Name Description
Error check
Error
processing
Corrective action
• There is excessive variation in the
position commands and command
speed is too high from the Multiple
CPU system.
• Check the command speed and
the number of pulses per
revolution/travel value per
revolution of the fixed
parameters.
2035 Data error
• Noise entered the commands from
the Multiple CPU system.
• Check the connection of
SSCNET cable.
• Check if there is a disconnection
in the SSCNET cable.
• Check if the SSCNET cable is
clamped correctly.
• Check if any relays or solenoids
are operating in the vicinity.
2036
Transmission
error
• Fault in communication with the
Multiple CPU system.
• Check the connection of
SSCNET cable.
• Check if there is a disconnection
in the SSCNET cable.
• Check if the SSCNET cable is
clamped correctly.

(Note-1)
DRU
parameter
adjustment
error
• DRU parameter No.2 or 23 setting
differs from other servo amplifiers.
• Set the DRU parameter correctly.
2042 Feedback error • Encoder signal fault. • Replace the servomotor.
2045 Fin overheating
• The heat sink in the servo amplifier is
overheated.
• Servo amplifier error (rated output
over)
• Power repeatedly turned on/off during
overload.
• Cooling fault
• If the effective torque of the
servomotor is high, reduce the
load.
• Reduce the frequency of
acceleration/deceleration.
• Check if the servo amplifier's fan
has stopped. (MR-H150B or
higher)
• Check if the passage of cooling
air is obstructed.
• Check if the temperature inside
the panel is too high (range: 0 to
+55[
°C] (32 to 131[°F])).
• Check if the electromagnetic
brake was actuated from an
external device during
operation.
• Replace the servo amplifier.
• The servomotor is overloaded. • If the effective torque of the
servomotor is high, reduce the
load.
• The servomotor and regenerative
option are overheated.
• Check the ambient temperature
of the servomotor (range: 0 to
+40[
°C] (32 to 104[°F])).
2046
Servomotor
overheating
• The thermal protector incorporated in
the encoder is faulty.
Any time during
operation
Immediate
stop
• Replace the servomotor.
