FC 300 Design Guide

Potentiometer Reference

Voltage reference via a potentiometer.
Reference Source 1 = [1] Analogue input
53 (default)
Terminal 53, Low Voltage = 0 Volt
Terminal 53, High Voltage = 10 Volt
Terminal 53, Low Ref./Feedback = 0 RPM
Terminal 53, High Ref./Feedback = 1500
RPM
Switch S201 = OFF (U)

Encoder Connection

The purpose of this guideline is to ease the set-up of encoder connection to FC 302. Before setting up
the encoder the basic settings for a closed loop speed control system will be shown.
Encoder Connection to FC 302

Encoder Direction

The direction of encoder is determined by which order the pulses are entering the drive.
Clockwise direction means channel A is 90 electrical degrees before channel B.
Counter Clockwise direction means channel B is 90 electrical degrees before A.
The direction determined by looking into the shaft end.
