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.
