Error Content
Encoder error 1
During operation, the variation of the encoder
current value changes as follows:
"Encoder current value variation/1.7[ms]
180°"
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)".
SSNET III communication error
SSCNET III cable communication error
Memory error
Sum check error
Watchdog timer error
Hardware error
→For details on how to check errors and actions, refer to the manual of the servo amplifier to be connected.

Sensor fault 2
• Communication error occurred between sensor
and servo amplifier.
Main circuit error
• Ground fault occurred at the servo motor power
(U, V and W phases) of the servo amplifier.
Absolute position erase
• Absolute position data in error
• Power was switched ON for the first time in the
absolute position detection system.
Action
• 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 cable connection.
• Wipe off any dirt from the end surface.
• Change the SSCNET cable.
• To reduce noise, follow the servo amplifier
manual.
If this error occurs after rebooting and initializing the
20SSC-H, the module needs repair.
Consult a Mitsubishi Electric distributor.
