Encoder Direction; Closed Loop Drive System - Danfoss VLT AutomationDrive FC 300 Design Manual

FC 300 Design Guide

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.

Closed Loop Drive System

"
A drive system consist usually of more elements as:
• Motor
Add
•
(Gearbox)
(Mechanical Brake)
FC 302 AutomationDrive
•
Encoder as feed-back system
•
• Brake resistor for dynamic braking
Transmission
•
Load
•
Applications demanding mechanical brake control will usually need a brake resistor.
