•
During operation, the amount of change in
the encoder current value complies with the
following expression: "Amount of change in
encoder current value/3.5 ms 180
°
of motor
revolution"
After the servo amplifier power has been
turned ON, a continual check is performed
(in both servo ON and OFF states).

•
During operation, the following expression
holds: "Encoder current value (PLS)
≠
feedback current value (PLS) (encoder
effective bit number)".
After the servo amplifier power has been
turned ON , a continual check is performed
(in both servo ON and OFF states).

•
Check the motor and encoder cables.
(4) System Errors (1300 to 1399, 1500 to 1599)
