Stand-Alone Mode digital POSITION-CONTROL Inputs
AEV-APV work 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.

Stand-Alone Mode Digital VELOCITY/TORQUE CONTROL Inputs
AEV-APV work 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 cycle 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.
