Cause Investigation and corrective actions
1
■
For motor encoder wiring:
 Improper wiring.

Connector is removed.
 Loose connection.
 Encoder cable is too long.
 Encoder cable is too thin.
■
Check the wiring conditions and
correct it if improper.
■
Confirm that the encoder power
supply voltage at the motor side is
above 4.75 V, correct it if improper.
2
■
Servo amplifier and motor encoder
are not combined properly.
■
Replace with servo motor equipped
with proper encoder.
3
■
Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.

Cause Investigation and corrective actions
1
■
Parameter setting is for full-closed
system.
■
Change the system parameter ID20
to "00:Motor_Enc".
2
■
EN2 is selected as encoder
connector. (In case of that the 8th
digit of servo amplifier model
number (encoder type) is "2".)
■
Change the system parameter ID10
to "00:EN1".
