Parameter
2µs / step. 360º angle range in all modes.
Minimum pos. pulse width (@0º) = 16µs (8 LSB; tbd)
Minimum neg. pulse width (@359º) = 16µs (8 LSB; tbd)
Pulse width @0º = 16µs, Pause = 734µs
Pulse width @1º = 18µs, Pause = 732µs
Pulse width @2º = 20µs, Pause = 730µs
………..
Pulse width @359º = 734µs, Pause = 16µs
In case of an error (LOCK = Low), the pulse width is 8 µs (4
LSB), pause = 742µs for all angles.
Incremental ABI interface: 3 pins
