Wiring for Hitachi VFD

[mr-ben]

Hi

How about a wiring diagram for a Hitache VFD model WJ-200. (G3 contr0ller)

Thanks

The following is an educated guess based on available documentation (disclaimer - I don't have a VFD on my system).

Refer to page 208 of the Hitachi (wiring terminals)

Function	Hitachi WJ-200	Masso G3 Controller	Notes
+10V Reference	Terminal H	N/A	Information only
0-10V Speed Control	Terminal O	Spindle Controller - Terminal 1
Logic Ground Reference	Terminal L	Any Masso GND Terminal	Use GND connection from Masso Power Supply
Forward	Terminal 1	See Page 4-16 for details
Reverse	Terminal 2	See Page 4-16 for details

The Forward / Reverse gets a little arbitrary for a number of reasons.

• Are the inputs configured for current source or sink (see page 4-13, this is configurable)
  
• Is forward CW or CCW?
  

To have the Hitachi driver accept the 0-10V speed signal there are a number of software options that have to be set correctly (see page 3-14):

• Multi-speed inputs set to OFF
  
• Operator control set to OFF
  
• Not sure what else is required... (some experimentation required)

Hi Zombie,

Thanks for your comments. I have set up two VFD drives so I am aware of necessity for configuring the drive.

My last machine had a MASSO G2. I was fishing for one of Peter's neat schematics for this drive and the G3.

Piece of mind thing.
