8. TROUBLESHOOTING
8 - 15
Alarm No.: 33
Name: Overvoltage
Alarm content
The value of the bus voltage exceeded 400 V DC.
Display Detail name
Cause
Check method
Check result
Action
33.1 Main circuit
voltage error
(1)
The setting value is
incorrect.
Set it correctly.
The setting of the
regenerative resistor
(regenerative option) is
incorrect.
Check the regenerative
resistor (regenerative
option) and [Pr. PA02]
setting.
It is set correctly.
Check (2).
(2)
It is not connected
correctly.
Connect it correctly.
The regenerative resistor
(regenerative option) is
not connected.
Check if the regenerative
resistor (regenerative
option) is connected
correctly.
It is connected correctly. Check (3).
(3) Wire breakage of built-in
regenerative resistor or
regenerative option
Measure the resistance
of the built-in
regenerative resistor or
regenerative option.
The resistance is
abnormal.
When using a built-in
regenerative resistor,
replace the servo
amplifier. When using a
regenerative option,
replace the regenerative
option.
The resistance is normal. Check (4).
(4) The regeneration
capacity is insufficient.
Set a longer deceleration
time constant, and then
check the repeatability.
It is not repeatable.
When using a built-in
regenerative resistor,
use a regenerative
option. When using a
regenerative option, use
a larger capacity one.
It is repeatable.
Check (5).
(5) Power supply voltage
high.
Check the input voltage. It is over 264 V AC.
Reduce the input
voltage.
It is 264 V AC or less.
Check (6).
(6) Something near the
device caused it.
Check the noise,
ambient temperature,
etc.
It has a failure.
Take countermeasures
against its cause.
Alarm No.: 35
Name: Command frequency error
Alarm content
Input pulse frequency of command pulse is too high.
Display Detail name
Cause
Check method
Check result
Action
35.1 Command
frequency error
(1) The command pulse
frequency is high.
Check the command
pulse frequency.
The command pulse
frequency is high.
Check operation pattern.
The command pulse
frequency is low.
Check (2).
(2) Something near the
device caused it.
Check the noise,
ambient temperature,
etc.
It has a failure.
Take countermeasures
against its cause.
Alarm No.: 37
Name: Parameter error
Alarm content
Parameter setting is incorrect.
Display Detail name
Cause
Check method
Check result
Action
37.1
(1)
It is out of setting range. Set it within the range.
Parameter
setting range
error
A parameter was set out
of setting range.
Check the parameter
error No. and setting
value.
It is within the setting
range.
Check (2).
(2) The parameter setting
has changed due to a
servo amplifier
malfunction.
Replace the servo
amplifier, and then check
the repeatability.
It is not repeatable.
Replace the servo
amplifier.
37.2 Parameter
combination
error
(1) A parameter setting
contradicts another.
Check the parameter
error No. and setting
value.
A setting value is
incorrect.
Correct the setting value.
