9. Changing the position counter (by changing PX or PY, or by an active homing
process) may lead the “Output Compare” function to generate unpredictable results.
Note that the software does not check for this and it is the user’s responsibility to
avoid setting the position counters while “Output Compare” is active.

Notes:
In SimplIQ for Steppers output compare performs similarly on all the sensor
types. There is no difference between incremental encoders and other sensors.
SimplIQ differences:
o The frequency limit is 10 kHz. If the frequency restriction is violated, the
amplifier might not crash, but pulse comparison may be aborted.
o No stray pulses appear at back rotation.
o Homing can run normally while output compare is on.
o Compare distance (OC[3]) is not limited to ±32767
o The compare distance (OC[3]) may be ±1.
o The number of issued pulses is not limited to 65535.
