Corrective action
• U, V, W in the servo amplifier outputs
have short circuited with each other.
• Check if there is a short circuit
between U, V, W of the servo
amplifier outputs.
• U, V, W in the servo amplifier outputs
have shorted to ground.
• Check if U, V, W of the servo
amplifier outputs have been
grounded to the ground
terminal.
• Check if U, V, W of the
servomotor are grounded to the
core. If grounding is found,
replace the servo amplifier
and/or servomotor.
• Incorrect wiring of U, V, W phases in
the servo amplifier outputs.
• Correct the wiring.
• The servo amplifier transistor is
damaged.
• Replace the servo amplifier.
• Failure of coupling between
servomotor and encoder
• Replace the servomotor.
• Encoder cable failure • Replace the encoder cable.
• A servomotor that does not match the
setting has been connected.
• Check the connected motor in
the system settings.
• The servomotor oscillated. • Check and adjust the gain
setting value in the servo
parameters.
2032 Overcurrent
• Noise entered the overcurrent
detection circuit.
• Check if any relays or solenoids
are operating in the vicinity.
• The converter bus voltage exceeded
400[V] or more. (800VAC or more for
400VAC series servo amplifier.)
• The frequency of
acceleration/deceleration was too
high for the regenerative ability.
• The regenerative resistor has been
connected incorrectly.
• Increase the
acceleration/deceleration time in
the fixed parameters.
• Check the connection between
C and P of the terminal block for
regenerative resistance.
• The regenerative resistor in the servo
amplifier is destroyed.
• Measure between C and P of the
terminal block for regenerative
resistance with a multimeter; if
abnormal, replace the servo
amplifier. (Measure about 3
minutes after the charge lamp
has turned off.)
• The power transistor for regeneration
is damaged.
• Replace the servo amplifier.
2033 Overvoltage
• The power supply voltage is too high. • Measure the input voltage (R, S,
T) with a voltmeter.
2034
Communica-
tions error
• Data received from the Multiple CPU
system is fault.
Any time during
operation
Immediate
stop
• Check the connection of
SSCNET cable.
• Check if there is a disconnection
in the SSCNET cable.
• Check if the SSCNET cable is
clamped correctly.
