LS ELECTRIC H100 Variable Speed Drives

This guide will show you how to connect the Polar Monitoring Gateway to the LS ELECTRIC H100 Variable Speed Drive. It will also take you through the setup and parameters required on the LS ELECTRIC H100 to ensure communications to the Polar Gateway.

Steps to follow:

  1. Connect power to the Gateway.
  2. Connect RS-485.
  3. Final checks.
  4. Power on the system.
  5. Configure the LS ELECTRIC H100 Serial Parameters.
 

LS ELECTRIC H100 Connection Setup

1. Connect power to the Gateway.

A. Power the gateway from an external power supply.

Power Polar Gateway

Wire the Polar Gateway to a 12-24 V DC power supply. Connect the positive wire to the positive (+) terminal and the negative (-) wire to the negative terminal.

B. Power the gateway from the VSD.

Wire the Polar Gateway directly to the VSD. Connect the positive wire to the +24V(24) terminal and the negative wire to the (EG) terminal.

2. Connect RS-485.
Polar Gateway RS-485
LsH100 RS-485

Wire the RS-485 cable to allow communication with the Polar Gateway. Connect A+ => S+ and the B- => S-. What is RS-485?

3. Final checks
 Before switching on the Gateway and the device, make sure you have completed all the previous steps correctly.
 
  • Make sure the wiring is secure – no short circuits.
  • Ensure that all connections are secure on the device and the gateway.
  • Re-check the RS-485 twisted pair cable is correctly wired.
  • Check that the A and B are correctly wired to the device.
4. Power on the system

Now you are ready to go, you can now switch on the Polar Gateway and the LS ELECTRIC H100.  

5. Configure LS ELECTRIC H100 Serial Parameters
In order for the Gateway to correctly communicate with the LS ELECTRIC H100 controller, there will need to be some changes made to the communication parameters. 

Note: It is critical to change the default settings to reflect the table below.
