I need help please
I need someone to fix and finish my wiring diagram
and put his little resistance or engage with drivers
+ + + All equipment buy Zapp Automation
thank you very much
Why do you need to add resisters to your circuit? Give us some more detail on what you need to achieve.
Gary if your looking do you understand?If the nagging gets really bad......Get a bigger shed:naughty:
The resistors are to limit the current to the driver if voltages above 5volts are used. If 24 volt is used on the step/direction pins then a 2k resistor is required 12volts a 1k resistor is used. The bottom line is the current to the control side of the driver must be between 6-16mA
I understand now Andy and hopefully that will help Ali too?If the nagging gets really bad......Get a bigger shed:naughty:
thank you very much "audioandy" for your answer
I understand he did not need the strength that I use in my electronic installation
and I want to please tell me your opinion on my setup diagram
thank you very much
If the 10A is a fuse/breaker then it is too big, your drivers are only good for 8 amp. Calculate the current for your motor based on how you are going to wire them (parallel/series) if you are wiring them parallel then go on 2/3 of the total motor current.
For your step/direction wiring use a twisted pair preferably shielded, so on the 2M880N take one twisted pair to the PLS+ PLS- then the other twisted pair to the DIR+ DIR- the PLS+ then goes to the step pin on the PCPPS V3 the DIR+ to the Direction pin on the PCPPS V3 then join both NEG wires and join then to a GRD on the PCPPS V3.
If you are using the charge pump I would not bother with the enable signal (FREE+ FREE-) just implement a PROPER e stop circuit that will kill all movement and disable the primary side of the power supplies. DO NOT rely on MACH or any other control software for your E-Stop circuit you are using very powerful motors they will not stop if you get in the way!!!.
Have a read of this on the Gecko website this might help when working out motor currents etc.
thank you very much "audioandy" for your quick response
I understand I need to change the fuse 8amp
and I change an electrical cable thicker here I made another small body please help me to complete it and switch (SW1-SW10 ....... SW) my installation and parallel

2 - PS 750 power supplies
1 - PCPPS2
thank you very much for your help ...
I can not join the plan

Have a look at this by H.O (post 6) it may explain the e-stop circuit a bit better. The e-stop should kill ALL movement inc spindle.
I think you need to take a little longer with your build and do a bit more reading so you understand what you are trying to achive.
