I have a projet PPmac including C applications (background CApp) When IDE is connected to the PPmac, I can build and download all without any problem. If now, IDE is not connected to any PPmac (in order to prepare upgrade or ohters), when i just try a simple build or re-build the project in order to recompile my C code, i got the followings errors : E:\x\e\2022 02 24 - RT5 - copie (IDE 4.5.2.9\RT5.ppproj(370,5): error : 0 [main] make 16140 child_info_fork::abort: C:\DeltaTau\PowerPMAC\Compilers\bin\cygiconv-2.dll: Loaded to different address: parent(0xA00000) != child(0x820000) E:\x\e\2022 02 24 - RT5 - copie (IDE 4.5.2.9\RT5.ppproj(370,5): error : make: vfork: Resource temporarily unavailable Is there a way to don't have these errors ? Thank's in advance.

Hello, With a system with PowerPmac Etherlite (only one Gate3) + 3x GeoMacroDrive. - Firmware 2.5.0.4, IDE 3.1.4.0 We want Macro-ring and Phase-clock at 16 kHz, Servo-clock 4KHz. We done : Gate3[0].PhaseFreq = 16000; Gate3[0].PhaseClockDiv = 0; Gate3[0].ServoClockDiv = 3; Gate3[0].PhaseServoDir = 0; Gate3[0].MacroModeA = $403000; Gate3[0].MacroModeB = $009000; Gate3[0].MacroEnableA = $0FC57500; Gate3[0].MacroEnableB = $1F800000; As soon as downloaded + save + $$$ we got in the task manager : Phase Freq.: 20 KHz !!! Strange isn't it Servo Freq.: 5 KHz Solution found : Gate3[0].MacroModeB = $001000; and then all is ok: Phase Freq.: 16 KHz, Servo Freq.: 4 KHz Could you explane me why .MacroModeB =$009000 do that problem on the clocks frequency ? Thank you in advance.

Thank you for your answer. It works perfectly. Note : We have found also some additional information in the Acc-84E documentation

In the Geobrick-LV user manual it is only spoke about Yaskawa Sigma III 20-bit Absolute Encoder. Is it possible to have a Yaskawa 24 bits (or more bits) encoder. The reference of my encoder is RA24YUA052B15V. Thank you in advance.

Hello, With a Stepper in micro-stepping (without any encoder) on a GeoBrick-LV, can i use the backlash functions ixx85 ixx86 ixx87 ? Thank You

Hi Many thanks I will do. KR.

Dear All I'm trying to power up the ModBus TCP/IP communication between Geobrick (Client) and RS232 to Modbus TCP/IP translator (Server). But there is no way to have the communication OK because the server can't answer ModBus request with ID 0 that send the Geobrick. Is there a way to change the ID number in the ModBus commande i67 + offset registers from 0 to 1 for example? For memories the ModBus request are looking like: ID + FC + Addr register + Length registers. Today the Geobrick send 00 04 0014 0014 and the server would like to receive 01 04 0014 0014 ( ID 1, ModBus fonction 4, Start register address 20, and 20 registers read. I was not able to find the answer in the "Modbus Definition and Design" documentation. Many thanks for your help. KR

We have customers who need retrofit of their old machines with Pmac (ISA, VME) We have several hardware solutions (BrickControler, PowerBrickControler, ...) The problem is regarding the software. They have several PLCC in memory and not the source files, only a .cfg backup. Have you information about how the PLCC are compiled ? Or about how can we decompile or understand the code included in the area "compiled PLCC's" of the .cfg file ? Best regards.

Hi, Is it possible to use a LVDT sensor with a Gate3 + Resolver feedback option ? I mean, does the PPmac can use directly the wires +/-Ref, +/-Sin, +/-cos of a LVDT (of course without adding a LVDT signal conditionner) as it is possible for a Resolver. If yes, what configuration i have to do ?

On a Acc-28E, there is on each chanel the outputs ref. +/-5 volt. What is the max current available on those outputs ? PS: We need 25 milli Amps.

We have two BrickController-LV linked over MACRO. One in MACRO Ring master, the other in Slave state. All is working (in Torque-mode) ok. On the Slave, in IDE, the view MACRO-Status has the bit "AuxSlaveConfigFault" set. What means this bit ? (nothing in documentations). What could be the cause of this information ? Thanks in advance.

In the "Geo Brick LV Setup Assistant 2.9" the configuration for the following motor : Brushless, Peak 4Arms, Rate 2.5Arms, Bus 48volt, Motor max 48v, time 1sec, (GeoBrick-LV 5A, pwm 4.517KHz, phase 9.034KHz, servo, 2.259KHz) Give: I157=2963, I158=118, I169=4742 With the formulas in the GeoBrick documentation, and in DTcalcs2008.exe, (and in my own calculator), i get the values : I157=2964, I158=29, I169=4742 I think there is a problem about the ixx58 calculated in the excel file. PS: I have not found the correct thread in bugzilla to put this topic.

Thank you Steve, I'll test it in some weeks at the customer plant.

Thank you Steve, that's wonderful. Could you tell me the best way to get a position from AdcEnc[2] & [3] ? I suppose it's with EncTable[n].type =4, but could you give me the full configuration ? Thanks

Is it possible to connect on Acc24E3 or Pbrick with sincos option, à second sincos on the pins named "altsin", "altcos" (u,v,w,t pin) ? On some encoders there is 2 sincos signals, one with several period/rt, the second with one périod/rt. I would like to phase the motor with the second sincos connected on altsincos pins. Is it possible ? How do that ? Thanks.
