Hi, with D425 / D435 / D445 you have a scalable performance. This means: the limitation of the quantity of axes depends on your required performance. Performance means: motion control performance (how many axes in which servo and interpolator cycle) and how many PLC code for your programm. Siemens has a nice tool called SIZER ---- there you can get an idea about your performance (dependent on Hardware D4x5, servo and IPO cycle, quantity of axes and functionality like pos, gear or cam axes). --> see attachment (SIZER is really cheap, it's only a small handling fee) To give you an idea: D425 with 2 synchr. axes + 4 pos axes: - Servo = 3 ms, IPO = 6 ms (or 4 / 4); 2 / 4 would be critical D435 with 2 synchr. axes + 4 pos axes: - Servo = 2 ms, IPO = 2 ms; 1 / 3 would be critical. Of course, these are estimated values! You also have 2 IPOs - that means you can share between axes with high and low performance. I hope, it will help you a little bit.
