33.1 Main
circuit
voltage error
(1)
Check the parameter No.
PA02 setting.
Setting is incorrect.
Correct the setting.
Although the regenerative
option is used, the
parameter setting is
incorrect.
Setting is correct.
Check (2).
(2)
Has breakage or
disconnected.
Connect properly.
Lead of built-in
regenerative resistor or
regenerative option has
breakage or
disconnected.
Check the wiring and the
lead of regenerative
resistor (regenerative
option).
Normal. Check
(3).
(3) Check the status of
regenerative resistor
(regenerative option).
Check the resistance.
Regenerative resistor
(regenerative option)
is abnormal.
When using built-in
regenerative resistor,
replace the servo
amplifier.
When using a
regenerative option,
replace the
regenerative option.
Normal.
Check
(4).
(4)
Regeneration
capacity
shortage.
Not reproduced.
Use a regenerative
option if not being
used.
Increase the deceleration
time constant, and check
the reproducibility of the
error.
Reproduced. Check
(5).
(5) Power supply voltage is
high.
Check the input power
supply voltage.
253VAC or more.
Make input voltage
smaller.
