33
Rotation is
reversed.
The Servo Drive is set for
reverse rotation.
If JOG operation is executed and
the direction is the opposite of
the JOG direction, check
whether the Servo Drive is set
for reverse rotation. Also, check
that the feedback signals (A-
phase/B-phase) are not reversed
and that operation is not set for
reverse in the parameters.
Correct the setting for the
direction of Servo Drive
rotation.
34
The CW and CCW pulse out-
put signals are reversed.
Check the wiring for the CW and
CCW pulse output signals.
Correct the wiring.
35
During an origin search the
origin proximity sensor polar-
ity does not match the param-
eter setting (in the PCU) for
the origin proximity input
polarity.
Check the parameter setting and
the sensor polarity.
Correct the parameter
setting.
36
During an origin search, the
origin proximity input wiring is
faulty.
Check the that the origin proxim-
ity input signal in the operating
memory area is turning ON and
OFF.
Correct the origin proxim-
ity input wiring.
37
The positioning
completed signal is
not output or is
delayed. (The next
operation cannot be
started.)
The Servo Drive’s in-position
width set in the PCU parame-
ters is too narrow, and the
axis is not in the in-position
range. (If it is not in the in-
position range, the next oper-
ation cannot be started
because the preceding opera-
tion is not completed.)
---
Increase the in-position
width set in the PCU
parameters.
38
The wiring for the Servo
Drive’s positioning completed
signal is faulty.
Check the that the positioning
completed signal in the operating
memory area is turning ON and
OFF.
Correct the wiring for the
positioning completed
signal.
39
The servo speed reference is
incorrect.
---
Adjust the Servo Drive’s
gain.
40
The axis is not in the in-posi-
tion range due to external
pressure applied when posi-
tioning stopped.
Using the Servo Drive’s monitor-
ing functions, monitor the error
counter and check whether the
axis is in the in-position range.
If positioning is stopped
outside of the in-position
range due to external
pressure, it is possible to
forcibly position in the in-
position range using error
counter reset output.
Doing this, however, will
result in an non-estab-
lished origin state and so
it is necessary to re-
establish the origin by
repeating origin search or
by performing present
position preset.
No.
