DIGITAL COMMAND INPUTS: POSITION
STAND-ALONE MODE DIGITAL POSITION-CONTROL INPUTS
AEV works with motion controllers that output pulses to command position.
These formats are supported:
Step/Direction
Count-Up/Count-Down (CU/CD)
A/B Quadrature Encoder
In Step/Direction mode, a pulse-train controls motor position, and the direction is controlled by a DC level at the Direction input.
CU/CD (Count-Up/Count-Down) signals command the motor to move CW or CCW depending on which input the pulse-train is
directed to. The motor can also be operated in an electronic gearing mode by connecting the inputs to a quadrature encoder on
another motor. In all cases the ratio between input pulses and motor revolutions is programmable.

DIGITAL COMMAND INPUTS: VELOCITY, TORQUE
STAND-ALONE MODE DIGITAL VELOCITY/TORQUE CONTROL INPUTS
AEV works with motion controllers that output pulses to command velocity and torque (current).
These formats are supported:
PWM/Direction
50% PWM
In PWM/Direction mode, a pulse-train with variable duty-cycle controls motor Vel/Trq, and the polarity or direction
is controlled by HI/LO levels at the Direction input. With 50% PWM operation there is a single signal.
A 50% duty cyle produces zero output. Increasing the duty cycle to 100% produces a full-scale output in one direction
and 0% duty cycle produces a full-scale output in the opposite direction.
