data error 1
Name: Motor combination error
Combination of servo amplifier and servo motor is incorrect.
Cause
(1) Servo amplifier is
connected to an incorrect
linear servo motor or vice
versa.
(2) Linear servo setting is
selected in the
parameter.
(3) The linear servo motor,
which requires the
parameter No.Po04
setting, is being used.
Name: Encoder initial communication error 2
Encoder is faulty.
Cause
Same as for the rotary servo motor.
Refer to section 8.3.
Name: Encoder initial communication error 3
Connected linear encoder is not compatible.
Cause
(1) Incompatible linear
encoder is connected to
the servo amplifier.
(2) Information in the linear
encoder is incorrect.
Name: Encoder normal communication error 1
Error is found in the communication between the linear encoder and the servo amplifier.
Cause
(1) Encoder cable is faulty.
(2) Fault is generated from
the surrounding
environment.
(3) Servo amplifier is faulty.
