5.7 Commissioning an encoder with gear factor

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 (numerator), p0433 (denominator), and p0410 (sign).
To ensure that the commutation position can be accurately determined from the encoder
angle, the following applies:
• For resolvers:
• For all other absolute
encoders:
• Where n is the gear factor:
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.
5.8 Parameter reset to factory settings
The factory settings represent the defined original status of the device on delivery.
Resetting the parameters to the factory settings means that all the parameter settings made
since the system was delivered are reset.
