position-encod.
input
 An incorrect input was selected for the
position encoder (MP110.x/MP111.x)
Possible configurations: CC4xx/6 control
loops: X201 to X206
CC 4xx/8 control loops: X201 to X208
CC 4xx/10 control loops: PWM outputs X51
to X56: X201 to X206
PWM outputs X57 to X60: X207 to X210
 Check MP110.x/MP111.x
E130 Position
error too large
<axis>
 Parameter value in MP640.x is too small.
 Defect in the mounting of the position
encoder.
 Incorrect temperature compensation, or
linear or nonlinear compensation.
 Excessive backlash
 Check the parameter value in MP640.x
(maximum position deviation between MC
and CC during operation).
 Check the parameter value in MP720.x
(linear axis error compensation for analog
axes).
 Check the parameter value in MP710.x
(backlash compensation).
 Check the mounting of the position encoder.
 See “Sequence for Finding Errors in the
Control Loop” on page 6 – 62.
