Limit (oPEE)
This fault code occurs:
1. When the positioning error of a
bigger than Pr.11-51 < Maximum allowable
position-following error>
2. .And when Pr.11-54: Treatment to the large
position control error is set as 1: Fault and ramp to
stop or 2: Fault and coast to stop.

The acceleration/ deceleration
time may not be correct.
Verify if the acceleration/ deceleration time is correct.
Setting value of Pr.11-51 may be
too small.
Verify if the setting value of Pr.11-51 is too small.
The positon control of the motor
drive may not be working properly.
1. Verify if the position control works properly.
2. Verify if the settings of APR bandwidth control and the gain value for the
APR feed forward are correct.
The setting of command curve at
the upper unit during the whole
pulse positioning process may not
be right.
If you set Pr.11-40 =1 (Input from external pulse) or set MI = 90 (
command source switch
and choose 1: Input from external pulse), you need to
verify if the acceleration/ deceleration curve of the pulse given by the upper unit
is correct.
