Delta CP2000 Variable Speed Drives: The Photon and The Electron

This guide will show you how to connect the Polar Monitoring Gateway to the Delta Photon and Electron VSD’s, otherwise know as the Solar and Irrigation drives. It will also take you through the setup and parameters required on these specific versions of the CP2000 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 CP2000  Serial Parameters

1. Connect power to the Gateway.
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.

2. Connect RS-485.
Delta CP2000 RS-485 To Polar Gateway

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

3. Final checks
Before you switch on the Gateway and the device make sure you have done everything correctly in the previous steps.
  • Make sure the wiring is secure – no short circuits.
  • Check if the power cables are not loosely wired to the Gateway.
  • Check if the power cables are not loosely wired to the device.
  • Re-check the RS-485 twisted pair cable is correctly wired.
4. Power on the system

Now you are ready to go, you can now switch on the Polar Gateway and the Delta CP2000.  

5. Configure Delta CP2000 Serial Parameters
These systems are slightly different to the standard CP2000 VSD. The main difference beign that the Polar Gateway needs to communicate directly with the PLC on the VSD. The standard communication parameters will not give the required information and it is important to note the default configurations below. 

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