error
Servomotor power line is
short-circuited or grounded.
The ambient temperature for
the Driver is higher than 55 C.
The load torque is too high.
The power supply voltage is
outside of the allowable
range.
The load inertia is too large.
The power supply voltage is
outside of the allowable
range.
The external Regeneration
Resistor is damaged.
Gravity torque is too large.
Probable cause
Replace Driver.
Replace Driver.
Bring the ambient tempera-
ture for the Driver down to
55 C or lower.
Calculate the amount of
regeneration and replace the
Regeneration Resistor with
one of the appropriate capac-
ity.
Correct the power line short-
circuiting or grounding.
Measure the insulation
resistance at the Servomo-
tor itself. If there is short-cir-
cuiting, replace the Servo-
motor.
Lighten the load.
Lengthen the acceleration
time.
Select another Servomotor.
The supply voltage must be
170 to 264 VAC when
200 VAC is specified
The supply voltage must be
85 to 127 VAC when
100 VAC is specified.
Lengthen the deceleration
time.
Calculate the regeneration
and select a Regeneration
Resistor.
The supply voltage must be
170 to 264 VAC when
200 VAC is specified
The supply voltage must be
85 to 127 VAC when
100 VAC is specified.
Add a counterbalance to the
machine, and reduce the
gravity torque.
Reduce the lowering speed.
Connect an external Regen-
eration Resistor.
