Alarm No.: 10 Name: Undervoltage
Alarm content
The voltage of the control circuit power supply has dropped.
The voltage of the main circuit power supply has dropped.
Detail
No.
Detail name Cause Check method Check result Action Target
10.1 Voltage drop in
the control
circuit power
(1) The control circuit
power supply
connection is incorrect.
Check the connection
of the control circuit
power supply. It has a failure. Connect it correctly. [A]
[B]
[WB]
[RJ010]
[GF]
It has no failure. Check (2).
(2) The voltage of the
control circuit power
supply is low.
Check if the voltage of
the control circuit
power supply is lower
than prescribed value.
200 V class: 160 V
AC
400 V class: 280 V
AC
100 V class: 83 V AC
24 V DC input: 17 V
DC The voltage is the
prescribed value or
lower. Review the voltage
of the control circuit
power supply.
The voltage is
higher than the
prescribed value. Check (3).
(3) The power was cycled
before the internal
control circuit power
supply stopped.
Check the power-on
method if it has a
problem. It has a problem. Cycle the power
after the seven-
segment LED of the
servo amplifier is
turned off.
It has no problem. Check (4).
(4) An instantaneous
power failure has
occurred for longer
time than the specified
time.
The time will be 60 ms
when [Pr. PA20] is "_ 0
_ _".
The time will be the
value set in [Pr. PF25]
when [Pr. PA20] is "_ 1
_ _".
The time will be 60 ms
when [Pr. PX25] is "_ 0
_ _" and the J3
extension function is
used. The time will be
the value set in [Pr.
PX28] when [Pr. PX25]
is "_ 1 _ _".
An instantaneous power
failure of 15 ms or
longer has occurred on
MR-J4-03A6(-RJ) or
MR-J4W2-0303B6.
Check if the power
has a problem. It has a problem. Review the power.
It has no problem. Check (5).
(5) When a power
regeneration converter
is used, the voltage of
the control circuit power
supply is distorted.
Check if the power
has a problem.
When power supply
impedance is high,
power supply voltage
will be distorted due to
current at power
regeneration, and it
may be recognized as
undervoltage. It has a problem. Review the setting
of "[AL. 10
Undervoltage]
detection method
selection" with the
following
parameters.
[A]: [Pr. PC27]
[B] [WB] [RJ010]
[GF]: [Pr. PC20]
Review the power.
