Error During Establishment of Connection

 

If no connection can be established to the VVVF controller, this may be due to several reasons:

VVVF controller has "old" software

The program "PowerControl32" works only with a VVVF controller software version as from 18.055.01. The software number is indicated on the conntroller board of the VVVF controller and can be displayed on the screen.

 

 In the case of older VVVF controller software versions, the old PowerControl software must be used:

 

·         Full version 18.038.07

·         Demo version with limited functionality 18.053.03

 

Connection cable is not OK

A so-called null modem cable is required for the exchange of data between the laptop and the VVVF controller. This is a cable where the send and receive lines are crossed. The following pins must be wired at least:

 

 

With newer devices a USB interface is present for the connection of the laptop. Here the data communication is then made by a standard USB cable.

Wrong COM no.

Please check if the COM number is set correctly (menu "Options“ ð "Select COM No.“)
