CSMIO/IP-S with Inovance SV660P Drives
Hello!
I wanted to test some drives from Inovance in an machine from a customer with a IP-S.
The general wiring is done. In Step/Dir configuration of the drives there is an option for "High-speed differential".
The specifications for that mode are:
Maximum Frequency (pps) 4Mhz (fits for the IP-S)
Minimum PulseWidth (us) 0.125
Is the minimum PulseWidth in the IP-S range?
kind regards

Hello.
First of all, it is not the case that if the drive supports 4Mhz, the motion controller should be configured to generate 4MHz.
In practice, even in very fast and precise machines, it never comes close to 4MHz.
I will add that only a few drives withstand 4MHz, usually less than 3MHz.
Let me add that the CSMIO/IP-S controller, in the case of simCNC software, can generate a step/dir signal with a frequency of 8.5MHz.
Returning to your question, the minimum pulse width depends on the frequency and filling of the drive's supplied step signal.
Assuming that you want to provide the drive with a step signal at a frequency of 4MHz and that the filling of this signal in the case of CSMIO/IP controllers is always 50%, you get a simple calculation:
1 : 4MHz : 2 = 0,125us
So the minimum pulse width for 4MHz is 0.125us.
Best regards,

Hello!
Ah thanks for the explanation, now i understand the combination of drives / controller regarding the pulse width.
I guess then everything will work fine.
