VCC 4-15V Feedback circuit has to be powered 50 ms before driving, and
until actuator has stopped moving
Current Maximum 15mA @10kΩ and 1nF load.
See diagram.
HALL A/B TState is minimum 5ms in all states
(11,10,00,01)
Duty cycle Hall A 30-70%
Duty cycle Hall B 30-70%
Low level <GND+0.5V @10kΩ and 1nF load
High level >VCC-0.5V @10kΩ and 1nF load
Driving out, the Hall B signal will go high when
Hall A signal is low.
Driving in, the Hall A signal will go high when
Hall B signal is low.w
Resolution The feedback system gives 16 state shifts per
spindle turn.
3 mm pitch => 0.1875 mm per shift
4 mm pitch => 0.25 mm per shift
On 100 mm stroke you will have the following number of pulses:
3 mm pitch => 533 shifts
4 mm pitch => 400 shifts
