Re: Inverter Drives

I have used the FM100 drives before and they are a good value for the
money. You can get them for a good price from
www.dealerselectric.com. Ask for Harold.

You shouldn't have any problem controlling the drive from a PC. You
can program multiple digital inputs to preset speeds, you can use an
analog input for continuous speed control, or you can use the RS232
port. Note that the RS232 drivers are not part of the drive as it
also supports RS485.

You can get the RS232 programming kit for about $50 which includes a
special cable with RS232 drivers and software. It definitely makes
setting up the drive easier and I would highly recommend it if you
are going to set up more than one drive.
