circuit was
detected at power ON.
• Power supply voltage
is insufficient at power
ON, or rising slowly.
• Power supply voltage
fluctuated at power
ON.
• L1, L2, and L3 termi-
nals are not con-
nected or
disconnected.
• N1 and N2 terminals
are opened.
Cut off the main circuit power sup-
ply immediately and check whether
charge lamp is turned ON/OFF.
If the charge lamp is turned OFF,
remove the wiring and make the fol-
lowing check.
• Check whether there is an abnor-
mality in the appearance of the
Servo Drive, and that the wiring is
properly done.
• Check that the resistance value
and the power of the External
Regeneration Resistor is correct.
• Wait until the voltage between P
and N1 goes to less than 1 V to
check the resistance value
between P and N1. (If it is less
than 10 kΩ, replace the Servo
Drive.)
• Wait until the voltage get stable to
check the resistance value
between B2 and N1. (If it is less
than 100 kΩ, replace the Servo
Drive.)
• Check whether fluctuation in the
power supply voltage or power
supply occurs or not. (Make sure
that an instantaneous power drop
does not occur, and that the
power rise time is 500 ms or
shorter.)
If the charge lamp is turned ON,
check whether fluctuation in the
power supply voltage or power sup-
ply occurs or not. (Make sure that
an instantaneous power drop does
not occur, and that the power rise
time is 500 ms or shorter.)
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
03 Inrush Cur-
rent Preven-
tion Circuit
Error
*2
An error of inrush cur-
rent prevention circuit
was detected.
Servo Drive failure If this event occurs again, replace
the Servo Drive.
Error No.
