Centroid's offline Intercon conversational programming software comes with a Sentinel parallel port key or USB key. This key requires a driver to be installed in order to work with Microsoft Windows.
Click here to go to the SafeNet web page containing the current Sentinel driver for Windows, then click on "Sentinel SuperPro".
Centroid's consoles no longer include floppy disk drives. Instead Centroid provides USB ports. For a year or so after the change over to USB in 2005, Centroid included a Swissbit "Twist" USB flash drive with each control console. This device works automatically on the Centroid console with Linux, and on any PC running Windows XP. If you wish to use the Swissbit Twist USB drive on a computer running Windows 98, you need to download and install a driver for it.
Click here to go to the Swissbit support page containing the Windows 98 driver.

A utility to calculate optimal spindle speed settings on the Control Configuration screen. These are the settings that match the RPM displayed on the screen to the RPM the inverter is actually commanding.
First note the previous values on the Control Configuration screen, and make two measurements of actual RPM (with a tachometer) vs. the RPM displayed on the screen. For best results make one set of measurements at a low speed (around 10%) and the second set at a high speed (around 90%).
Then run SPINCAL from the command line. Enter the information you collected. SPINCAL will tell you the best new numbers to enter on the Control Configuration screen.
Run SPINCAL with a command line argument of "/?" for instructions.
