Hitachi X200 to G540 - PWM speed control and run

[BloomingtonMike]

Needing a little reassurance on PWM speed control for a Hitachi X200 and a G540.

The way I read this I can connect:
G540 pin7 (ground) to terminal L on the VFD (Analog Ground)
G540 Pin 8 (VFD Output) to terminal "O" on teh VFD (voltage Input)
G540 Pin9 (VFD +10VDC) to terminal H on the VFD (10V Referance)
set A001=01 (analog input as freq source)

Plus I will use a G540 output and a relay to switch P24 and a programable input for Run.

Am I close??

Here are the diagrams.








OUTPUTS: The G540 has two general purpose outputs called OUTPUT 1 and OUTPUT 2 on the MAIN TERMINAL BLOCK. They are at Pos 5 and Pos 6 respectively on the terminal block. These outputs may be used to drive relay coils or for any other purpose. The outputs are rated at 1A and 50VDC maximum. Connect one end of the load to the output and connect the other end of the load to a positive DC voltage. This voltage may be the G540 power supply or it may be a separate power supply having a different voltage.


ANALOG OUTPUT: This is a 0V to +10V opto-isolated analog output intended for use with VFD drives. VFD OUT goes to 0VDC while the G540 is disabled. Connect VFD GND, VFD OUT and VFD +10V to the VFD drive inputs. Make sure the VFD drive positive voltage does not exceed +12VDC. Do not short VFD OUT to any other terminal. Do not reverse polarity to VFD GND and VFD +10V or the G540 may be damaged







Please and Thank you

can anyone confirm this is correct. I want to control my x200 fvd with gecko540/mach 3

NO -- DO NOT WIRE ANYTHING TO ETHEIR OF THESE PINS - NOT NEEDED AND IT WILL SHORT OUT THE HITACHI INTERNAL AND G540 THINGS +10V SUPPLIES TOGETEHR.. G540 Pin9 (VFD +10VDC) to terminal H on the VFD (10V Referance)

MIKE you are very close, yes. i assume g540 has some kind of output that can supply +24v or sink it so you should not need a relay in between for the run command. but I know nothing of this g540 thing.

It looks OK to me, the VFD +10v analogue supply is used to supply the Gecko isolated PWM to Analogue convertor, H,O, & L).
The relay Contact closure is used to switch P24 to the run input terminal.
Presumably BloomingtonMike got it right as that was a year ago!

Hi Mikie,

Were your 3 connections b/w G540 & Hitachi inverter correct in the end?

I have a WJ200 which is nearly identical and wanted to confirm before I power up.
