Probable causes
The Servo Drive is set for
reverse rotation.
The CW and CCW pulse
output signals are reversed.
During an origin search the
origin proximity sensor
polarity does not match the
parameter setting (in the
PCU) for the origin proximity
input polarity.
During an origin search, the
origin proximity input wiring is
faulty.
The Servo Drive's in-position
width set in the PCU
parameters is too narrow,
and the axis is not in the
in-position range. (If it is not
in the in-position range, the
next operation cannot be
started because the
preceding operation is not
completed.)
The wiring for the Servo
Drive's positioning completed
signal is faulty.
The servo speed reference is
incorrect.
The axis is not in the
in-position range due to
external pressure applied
when positioning stopped.
Items to check
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.
Check the wiring for the CW
and CCW pulse output signals.
Check the parameter setting
and the sensor polarity.
Check the that the origin
proximity input signal in the
operating memory area is
turning ON and OFF.
---
Check the that the positioning
completed signal in the
operating memory area is
turning ON and OFF.
---
Using the Servo Drive's
monitoring functions, monitor
the error counter and check
whether the axis is in the
in-position range.
Section 11-1
Remedy
Correct the setting for
the direction of Servo
Drive rotation.
Correct the wiring.
Correct the parameter
setting.
Correct the origin
proximity input wiring.
Increase the in-position
width set in the PCU
parameters.
Correct the wiring for the
positioning completed
signal.
Adjust the Servo Drive's
gain.
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
unestablished origin
state and so it is
necessary to
re-establish the origin by
repeating origin search
or by performing present
position preset.
