70.1 Load-side
encoder initial
communication -
Receive data
error 1
(1) A load-side encoder
cable is malfunctioning.
Check if the load-side
encoder cable is
disconnected or
shorted.
It has a failure.
Replace or repair
the cable.
[A]
[B]
[WB]
[GF]
It has no failure.
Check (2).
(2) When you use an A/B/Z-
phase differential output
linear encoder, the
servo amplifier is not
compatible with the
linear encoder.
Check if the servo
amplifier (MR-J4-_-RJ)
is compatible with the
A/B/Z-phase
differential output
linear encoder.
The servo amplifier
is not compatible
with it.
Use a servo
amplifier which is
compatible with it.
[A]
[B]
[GF]
The servo amplifier
is compatible with it.
Check (3).
(3) When you use an A/B/Z-
phase differential output
linear encoder, the
connection with the
linear encoder is
incorrect.
Check if the wiring of
the linear encoder is
correct. (Check if it is
wired to PSEL.)
The wiring is
incorrect.
Wire it correctly.
The wiring is
correct.
Check (4).
(4) The servo amplifier is
malfunctioning.
Replace the servo
amplifier, and then
check the
repeatability.
It is not repeatable.
Replace the servo
amplifier.
[A]
[B]
[WB]
[GF]
It is repeatable.
Check (5).
(5) A load-side encoder is
malfunctioning.
Replace the load-side
encoder, and then
check the
repeatability.
It is not repeatable.
Replace the load-
side encoder.
It is repeatable.
Check (6).
(6) Something near the
device caused it.
Check the noise,
ambient temperature,
vibration, etc.
It has a failure.
Take
countermeasures
against its cause.
70.2 Load-side
encoder initial
communication -
Receive data
error 2
Check it with the check method for [AL. 70.1].
