Homing can be safely carried out in PTP and jog position motion modes. With

PT and PVT modes, the online reloading of the position counter can lead to an
immediate, automatic MO=0 due to an excessive position error.

When the Index or Home signal captures PX, the PY captured value is taken at

the next position controller sampling time (4 TS period). It may differ from the
PY value at the capture time by up to 4*TS*10

-6

*VY counts.

When the Index or Home signal captures PX, the digital output of HM[6] is set

only at the next position controller sampling time (4 TS period).

Negative index polarity should never be used with analog encoders. SimplIQ

will not detect an error but the results may be incorrect.
