Name Definition
Occurrence
factor
1. " Pr.102 Regenerative brake resistor" setting error
2. Built-in regenerative brake resistor or regenerative brake option is
not connected.
3. High-duty operation or continuous regenerative operation caused
the permissible regenerative power of the regenerative brake
option to be exceeded.
Permissible regenerative
power of the built-in
regenerative brake
resistor or regenerative
brake option is
exceeded.
4. Power supply voltage increased to 260V or more.
5. Regenerative transistor faulty.
2030 30
Regenerative
error
Regenerative transistor
fault
6. Built-in regenerative brake resistor or regenerative brake option
faulty.
1. Small acceleration/deceleration time constant caused overshoot
to be large.
2. Servo system is instable to cause overshoot.
2031 31
Overspeed
Speed has exceeded the
instantaneous
permissible speed.
3. Encoder faulty.
1. Short occurred in servo amplifier output phases U, V and W.
2. Transistor (IPM) of the servo amplifier faulty.
3. Ground fault occurred in servo amplifier output phases U, V and
W.
2032 32
Overcurrent
Current that flew is
higher than the
permissible current of
the servo amplifier.
4. External noise caused the overcurrent detection circuit to
misoperate.
1. Lead of built-in regenerative brake resistor or regenerative brake
option is open or disconnected.
2. Regenerative transistor faulty.
3. Wire breakage of built-in regenerative brake resistor or
regenerative brake option
2033 33
Overvoltage
Converter bus voltage
exceeded 400V.
4. Capacity of built-in regenerative brake resistor or regenerative
brake option is insufficient.
1. SSCNET cable is disconnected.
2. SSCNET cable fault (open cable or short circuit).
3. Noise entered the SSCNET cable.
2034 34
CRC
error
