Sorry to bother you with this.
I am WAY out of my element, and i'm afraid that i'll fry something, if i don't consult the experts in here
I have ordered a second hand OMRON Varispeed V7 1.5KW 400v AC 3 Phase VFD Inverter Drive (CIMR - V7AZ41P5), to run my drill press
The VFD has a digital potentiometer on the front, but i would like to have the frequency control on an external analog potentiometer.
But going through the manual, i don't even know which potentiometer(how many K-Ohms)to order.
I have gather that i have to connect the three legs of the potentiometer to the FS, FR and FC (Frequency setting power supply (FS), Frequency Reference input (FR)and Frequency reference common (FC), where the variable end of the pot (middle leg) has to go to FR.
The "frequency setting power supply" (Called FS) is 20 mA at 12v. But the Frequency reference ned 0 to +10v?
Also In the manual under the parameters for the FR it says 0 to 10VDC 20K-Ohm, but then in the normal wiring diagram, and the diagram describing the frequency reference, it has an illustration showing 2K-ohm.
I'm sure this is very basic for at lot of you, but for me, it's like staring at the green vertical lines on the screen in the matrix .
I have attached pictures of what i have gathered are the relevant places in the manual, but if not here is the link to the complete manual:
http://www.tecdriver.com.br/arquivos/VARISPEED V7 (CIMRV7) OMRON.pdf
Could anyone please tell me what potentiometer (and maybe additional resistors??)i should buy, and how to hook it up, so i dont fry anything.
I have a pretty good idea which parameters to change in the menu, so it's just how i should physically hook the pot up, and which to buy.
Thanks .
