Introduction

2 Introduction

This document will explain how to operate a Lenze-AC Tech MC3000 Variable Frequency Drive using

Metasys N2 protocol. It is intended as a serial communications supplement only and will not discuss

normal drive operations. For more information regarding normal drive setup and functionality, refer to the

MC3000 Installation and Operation Manual (M301).

2.1 Metasys N2 Communications

MC3000 drives running N2 protocol act as N2 devices on a Metasys® Network and function as slaves only.

Thus the device communicating with an MC3000 drive must be an N2 master. The communication rate is

9600 bps with 8 data bits, no parity, 1 start bit and 1 stop bit. The bit sequence is as follows:

DATA

START 1 2 3 4 5 6 7 8 STOP
