Error name
Description
Cause
The power supply voltage is low.
There was an instantaneous control
power failure of 60ms or longer.
Shortage of power supply capacity
caused the power supply voltage to
drop at start, etc. .
Power was restored after the bus
voltage had dropped to 200VDC.
(Main circuit power switched on
within 5s after it had switched off.)

Under voltage
•For MR-J2S-
B:
The power supply voltage dropped
to 160VAC or less.
• For MR-J2S-
B1:
The power supply voltage dropped
to 83VAC or less.
Faulty parts in the servo amplifier.

Memory error 2 EEP-ROM error
Faulty parts in the servo amplifier.
The encoder connecter (CN2) is
disconnected.
Fault in the encoder.
2016
16
Encoder error 1
Communication error occurred
between encoder and servo amplifier.
Encoder cable fault. (Wire breakage
or shot)
2017
17
Board error 2

Memory error 3 ROM memory error.
Faulty parts in the servo amplifier.
2020 1A
Servomotor
combination
error
Wrong combination of servo amplifier
and servomotor.
Wrong combination of servo
amplifier and servomotor
connected.
The encoder connecter (CN2) is
disconnected.
Fault in the encoder.
2020
20
Encoder error 2
Communication error occurred
between encoder and servo amplifier.
Encoder cable fault. (Wire breakage
or shot)
Power input wires and servomotor
output wires are in contact at main
circuit terminal block (TE1).
2024 24
Motor output
side ground fault
Servomotor output (U, V, W phase)
ground fault.
Sheathes of servomotor power
cables deteriorated, resulting in
ground fault.
Voltage low in the super capacitor in
the encoder.
Battery voltage low.
Absolute position data in error.
Battery cable or battery fault.
Servo
amplifier
errors
2025 25
Absolute position
lost
Power was switched on for the first
time in the absolute position detection
system.
Super capacitor of the absolute
position encoder is not charged.
