PowerPMAC system with ACC-28E

Hi,

In our PowerPMAC system, we have the following cards:

PowerPMAC processor card

ACC-11E

ACC-24E2A (qty.2)

Just recently we have added an ACC-28E card for analog data acquisition. The gate index is shown below for addressing:

ACC-24E[4],ACC-24E[5],ACC28E[15]

We are currently using ACC-24E[4] card for master clock of the system with 24kHz of phase freq and 12kHz of servo freq. We can power up all of the motors without any issues. However, we can't seem to get motion in any of the axis (with the jog command). We tried tunning but was not able to get any motion. Has anyone experienced similar issues?

 

Thanks,

Lei

Can you change the address switch on ACC-28E such that it is addressed as IOCard index 1, and repeat the test?

 

SW1-1   SW1-2   SW1-3   SW1-4
-----   -----   -----   -----
OFF     ON      ON       ON  

 

Also, after adding/removing hardware to/from a Power PMAC system, the CPU detects a change in the hardware and will not load your saved project/settings and loads the factory default settings only. Have you downloaded your project/settings after adding the card to the system?

Sina,

We switched the IOCard index to 1 but we are experiencing the same issue as before. With regard to adding the ACC-28E card, I would put in the card and do a '$$$***' then save and reset. Upon power up I would download the solution then the motor parameters. Please advise if there is anything else we could try.

 

Thanks,

Lei

coles55,

 

Can you please check the E5, E6 and E7 jumper settings on ACC-28E. Also can you please repeat your test with nothing connected on ACC-28E connectors. I'm concerned about the +/-15V signal on the backplane since ACC-24E2A uses the +/-15V on backplane for DAC outputs.

 

Regards,

Sina,

E5,E6 and E7 jumpers are all on pins 2 and 3 (backplane +/-15V). We have been testing the card with nothing connected on the analog inputs. Only thing connected is the backplane.

 

Thanks,

Lei
