Generic Spindle interfaces, I/O boards, Misc boards and panels / Wiring an ATC spindle using a PMDX-108-Input
« on: February 24, 2018, 03:42:34 PM »
I'm trying to use a PMDX-108-Input to gather the signals from a Colombo ATC spindle. The 108 board is powered via a ribbon cable from my ESS.
Currently I'm using J2 on the 108 board for my probe and it works perfectly. And J3 will be used for a pneumatic pressure sensor (24vdc).
There are 5 outputs from the spindle, each returning 24vdc when activated.
I tried a couple ways to power the 24vdc sensors on the spindle.
The first way is to power it via a shared 24vdc power supply. 0vdc is connected to <J4 and J4 is the sensor wire from the spindle that carries the signal for a push button tool change (24vdc when the button is pushed). J4 LED is lit at all times. When connecting other sensors to J5 - J8, they are all "ON" regardless of sensor state.
The second way is to power the sensors with a completely independent 24vdc power supply. I connect 0vdc from the PS to <J4 and J4 is the sensor wire from the push button tool change. When I push the button, the LED is lit!!!! Success!!!
However, when I connect 0vdc to <J5 - <J8 and the the other sensors to J5 - J8, J4 - J8 LED's are lit.
I cannot seem to get J4 - J8 to act independently.
Any suggestions on how to use the PMDX-108-Input to do what I'd like it to do?
