PWM
Our PWM mode is defined with the following characteristics :
Supply : 5 to 30Vdc
PWM frequency : 1kHz
Duty cycle : 10 to 90% (special duty cycle range on demand,
for example 5% to 95%, consult us)
Output voltage : Minimum high level = Vcc-2,5Vdc.
PWM output is submitted neither to the delay error Er nor to the angular range extremities distorsion previously presented.
As encoders with numeric communication do, PWM absolute encoders fit in various applications where speed is significant as well as
where there are a lot of electric interferences : unstable subsequent circuitry supply, distance between sensor and subsequent circuitry…
Because encoder’s data are not contained in a voltage level but in a time, data are prevented from interferences.
