5.7 Commissioning an encoder with gear factor
Description
When encoders are commissioned (p0010 = 4), a gearbox must be parameterized by means
of parameters p0432 (counter), p0433 (denominator), and p0410 (sign).
To ensure that the commutation position can be accurately determined from the encoder
angle, the following applies:

The encoder commissioning program ensures that this uniqueness condition is observed
and, if necessary, prevents the system from exiting the commissioning program or outputs
an error message.
Sign bit p0410 inverts the calculated encoder angle and the speed, thereby yielding a
negative gear factor.
