Tolerant encoder monitoring with SMC30

Features
As of firmware version 2.6, the SMC30 module (code at end of order number -CA2) offers
the following additional functions for evaluating encoder signals:
● Hardware filter
● Optional zero mark
● Parameterizable rotor position adaptation
● Freeze speed raw value.
● Greater compatibility with older encoder types, including third-party encoders.
Two additional parameters (p0437 and r0459) have been added for the new range of SMC
functions.
r0458.12 = 1 indicates whether the extended sensor properties are supported.
Note
The encoder monitoring functions must be parameterized when the encoder is
commissioned, and they can only be parameterized via the expert list. The encoder
monitoring parameters cannot be changed while the drive is running!
The available SMC functions, which are described below, also apply to the internal encoder
evaluation in CU310 and CUA32.

Encoders can have zero marks in any position. Different lengths of zero mark can also be
configured.
When an encoder disk is dirty, the drive should add the missing pulses on the basis of the
zero mark repetitions. If EMC interference causes too many pulses to be added, these
will be subtracted again every time the zero mark is crossed.
