In my projects for upgrading CNC machines on a Kflop board, I sometimes use analog Sine / Cosine encoder interpolators with 11mA or 2Vpp output to the RS-422 quadrature differential standard. The index label is also processed.
The interpolator is made on a specialized microcontroller. He supports:
- Input frequency of up to 700 kHz
- AB output frequency of up to 12.5 MHz
- Automatic compensation of amplitude, offset, and phase errors
- Digital filtering for ultra-low output jitter
- fault monitoring capabilities
- Push-button automatic calibration for fast commissioning
- 10-bit ADCs convert the conditioned analog sin and cos signals into digital values for further processing. An 8-bit ADC is used for the zero signal
- interpolation factor 5, 10, 20, 25, 40, 50, 80, 100, 125, 180, 200, 250
Mount DIN rail.
This is an analogue of the HEIDENHAIN converter of the ЕХЕ series, only on a modern specialized micro controller and is cheaper.
The interpolator is calibrated for a specific sensor and conditions of use. The procedure is very simple and is performed once upon connection.
I can make Kflop users interpolators to order. The cost of 100 dollars a piece.
Delivery of DHL, FedEx, etc.
P.S. I have been using Kflop in my projects for about 6 years. I have my YouTube channel: https://www.youtube.com/user/UkrainetsA ... subscriber
