  • Page 5: Overview

    The Encoder Module can use High-voltage Transistor Logic (HTL) and Transistor Transistor Logic (TTL) digital encoders. When the Encoder Module is fitted to the MICROMASTER 440 it allows closed-loop encoder feedback with the following benefits in comparison to Sensorless Vector Control (SLVC) and Variable Frequency (V/f) operation...

  • Page 6: Installation

    3.1.1 Preparation of the Inverter Caution The Encoder Module will only function with the MICROMASTER 440 inverters and must have Version 2.0 or above software installed. The version level of software install in the inverter can be confirmed by using one of the following procedures: By accessing parameter r0018 which displays the current software version number.
