You can edit the ini file directly to set the accelleration.
Read the docs on ini file configuration
But I think you will find more than 3000-5000 will shake your machine apart,
 

This was a general question about the settings for very common servos, not specifically about maximum acceleration. That was simply to point out that I can't even enter a calculated value.

I am looking for examples of known good settings for a Clearpath SDSK servo, for all of the entries in pncconf.

I will double check for shorts on P1 and the shield terminate at 7i96s.

I will update

Hi rodw. Thanks for the pointer. You must be referring to this thread below. I can't believe I missed it.

I'm going to try that patch and report back.

Ok , thanks.

All HAL float pins are 64-bit doubles.

Are you needing to deal with Single precision floats from something like Modbus or EtherCAT.

In the general case there is no way to do this, as there is no way to know what was intended. But if there is an assumption that the value is approximately continuous then you can make an inference.

That said, it's hard to think of any engineering quantity inside a CNC controller that could overflow. (encoder and stepgen integer counts potentially can)

Also, I don't think that your initial assertion is correct:

Its possible but requires the Efinity JTAG software and a compatible JTAG interface
Probably best that the card be returned for analysis/repair/replacement.

 

In general for an analog+ encoder system I would suggest a 7I97T or 7I92TM+7I77

Are the drives working?

The card is new one. The power supply is 5.12 V.
I didn't use mesaflash, the standard flash is ok for me.
If the flash is corrupted, Is there a way to try to reprogram the card?

you may need one or both of these in your hal file:
For more info see
linuxcnc.org/docs/html/remap/remap.html#...lated_codes_t_m6_m61

P1 is the digital (and low voltage side)

Is the shield terminated ONLY at the 7I96S end?

Thank you for your reply.

The cable is shielded and twisted pair.

Sorry, what you mean by digital side of THCAD (IN+ IN-) ?

What kind of lathe and which kind of tool changer mechanism

Sounds like either a power supply issue (marginal 5V)
or corrupted flash (wrong bitfile written, which is possible
with older mesaflash versions)

I guess it could be a failed flash chip, but this is pretty rare.
 

With your existing hardware, lowering the base thread value
is the only thing you can do. How low you can lower it depends
on the kernel (turbo mode etc) and isolcpu settings.

Did you run a latency test? (why did you choose such a long base thread period?)

Hi,
I have a 7i96s that worked fine for a day and then during a reboot it was no longer recognized by linuxcnc. Looking at the LEDs on the card I noticed that  the init, done and power LEDs remain on and I don't have the ethernet link up.
Following the manual I put the w1 and w2 jumpers in the up position, but the board remains with the LEDs on and ethernet link is down!
What can I check?
