PLUS+1 Compliant KEP 3-Pt Foot Pedal Function Block User Manual
Introduction
The KEP 3Pt Foot Pedal Function Block provides parameters and logic used to integrate a KEP 3Pt Foot Pedal into your application.
•The SnsrPwr input receives the sensor power voltage applied to the pedal sensor. This voltage remains constant.
•The Pedal input receives the voltage output by the pedal sensor. The position of the pedal varies this voltage.
The function block makes ratiometric comparisons of the Pedal and SnsrPwr inputs. This comparison produces Out values that range from ±10000 (±100.00%).
