1. OVERVIEW OF CONTROLLER
1.1. Description of High Temperature Quadrature Encoder Input Dual Output Valve
Controller
This User Manual describes the architecture and functionality of the High Temperature Quadrature
Encoder Input Dual Valve controller.
Figure 1: Hardware Functional Block Diagram
The High Temperature Quadrature Encoder Input 2 Output controller, later referred as AX023241,
is a highly configurable controller with versatile control of two digital inputs targeted for quadrature
Encoder interfacing and two universal outputs. Its flexible hardware design allows the controller to
have a wide range of output types. The sophisticated control algorithms/logical function blocks allow
the user to configure the controller for a wide range of applications without the need for custom
firmware.
The two digital inputs can be configured to read signals generated by a quadrature Encoder unit.
The inputs are described in more detail in section 1.2.
The two universal outputs can be configured to different types:
Proportional Current, Voltage, PWM,
Hotshot Digital Current and Digital (ON/OFF).
Each output consists of a high side half-bridge driver
able to source up to 2.5Amps with hardware shutdown at 4Amps. The outputs are described in more
detail in section 1.4.
The controller also offers a variety of logical/mathematical functions blocks that can be used to
perform application-specific logic or calculations. These functional blocks are explained in more
detailed in section 1.6 through section 1.8.
