The position error integrator is preset to the absolute error (Pr 13.10 is 1 or 2, and Pr 13.11 is one) otherwise it is set to zero when this parameter is
set to one.
The position controller is disabled and the error integrator is also reset under the following conditions:
1. If the drive is disabled (i.e. inhibited, ready or tripped)
2. If the position controller mode (Pr 13.10) is changed. The position controller is disabled transiently to reset the error integrator.
3. The absolute mode (Pr 13.11) is changed. The position controller is disabled transiently to reset the error integrator.
4. One of the position sources is invalid.
5. The position feedback initialised (Pr 3.48) is zero.
