The following table provides a description of the auxiliary encoder
interface.
Parameter
Description
Minimum Maximum
ON State
Input Voltage
Input voltage difference between the +
input and the - input that is detected as
an ON state.
+1.0V
+7.0V
OFF State
Input Voltage
Input voltage difference between the +
input and the - input that is detected as
an OFF state.
-1.0V
-7.0V
Common Mode
Input Voltage
Potential difference between an encoder
signal and logic ground.
-7.0V
+12.0V
DC Current Draw
Current draw into the + and - input.
-5mA
5mA
Signal Frequency
Frequency of the AX or BX signal inputs.
Count frequency is 4 times this
frequency for A/B/I type inputs.
—
2.5 MHz
IX Pulse Width,
A/B/I Mode
Pulse width of the index input signal.
Since the index is active for a
percentage of a revolution, the speed
will determine the pulse width.
