Preliminary User Manual UMAX023241 - Version: 1.1 8-63
Both outputs and the various logical function blocks on the unit are inherently independent from one
another but can be configured to interact in a large number of ways with each other.
The different blocks listed above are configured using any CANopen configuration software.
1.2.
Quadrature Encoder Input Function Block
The controller consists of two digital inputs. The two inputs can be configured to measure digital
signals generated by a quadrature Encoder unit.
The AX023241 controller has configuration options for specifying various Quadrature Encoder unit
parameters, such as step count scaler, direction/polarity of rotation, static step count offset and
number of quadrature Encoder pulses per revolution (for speed measurements).
The controller has two inputs for detecting the pulses generated by a quadrature Encoder unit. The
three measurements (step count, direction and speed) are determined using these two input signals.
