DELTA TAU ACC-51E 603736-101 High-Resolution Analog Encoder Interpolator Board.The DELTA TAU ACC-51E 603736-101 is a 2-axis 4096x high-resolution analog encoder interpolator board, which serves as an accessory board for the UMAC (Universal Motion and Automation Controller) system of Delta Tau Company. It is a 3U-sized card that can be installed in the same rack as Delta Tau's Turbo UMAC or Macro Station processors.
Functional Features
High-resolution Interpolation: It can increase the resolution of the analog encoder signal by 4096 times, creating 4096 steps per sine wave cycle, enabling high-precision position detection. For example, when used with a 1000-line sinusoidal rotary encoder, there are 4,096,000 discrete states per revolution.
Multi-channel Input: It can be connected to 2 or 4 (optional) sinusoidal or quasi-sinusoidal encoders, receiving the voltage source signals from the encoders with a signal amplitude of 1Vp-p.
High-speed Processing: The maximum input frequency of the sine cycle is approximately 8MHz, corresponding to a maximum speed of about 3.2768 billion steps per second.
Input Selection: The un-terminated or 120Ω input terminal can be selected through jumpers.

Technical Parameters
Encoder Interface: Suitable for analog encoders with sinusoidal or quasi-sinusoidal wave output, and can be connected to 2 axes or 4 axes (depending on the configuration).
Resolution: There are 4096 interpolation steps per sine wave cycle, and different subdivision precisions can be achieved by matching with encoders of different line counts.
Input Signal Characteristics: It accepts a voltage source signal of 1Vp-p, and the maximum input frequency of the sine cycle is 8MHz.
Electrical Characteristics: It is regarded as an axis device in the UBUS backplane of the UMAC, and its memory mapping is similar to that of the ACC-24E 2X type axis card.
Application Scenarios
It is mainly applied in motion control systems that require high-precision position feedback and speed control, such as the position detection of coordinate axes in CNC machine tools, the precise control of robot joint movements, the motion control of precision positioning equipment in automated production lines, and the high-precision positioning of wafer stages in semiconductor manufacturing equipment.
