Name Definition
Occurrence
factor
1. Power supply voltage is low.
2. An instantaneous power failure occurred for 60ms or longer.
3. Shortage of power supply capacity caused the power supply
voltage to drop at start, etc.
4. Power was restored after the bus voltage dropped to 200VDC.
(Main circuit power switched ON within 5s after it had switched
OFF.)
2010 10
Undervoltage

incorrectly.
Servo amplifier and servomotor were connected in incorrect
combination.
1. Encoder connector (CN2) disconnected.
2020
20
Encoder error 2
Communication error
occurred between
encoder and servo
amplifier.
2. Encoder cable faulty (open cable or short circuit)
1. Power input cable and servomotor output cable are making
contact at the main circuit terminal block (TE1).
2024 24
Ground
fault
Ground fault occurred at
the servomotor outputs
(U, V and W phases) of
the servo amplifier.
2. Servomotor power cable insulation deteriorated.
1. Reduced voltage of super capacitor in encoder
2. Battery voltage low
Absolute position data in
error
3. Battery cable or battery is faulty.
2025 25
Absolute
position erase
Power was switched ON
for the first time in
absolute position
detection system.
4. The super capacitor of the absolute position detector is not
charged.
