  • Page 7: Chapter 1 - Overview

    General The Master/Follower Application macro is designed for applications in which the system is run by several ACS 600 drives and the motor shafts are coupled to each other via gearing, chain, belt etc. Thanks to the Master/Follower macro the load can be evenly distributed between the drives.

    Chapter 1 – Overview Checklist for a The installation and start-up procedure of the ACS 600 is explained in the Start-up Guide and the Hardware Manual . An additional checklist for the Quick Start-up Master/Follower application is given below: Switch off the power supplies of the ACS 600 units. Wait for five minutes to ensure that the intermediate circuits are discharged.

  • Page 9: Chapter 2 - Installation And M/F Link Specification

    Wait for five minutes to ensure that the intermediate circuit is discharged. Switch off all dangerous voltages connected from external control circuits to the relay output terminals of the ACS 600. WARNING! Do not touch the printed circuits. They are extremely sensitive to electrostatic discharge.

  • Page 18: Follower Supervision

    Chapter 3 – Operation Follower Supervision There are two analogue outputs and three relay outputs in the ACS 600 for the external supervision purposes. By default, analogue output AO1 gives the motor speed and AO2 the motor current as 0 to 20 mA current signal.

    Control settings and Follower Torque Control settings are given in Appendix B – Parameter Settings. Control Connections The parameter values can only be altered with the ACS 600 stopped. 10.01 EXT1 This parameter defines the source of Start, Stop and Direction STRT/STP/DIR commands for External control location 1 (EXT1).
