Subject: Suggestion to connect to a Gecko G540

Hi,

 

I’d like to connect my G540 to my KFlop board as elegantly as possible…

 

The following (left most) is the pin out of the G540 DB25 connector with each pin description, in color are possible KFlop connections:

 

Pin 15-22 on KFlop JP7 connector shown in green here, will be used to control the steppers.

Pin 7-14 on KFlop JP7 would be used as 5V tolerant IO 4 inputs and 2 output. I’ll use these via the 12 Pin port of the G540 because all of these are opto isolated.

I’ll probably use Winford breakout board to have a clean control box.

 

When the E-Stop is pressed DB25 Pin 15 signals a fault to KFlop. The real questions I have are regarding the DB25 Pin 14 VFD, Pin 15 Fault and Pin 16 charge pump, what’s my best options. I’d like to hear your suggestions.

 

I’ve attached the G540 schematics in case this helps we don’t miss something.

 

Motor power supply 48V OK

PC power supply 5V , 12V, OK

 

Currently my CNC as 4 stepper motors, an E-Stop NC between Pin 10 and 12 on the 12 pin terminal.

 

I also use Output 1 to switch on/off my router motor via a solid state relay.

1 input for probing, Zeroing the Z axis mostly.

2 input for X0 and X1 hall sensors.

1 input for the other axis home switch (Y and Z).

 

I intend to add an hall effect switch on Y later, may require another input.

 

That’s about it.

 

Thanks in advance,

Yves

I’m just adding the Excel file, much nicer then below.

 

Sorry,
