Hi Steve, Apologies for the late reply. The S/N of the card is P927270 and Firmware is 2.3.2.5 Thank you.

Hi David, Thank you for the advice. FRAX(C,X,Z) works fine. Now I'm facing issue with the C feedrate. I would like to provide a Ffeedrate F72000 corresponding to 200 RPM, but the C feedrate is struck at 54000... Seems the problem is due to some settings with Segmove or lookahead. Any advice on the same?

Nope it's the same error.. Shortened version " cp: cannot create directory `/opt/ppmac/usrflash/Project/System': Read-only file system .... (more lines of the similar affect) cp: cannot create regular file `/opt/ppmac/usrflash/Database/pp_prog.sym': Read-only file system cp: cannot create regular file `/opt/ppmac/usrflash/Database/pp_subprog.sym': Read-only file system Successful: SaveConfiguration using /var/ftp/usrflash/Project/Configuration/pp_save.cfg Successful: SaveCustomConfiguration using template /var/ftp/usrflash/Project/Configuration/pp_custom_save.tpl Saving To Flash: Please do NOT Power off until Finished!!!

Dear All, I'm trying to save a project after building and downloading successfully. Unfortunately, it throws a list of error stating that the files are READ-ONLY. Also the variables created are accessible until PMAC is powered off. Once powered OFF all the parameters are missing. Can I know what causes these issues? Thank you.

Dear All, I'm working on a three axes system with two vector feedrate linear axes (X&Z) and one rotary C axis. I would like to know how to set the three axes to move synchronised based on a given feedrate? Currently if running C-axis alone, provides a max feedrate of 1 motor unit/ min. Can anyone suggest the best practice to assign and synchronize axes motion? Thank you.

I would like to know the differnece between the additon and subtraction of two encoders input (space at 180 dgreee). In this case, the final Motor[].Enctype should be chosen as type 7 (as two of the actual encoders are Type 7 and we use ACI) or Type 1? Also how do I use another low resolution encoder as the feedback for Velocity control (Dual feedback). So in total I have 3 encoders for a single axis. Any procedure or manual would be helpful. Regards.

Hi Zhong, We isolated all the cables and checked for the wiring. The probelm is still persistent and not sure what these spikes mean. We have infact seperated even the power for PMAC and motor from rest of the machine. When I perform the open and closed loop test stilll the issue occurs. Starngely, the servo command produces spikes (as shown in attached picture). Any suggestion/advice will be helpful. Thank you. Regards, Raghav

Hi Zhong, Thank you for the reply. I will look into the wiring and get back to you. Regards, Raghav

Hi, We face this problem of IDE crashing each time the motor testing is performed. It works fine until the test does not succeed, but crashes soon after the tests are successful. Similar situation with tuning module as well. Is it common or any bug related to IDE wizard mode? Also setting up of encoder type to 7 ( extended hardware ACI) is not possible through the wizard mode. Kindly suggest a remedy for the above mentioned issues. Also I'm looking for a set-up manual/guide to perform motor commissioning. looking forward to hear from someone. Regards, Raghav

Hi, We are setting up a brushless motor (LM). We have not been able to set it up both through the wizard and manual setup mode. Our hardware is ACC24E3 with ACI and 465 (Dual core APM) CPU. We need some procedure/manual to guide us through as we couldn't succeed in setting up the axis. Attached are some screenshots of the error during the open loop and initial tuning. The velocity plot shows few spikes which corresponds to some positional jerk motion. We are using a 0.512 micron pitch encoder. This eventually leads to I2T fault on the PMAC amplifier end. Looking forward for some suggestions with regards to 1) Ideal Phase, Servo and Enc clock settings 2) Any methods to check the encoder signal loss (inside pmac). We had testing the encoder using the OEM provided electronics. The signal strength is above 85% across the motion range. 3)Phasing - To use the Hall sensor and make a motion-less power-ON phasing protocol. If this method is not recommended, kindly recommend a suitable/reliable method for phasing 4)Tuning guide. Kindly let me know if you need any further information. Regards, Raghav

Dear all, I had faced issues in the past with dpram on Turbo PMAC and managed to make it work with the help of Steve. I used Bin rotary to execute the larger NC codes and normal coordinates update through DeviceResponse(). I tried the similar code on a new machine with v1.95 (previously v.1.94) and the program initially was executing for smaller size programs and also updated coordinates. We tried to run larger file size and it failed. After which, we had changed the buffer size and now none of the file gets executed. We provide a "&1B0R" after sending a set of NC lines and I57=1 and I58=1. Size command gives 25006 while rot buffer closed and 13046 while it's open. Lookahead is 1000,800 and rot buffer size 3000. Can anyone advice on this issue?

Thank you Steve. I had contacted technical support for the FW update.

Hi Steve, I'm facing an issue with the Power PMAC IDE. The application crashes a couple of times while trying to add motor, see the CPU Core Mgt. and particular when I try to enter into the Tuning option. Currently no physical axes are connected to the PPMAC. I'm using a PPMAC CPU 460x (firmware 2.0.01) and IDE version 4.5.2.9. Any advice? Regards, Raghav

Thank you Mr.Richard. We understand it now. Thank you.

Dear Shadi, Sorry for the delay in replying to you. I shall contact you through email. Regards, Raghav
