Posital’s programmable IXARC encoders feature characteristics such as resolution and communications interfaces, and measurement ranges can be set up through firmware updates, with no need for mechanical changes.
For Posital’s programmable incremental encoders, resolution (anywhere between one to 16384 pulses per revolution), direction and communications interface driver (HTL or TTL) can all be defined through software parameters. In the case of absolute encoders with analog interfaces, their outputs – current or voltage – can be ‘scaled’ so that a predetermined range of mechanical motion (anything from a fraction of a turn to several hundred rotations) can be set span the full electrical output range, significantly improving accuracy for simple analog control systems.
