Code Error Content
Servo end error
4002 The in-position signal did not turn ON during the
servo end determination time.
Servo ready error
4003 The servo motor ready signal did not turn ON at
operation start or during operation.
Forward rotation limit, reverse rotation limit error
• The forward rotation limit 1 (LSF) and reverse
4004 rotation limit 1 (LSR) are ON.
• The forward rotation limit 2 (FLS) and reverse
rotation 2 (RLS) limit are ON.
Software limit error
4005 The current address exceeds the software upper
and lower limits.
4006 Servo amplifier EM1 or EM2 is OFF.
ABS error
The current position could not be established.
4007
Illegal origin data
4008 The backup data for restoring the absolute position
is illegal.
Encoder error 1
During operation, the variation of the encoder
current value changes as follows:
4009
"Encoder current value variation/1.7[ms]
180°"
Encoder error 2
During operation, the following condition occurred:
"encoder current value (encoder unprocessed data)
4010
≠
[PLS] feedback current value (servo amplifier
internal data) [PLS] (number of encoder valid bits)."
SSCNET III communication error
SSCNET III cable communication error
4011
STO signal OFF error (Only the MR-J3- BS)
4015
9000 Memory error
9001 Sum check error
9002 Watchdog timer error
9003 Hardware error
Increase the servo end determination time setting.
Check the servo motor and encoder cable.
• Check the wiring of the forward/reverse rotation
limit, limit switches and the program.
• Check the external signal selection (positioning
parameter) settings.
• Retract from the forward/reverse rotation limit by
JOG operation or manual pulse generator input
operation.
• Correct the target address.
• Set the current value to within the software limit
range by JOG operation manual pulse generator
input operation.
Ensure safety and deactivate the forced stop.
• Make sure to use a servo motor with absolute
position detection.
• Make sure to use the battery for the servo motor
to retain the origin position.
• Make sure that the absolute position detection
system in servo parameters is valid.
• Check the servo motor and encoder cable.
Execute a zero return.
• Check the servo motor and
encoder cable.
• Adopt the noise suppression measures as
>
motor
described in the manual for the servo amplifier.
• Check the servo motor and
encoder cable.
• To reduce noise, follow the servo amplifier
manual.
• Check the SSCNET III cable connection.
• Wipe off any dirt from the end surface.
• Change the SSCNET III cable.
• To reduce noise, follow the servo amplifier
manual.
• Properly connect the STO I/O signal connector.
• Change the STO cable.
• Change MR-J3-D05.
• Change the external device, or review the setting.
If this error occurs after rebooting and initializing the
20SSC-H, the module needs repair.
Consult your local Mitsubishi Electric representative.
