The KTM5900 can replace optical encoders with the incremental ABZ output, e.g. for motor feedback systems. It is suitable for both on-axis and off-axis applications and therefore offers a high level of flexibility in mechanical design due to its very small design.
The KTM5900 has a 12-bit multi-pole pair counter for up to 4096 pole pairs.
The KTM5900 supports versatile output modes including a 36 Mbps SPI absolute angle output, a programmable ABZ quadrature incremental output with up to 65536 edges, a programmable UVW output for up to 256 pole pairs and a PWM output. Other features of the KTM5900 include automatic linear and nonlinear calibration, Z signal calibration, absolute position synchronization for multipole applications, automatic TMR adjustment for orthogonal signal calculation, and programmable operational amplifier gain. Additionally, the KTM5900 features two industry-leading 2MHz 16-bit SAR ADCs to improve performance and precision.
Particular emphasis was placed on functional safety in the KTM5900. There is an 8-bit CRC verification for the SPI transmission of the angle values and many self-diagnosis alarm functions are implemented.
A key advantage of the KTM5900 is its ability to automatically detect non-linear errors during normal operation and correct them with just a press of a button or an SPI command. In addition, the KTM5900 features a 256-point correction table that allows the user to improve absolute accuracy by storing non-linear error corrections from optical encoders in the KTM5900.
Using a single-pole magnet, both the one-button self-calibration and 256-point error correction table can achieve excellent INL ≤ 0.025°.
