processing
Corrective action
• Short occurred in servomotor power (U,
V, W).
• Correct the wiring.
• Transistor (IPM) of the servo amplifier
faulty.
[Checking method]
Servo error [2032] occurs if power is
switched on after U, V and W are
disconnected.
• Replace the servo amplifier.
• Ground fault occurred in servomotor
power (U, V, W).
• Correct the wiring.
2032 Overcurrent
• External noise caused the overcurrent
detection circuit to misoperate.
• Take noise suppression
measures.
• Lead of built-in regenerative brake
resistor or regenerative brake option is
open or disconnected.
• Replace the lead.
• Connect correctly.
• Regenerative transistor faulty. • Replace the servo amplifier.
• Wire breakage of built-in regenerative
brake resistor or regenerative brake
option.
• For wire breakage of built-in
regenerative brake resistor,
replace the servo amplifier.
• For wire breakage of
regenerative brake option,
replace the regenerative brake
option.
• Capacity of built-in regenerative brake
resistor or regenerative brake option is
insufficient.
• Add regenerative brake option or
increase capacity.
• Power supply voltage is high. • Review the power supply.
2033 Overvoltage
• Ground fault occurred in servomotor
power (U, V, W).
• Correct the wiring.
2034
Communica-
tions error
• Data received from the Motion CPU
faulty.
• Check the connection of
SSCNET
cable.
• Check if there is a disconnection
in the SSCNET
cable.
• There is excessive variation in the
position commands and command
speed is too high from the Motion CPU.
• Check the command speed and
the number of pulses per
revolution/travel value per
revolution of the fixed
parameters.
• Noise entered the commands from the
Motion CPU.
• Check the connection of
SSCNET
cable.
• Check if there is a disconnection
in the SSCNET
cable.
• Check if any relays or solenoids
are operating in the vicinity.
2035
Command
frequency error
• Motion CPU failure • Replace the Motion CPU.
2036
Transmission
error
• Fault in communication with the Motion
CPU.
Any time during
operation
Immediate
stop
• Check the connection of
SSCNET
cable.
• Check if there is a disconnection
in the SSCNET
cable.
