External errors
4002
Servo end error
The in-position signal did not turn ON during the
servo end determination time.
Increase the servo end determination time setting.
4003
Servo ready error
The servo motor ready signal did not turn ON
at
operation start or during operation.
Check the servo motor and encoder cable.
4004
Forward rotation limit, reverse rotation limit error
•
The forward rotation limit 1 (LSF) and reverse
rotation limit 1 (LSR) are ON.
•
The forward rotation limit 2 (FLS) and reverse
rotation 2 (RLS) limit are ON.
•
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.
4005
Software limit error
The current address exceeds the software upper
and lower limits.
•
Correct the target address.
•
Set the current value to within the software limit
range by JOG operation manual pulse generator
input operation.
4006
Servo amplifier EM1 or EM2 is OFF.
Ensure safety and deactivate the forced stop.
4007
ABS error
The current position could not be established.
•
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.
4008
Illegal origin data
The backup data for restoring the absolute position
is illegal.
Execute a zero return.
4009
Encoder error 1
During operation, the variation of the encoder
current value changes as follows:
"Encoder current value variation/1.7[ms]
>
motor
180
°
"
•
Check the servo motor and
encoder cable.
•
Adopt the noise suppression measures as
described in the manual for the servo amplifier.
4010
Encoder error 2
During operation, the following condition occurred:
"encoder current value (encoder unprocessed data)
[PLS]
≠
feedback current value (servo amplifier
internal data) [PLS] (number of encoder valid bits)."
•
Check the servo motor and
encoder cable.
•
To reduce noise, follow the servo amplifier
manual.
4011
SSCNET III communication error
SSCNET III cable communication error
•
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.
4015
STO signal OFF error (Only the MR-J3- BS)
•
Properly connect the STO I/O signal connector.
•
Change the STO cable.
•
Change MR-J3-D05.
•
Change the external device, or review the setting.

Memory error
If this error occurs
after rebooting and initializing the
20SSC-H,
the module needs repair.
Consult your local Mitsubishi Electric representative.
