Acc-51C
2 Channel High-Resolution Interpolator Board
Part Number: 3A0-603680-10x
The Acc-51C C-UBUS Interpolator Accessory is a sine wave input interpolator designed to interface two (optionally four) analog quadrature encoders to Delta Tau Data System’s C-UBUS style devices.
The Acc-51C is a 3U size card that mounts in the same racks as Delta Tau’s CPCI Turbo CPU.
Accepts inputs from two (optionally four) sinusoidal or quasi-sinusoidal encoders and provides encoder position data to the motion processor.
Creates 4,096 steps per sine-wave cycle.
Can accept a voltage-source (1Vp-p) signal from the encoder. A jumper selects between unterminated or 120W input termination.
When used with a 1000 line sinusoidal rotary encoder, there are 4,096,000 discrete states per revolution (128,000 software counts). The maximum calculated electrical speed of this encoder would be 1,400 RPS or 84,000 RPM, which exceeds the maximum physical speed of most encoders.
Has a CPCI connector which allows it to be placed in the same rack as a CPCI Turbo CPU.
