Hi Tom Can I use absolute encoders with kanalog?, I have a cnc machine equipped with a C axis rotary spindle, but i guess that servo motor uses absolute encoder, the rest of servos uses incremental, no problem but dealing with absolute encoders is new for me, the old controller was feedback from the...

Yes the drives master and slave was connected step and dir in parallel both from the same controllers output, buy only the master was feeding back to controller, but yes i will wire both to close loop on master and slave.

That looks right to me. Except InputMode=NO_INPUT_MODE. How can you have a DAC Servo with no feedback? This is a copy from my workbench pc, i have no motors connected and set NO_INPUT_MODE to be able to watch the readouts but the machine's pc is ENCODER_INPUT_MODE. I have discovered that the origin...

Hi Tom I am dealing with a master/slave configuration, i have two servo motors on my gantry, the ch1 is the master and the ch3 would be the salved, but it does not move when jog Y axis, is a slaved motor an other axis? or it works both on one single axis? this is the motor configuration. regards // ...

Thank you Moray

I think for now i will go with wiring direct to Knonnect cards, i running out of time and customer is waiting for the machine, maybe for a future projects i would try modbus in some way.

Hi Tom regarding to modbus communication, can i use one the example c.programs to configure my slaves? this is going to be a challenge for me, but i have to try, if i don't want to run hundreds of wires on my machine. to this point I know kanalog support RS232 output, and I need to get a converter t...

Thank you Moray I've used Modbus in the past with a Kanalog, over RS232, to talk to a Click PLC. You'll need a RS232-RS485 converter, then it's a just a case of figuring out what registers you need to address via modbus, and copying those registers to/from suitable variables in in the KFlop. yes I h...

Hi Tom. I am dealing with a large cnc machine, where lots of valves and sensors are located in 3 spots of the machine basically, it actually uses sercos communication with optic fiber cable, but that is going to be replaced with modbus RS845 remote modules, i have read that kanalog supports RS232, s...

Hi Tom

How can i enable the A or B axis to tangential, i have a spindle with rotary aggregate for use with saw blades, and 90º cutter bits.

regards

Hi Tom Is there a function to watch the value of the axes read outs, for example when performing tool change, if the X axis moves 70 inches near magazine, do the next step and continue, but if for any reason the axes doesn't get to 70 inches the tool change operation must stop, is any function to ad...
