Title: Mobus and Durapulse GS3 VFD Help
Post by: vertcnc on January 09, 2014, 11:17:40 PM

I would like to control the GS3 via Modbus. I have the rs485 connected and appears Modbus communicates without error. I having a problem understanding the settings for start reg and # of registers. it appears I can read on the input side on start reg 0 I can read 7 registers. How should the output be setup to control spindle.  I also would like to map the inputs to User DRO's to display RPM, AMPS, Freq. if possible.

Can I do this with some VB scripts or is a Brain required.

Ok, I figured out the address for reading the drive status and displaying the data to userdro's. Still can figure out what address for output. Any help would be appreciated.
