Enable Input -
Asserting this input energizes the motor shaft.
Input A -
Asserting this input will make ClearPath continue to servo to its
current position regardless of any changes to the frequency on Input B.
Alternatively, this signal can be used as a home sensor input.
Input B -
This input is connected to a digital signal whose frequency
represents the desired position.
Output (HLFB) -
See HLFB section for available modes.
Notes:
•
A signal frequency on Input B equal to the user-defined
minimum will move the motor to position 0. A frequency equal
to the user-defined maximum will move the motor to position 1.
•
Input frequency range: 20 Hz to 700 kHz.
•
Frequencies between the minimum and maximum will
command positions (proportionally) between position 0 and 1.
•
If there are no transitions on Input B for 50 ms or more, this
will be considered an error condition, and the motor will hold
its current position.
