• A sum check error occurred in the
back-up data (reference values) at
the servo amplifier power supply on
in the virtual mode.
• No home position return.
• A communication error between the
servo amplifier and encoder
occurred at the servo amplifier
power supply on.
• The amount of change in encoder
current value during operation holds
the following expression :
"Amount of change in encoder
current value / 3.5[ms] >180° of
motor revolution"
It is always checked after the servo
amplifier power supply on (in both
servo ON and OFF states).
• During operation, the following
expression holds :
"Encoder current value [PLS]
feedback current value [PLS]
(number of bits in encoder enable
range)".
It is always checked after the servo
amplifier power supply on (in both
servo ON and OFF states).
Error cause

Processing Corrective action
• Executed the home position
return in the real mode.
• Check the motor and
encoder cables and executed
the home position return in
the real mode again.
• Check the motor and
(Note-1)
encoder cables.
