circuit error
Main circuit transis-
tor module error
Servomotor power
line is short-circuited
or grounded be-
tween phases.
Miswiring between
U-phase, V-phase,
W-phase, and
ground.
Servomotor winding
is burned out.
Ambient Servo Driv-
er temperature ex-
ceeds 55°C.
Radiation shield air
convection is poor.
The fan has
stopped.
Operating above
rated output.
Error in the regen-
erative circuit parts.
External Regenera-
tion Resistor is
burned out.
Apart from a short-
circuit between B2
and B3, the external
circuit resistor is not
connected.
Regenerative ener-
gy exceeds toler-
ance.
Setting error in
Pn600 (regeneration
resistor capacity)
Cause of error
Replace the Servo Driver.
Replace the Servo Driver.
Repair the short-circuited
or grounded wire.
Measure the insulation
resistance at the Servo-
motor and, if there is a
short-circuit, replace the
Servomotor.
Correct the wiring.
Measure the winding re-
sistance, and if the wind-
ing is burned out, replace
the Servomotor.
Lower the Servo Driver’s
ambient temperature to
55°C or less.
Mount according to
mounting conditions.
Replace the Servo Driver.
Lighten the load.
Replace the Servo Driver.
Replace the External Re-
generation Resistor.
Correctly connect the ex-
ternal circuit resistor (be-
tween B1 and B2).
Calculate the regenera-
tive energy, and connect
an external Regeneration
Resistor with the required
regeneration absorption
capacity.
Set Pn600 correctly.
