Multi-Turn Encoder Features
Electronic Reset
 BEI
introduces a multi-turn absolute encoder, the HMT25, with electronic
reset capability. Unlike manual resets (buttons or switches)
an electronic reset can use system software for initialization.
This greatly improves machine set-up time, especially in systems
with space constraints. Sending a timed pulse through the reset
pin, the encoder value gets set to “zero” through
a non-volatile internal memory. Since the encoder uses a geared
multi-turn code wheel system, instead of a battery-dependant
electronic turns counter, the physical position at any time is
precisely determined even in prolonged power down situations.
