Overvoltage
Low voltage
Error
Occurs during
operation.
Occurs when
power supply is
turned ON.
Occurs when Ser-
vomotor is decel-
erating.
Occurs during
descent (vertical
axis)
Occurs when the
control circuit
power supply only
is turned ON.
Occurs when the
main circuit power
supply is turned
ON.
Status when
error occurs
Regenerative energy
exceeds tolerance.
Setting error in Pn600
(regeneration resistor
capacity)
Main-circuit power supply
voltage is outside toler-
ance range.
Main circuit power supply
voltage is outside toler-
ance range.
Main-circuit power supply is
damaged.
Load inertia is too great.
Main circuit power supply
voltage exceeds tolerance
range.
Gravitational torque is too
large.
Control panel error
Main circuit power supply
voltage is outside toler-
ance range.
Main circuit power supply is
damaged.
Cause of error
Calculate the regenerative
energy, and connect an exter-
nal Regeneration Resistor with
the required regeneration
absorption capacity.
Set Pn600 correctly.
Change the main-circuit power
supply voltage to within toler-
ance range.
Change the main circuit power
supply voltage to within toler-
ance range.
Replace the Servo Driver.
Deceleration time is too long.
Calculate the regenerative
energy, and connect an exter-
nal Regeneration Resistor with
the required regeneration
absorption capacity.
Reduce main circuit power
supply voltage to within toler-
ance range.
Add a counterbalance to the
machinery to lower gravita-
tional torque.
Slow the descent speed.
Calculate the regenerative
energy, and connect and exter-
nal Regeneration Resistor with
the required regeneration
absorption capacity.
Replace the Servo Driver.
Change the main circuit power
supply voltage to within toler-
ance range.
Replace the Servo Driver.
