4.4.6 Encoder
This software module manages the evaluation and monitoring of the encoder signals.
The following encoder types can be evaluated:
Maximum input frequency and maximum speed
The maximum input frequency is related to the electrical input signal. This value has ef-
fect on the maximum evaluatable speed of the drive, which is possible depending on the
number of pulses.
Incremental encoder:
Example: Sine-Cosine encoder with a number of pulses 1024:
Resolver
The theoretical maximum speed is limited due to the excitation frequency (7.8125 kHz)
and the number of pole pairs at a resolver.
Example: Resolver with 1 pole pair
