ESCRIPTION
You send 2-channel quadrature signals and ClearPath moves in response.
This mode is great for replacing quadrature driven stepper systems with a
single compact device that costs less and does more.
To get started, select "Quadrature" from the Input Format drop down
menu in the Mode Controls section.
Assert the Enable Input to energize the motor. Then, send quadrature
pulses from an external controller to ClearPath Inputs A and B to
command motion.

UNCTIONS
Enable Input -
Asserting this input energizes the motor shaft.
Input A -
Quadrature A input.
Input B -
Quadrature B input.
Output (HLFB) -
See HLFB section for available modes.
Notes:
•
Input B must lead Input A for CCW motion; Input A must lead
Input B for CW motion.
•
Maximum pulse input frequency = 700kHz per channel
at 50%
duty cycle.
