Error Content
→For details on how to check errors and actions, refer to the manual of the servo amplifier to be connected.
Undervoltage
• MR-J3- B:
Power supply voltage dropped to 160VAC or less
• MR-J3- B1:
(10)
Power supply voltage dropped to 83VAC or less
• MR-J3- B4:
Power supply voltage dropped to 280VAC or less
Memory error 1 (RAM)
(12) RAM, memory fault (in servo amplifier)
This error occurs depending on the order with which
the peripheral devices are powered OFF.
(13)
Clock error
• Faulty board
• Clock error transmitted from 20SSC-H
CPU watchdog error
(14) • Servo amplifier hardware error
Memory error 2 (EEPROM)
• EEPROM error (in servo amplifier)
(15) • The EEPROM write count exceeds 100,000
operations.
Encoder error 1 (after power-on)
• Communication error occurred between sensor
(16)
and servo amplifier.
Board error
(17) • CPU/part fault
Memory error 3 (Flash ROM)
(19) • ROM memory fault
Encoder error 2 (during runtime)
• Communication error occurred between sensor
(20)
and servo amplifier.
Encoder error 3 (during runtime)
(21) Error occurred in encoder.
Main circuit error
• Ground fault occurred at the servo motor power
(24)
(U, V and W phases) of the servo amplifier.
Absolute position erase
• Absolute position data in error
(25) • Power was switched ON for the first time in the
absolute position detection system.
Regenerative alarm
• The permissible regenerative power of the built-
in regenerative brake resistor or regenerative
brake option is exceeded.
• Regenerative transistor fault
(30)

Review the power supply
The servo amplifier must be repaired. Consult your
local Mitsubishi Electric representative.
Make sure to Power-OFF the 20SSC-H and the servo
amplifier at the same time or Power-OFF the servo
amplifier before the 20SSC-H.
The direction above does not apply to products
manufactured after June 2006.
The servo amplifier or 20SSC-H must be repaired.
Consult your local Mitsubishi Electric representative.
The servo amplifier must be repaired. Consult your
local Mitsubishi Electric representative.
• Connect correctly.
• Change the servo motor.
• Repair or change the cable.
• Correct the setting of the 4th digit of parameter
No. PC04.
The servo amplifier must be repaired. Consult your
local Mitsubishi Electric representative.
• Connect correctly.
• Change the servo motor.
• Repair or change the cable.
Change the servo motor.
• Correct the wiring.
• Change the cable.
• Change the servo amplifier.
• After leaving the alarm occurring for a few minutes,
switch power OFF, then ON again.
Always create the home position setting again.
• Change the battery.
Always set the home position again.
• Correct the setting of the regenerative brake
option (servo parameter).
• Correctly connect the built-in regenerative brake
resistor or regenerative brake option.
• High-duty operation or continuous regenerating
operation to exceed the permissible regenerative
power of the regenerative brake option.
- Reduce the frequency of positioning.
- Change the regenerative brake option to the
one with a larger capacity.
- Reduce the load.
• Review the power supply
• Change the servo amplifier or regenerative brake
option.
