Thread: AC servo motor help !
The bigger question is WHY? What benefit will you get adding rs232/485 capability? Seems a lot of work for little return plus the internal software of the VFD may not be configured to use it.
No its not big work because i have PS/2 connector & spare smd parts
i have ordered 10pcs from each ICs (max232 & SP485) from ebay and i have allready found the most parts values.
The manufacturer price for this operation is only 50 cny ( 6 euros )
´®¿Ú¹¦ÄÜ²¹²î¼Û-ÌÔ±¦Íø so i will try to pay him to give me the values of components.
The driver supports rs232/485 with extra 6 euro.
I found manufacturer(perhaps wholesale seller) webpage: cnyfdz.com
Also i have tested the driver with the connection phase -> L1-L2 bridged , neutral -> L3 and works fine with using 2 rectifiers (8 of 8 diodes in the 2 rectifiers).
So this is the proper way to connect this drive in single phase 230VAC next is to measure DC bus for ripple on big electrolytic caps (with default 3 caps)
I want to connect these servos with pc (mach3) and because for first time iam using servos i need some help how to connect them with pc parallel port.
Here is the manual of this drive version 3 (in version 2 a lot of things are wrong/missing)

I found all missing electronic components for rs232 rs485 connection (i have tested the connection with these components and works fine)
D11 S4 signal diode
D12 S4 signal diode
Z1 SMB 6.8CA TVS
Z2 SMB 6.8CA TVS
U22 MAX232 16pins (with MAX232A C65 C66 C70 C67 C68 = 0.1uF)
U35 MAX485 8pins
CN1 PS/2 connector 6pins (The holder for the fuse in L1 line must removed and the fuse must soldered without the fuse holder because there is not enough free space for PS/2 6pins connector)
Also the new version of manual ASDD-30A ( v3.1 )

I am baffled by your mod. Very brave.
Also 2 free programs to set parameters with modbus i have tested and worked fine are qModMaster and qModBus
new manual ASDD-30A v3.4
