iC-MH EVAL MH2D

Description

The iC-MH 12-bit angular encoder is a position sensor with integrated Hall sensors for scanning a permanent magnet. The signal conditioning unit generates constant amplitude sine and cosine voltages that can be used for angle calculation. The resolution can be programmed up to a maximum of 4,096 angular increments per rotation. The integrated serial interface also enables the position data to be read out to several networked sensors. And the integrated memory can be written embedded in the data protocol. The incremental interface with the pins A, B and Z supplies quadrature signals with an edge rate of up to 8 MHz. Inter polation can be carried out with maximum resolution at a speed of 120,000 rpm. The position of the index pulse Z is adjustable. The commutation interface with the signals U, V and W provides 120° phase-shifted signals for block commutation. The zero point of the commutation signals is freely definable in increments of 1.875° over 360°. The commutation signals are available for EC motors with 1 and 2 pole pairs. The RS422-compatible outputs of the incremental interface and the commutation interface are programmable in the output current and the slew rate. In conjunction with a rotating permanent magnet, the iC-MH module forms a one-chip encoder. The entire configuration can be stored in the internal parameter ROM with zapping diodes. The integrated programming algorithm assumes writing of the ROM structure.
