Kfop+Kstep loosing steps

[ltran2000]

I am setting homing right now, seem work ok, I need hexagon bit # 168,169,170 to set limit switch since I can't enter these bits through Kmotion. Thanks

Hi Iran2000,

That bug has been fixed in test version

or the values in hex for 168, 169, 170 are a8, a9, aa.

Hi Tom,
All my spindle relay, homing/limit switches work perfectly for Kflop+Kstep,
now I need wiring diagram for spindle relay for kflop to use with Gecko drives.Thanks

Hi Itran2000,

KFLOP itself only has LVTTL inputs. Some with series 47 ohms to make them +5V tolerant. JP4 and JP5 each have 8 with 150 ohm pull down resistors (all others are high impedance).

So depending on your limit switches you will basically need to come up with an interface to 3.3V LVTTL IO.

There are 3rd party modules that can convert 24V limit switches to 5V signals and provide opto isolation (such as opto22 modules).

If you don't require opto isolation a series ~500 ohm resistor to one of the JP4/JP5 inputs with the internal 150 ohm pull down resistor switched to +12V can work. A 0.1uF ceramic capacitor from the input to ground can add filtering if required.

For relay outputs, Winford sells a 4 output low cost relay board that the KFLOP ouputs can drive.

Otherwise solid state relays that accept a 3V input can also be used.


If you come up with a wiring diagram we can check it for you.

Hi Tom
I am ok with limit/homing switches, I need wiring diagram for spindle relay
output, I would prefer to use solid state relays that accept a 3V input,Thanks

Hi Itran2000,

What will you be switching on your Spindle? The main power? Or just enable and direction? At what voltages and currents?

[ltran2000]

I know how to set enable and direction, I just need how to hook up solid state relay that accept 3V input to what pin on kflop, my spindle is 220v-10a

Hi Tom
I think I know how to set spindle relay output for Kflop+gecko, I use bit 0, and relay(-) to gnd and relay(+) to JP7 pin 7, how much load can this pin output, otherwise I will use opto 4n35.

Hi Itran2000,

That sounds correct. Pin7 (all the KFLOP IO without pull downs) can source 16ma.
