I used ACC-24E2S in project, in open loop control mode, when umac work for a period of time and the temperature of UMAC rising highly, it will caused the one of axis lost control and moving. it is dangerous.. is there any solution to solve ? and i also used ACC-24E2A before, it also occured error because of temperature. the following error occured and stop immediately as close-loop control. frankly speaking, it is disappointed for its heat dissipation although its function and other performance is nice.

Any thoughts on the best way to control two axis moving in a vector? Right now we are bringing our gap voltage into and analog channel and using timebase following. The problem with this is the process is erratic. We use reverse look ahead to change directions if we drop below our set point.

I want to download an existing program on my PMAC Turbo. What are the steps to getting the program that has already been flashed to the PMAC Turbo using PEWIN32? Thanks

In my app motors #3 and #4 belong to the same vertical axis Z (#3->100z, #4->100z). I use Master/Slave config (position following mode) to control the axis. Motor 3 is a Master, Motor 4 is a Slave. In feedrate (linear) moves motors have almost equal speeds but different actual positions at the end of move. Position difference depends on feedrate setpoint. For example, if both motors go from z0 to z500 at speed F900, at the end of move actual position of Master is 500, Slave - 500.35 mm. The same move by F9000 gives actual position of Master 500, Slave - 503.5 mm! How to get positions of both motors the same? In feedrate (linear) moves (G01, G02/G03)…

If I am not commutating can the UVW inputs (J7 MMACH3)be used for general purpose input? I'm using a Turbo Clipper. Thanks Chris

Where can I find the address of the data from the result of the MOVETIME command? I would like to define an M-variable and query it to display in an application.

We have 2 PMAC commutated Linear motor with high resolution encoders. The current resolution is 5nm and Motor Scale is 200,000. We have difficulty in increasing the resolution to 2nm as the encoder can be set to 1.22nm. The linear scale is a 20 um grating and the resolution mentioned is a interpolated one. Since we need to perform the commutation on PMAC, the counts exceeds 32M. How can we perform the improvement? Will Encoder Conversion Table help? Thanks in advance. Regards, Raghav

When we have been asked by our customers to upgrade a legacy NC system from Windows whatever (NT4, 2000, or XP) with a Turbo PMAC2 ISA, historically we have required them to purchase a new Turbo PMAC2 PCI as the PCommServer device drivers were not comparable for ISA units. With the termination of this upgrade path for our customers employing these units (approximately 150 machines at $450K each), is there a way to make PCommServer work for ISA Turbo PMAC2 boards under 32 bit Windows 7?

I guess the end of life notice somehow slipped by us. I understand the AD1868 DAC chips are discontinued, but does Delta Tau plan a replacement board? We have roughly 1200 of these in the field, and have somewhere around 1-2% per year failure rate on them.

Hello all, I am considering replacing my old and problematic Millplus controller to a new one, Delta Tau seems to offer everything which is necessary. The machine is a DMU 60 P from 1999 with Simodrive 611 drives et 1FT6 motors plus Heidenhain rules. These are operating well and I would like to keep them, in this case which hardware should I chose from Delta Tau to replace the millplus? Cordially Francois

I work extensively with the Turbo PMAC Brick. On the face of the device, there are 2 groupings of LEDs. The upper right corner contains 3 green LEDS that should be on if the 5VDC and 12VDC power is correct. Near the AMP3 connector, below the Ethernet/USB connectors, there are 4 LEDS. The top LED is Red and always on in my experience. The next LED down I've never seen illuminated. The 3rd LED is red, Label as WD (watchdog). Obviously, we don't want to see that one ON. The last LED is Green, always on in my experience. I have pored over the Brick Hardware Ref. Manual and can find no clear description of the LEDS, what colors they may show, and specifically, …

Is it possible to commutate a brushless servo using only the Hall sensors on a GeoBrick LV? Or is it essential to have an encoder to measure the motor position?

Dear All, I had come back with my very OLD problem again. Previously we didn't not have a DPRAM IC in our Turbo UMAC system. Recently we have upgraded to DPRAM option. I still have the same issue as before - RUNNING a large NC program from a file and also updating the HMI/GUI. Currently, since we have the DPRAM option, I intend to use the BIN ROT BUFFER option and send the ASCII code by PmacDPRAsciiStrToRot() or PmacDPRAsciiFileToRot() function. I need to also update the machine motor status and run PLC in the background to update the HMI/GUI and safety aspects. 1) If I download a set of codes using the I16 & I17 buffer limits, can I reterive the status using …

hi: If I use the HMZ to clear the latch position and the actual position is very different, what should I do to make the latch position correct? for example: m162 = 125000 m103 = 22250 How to correct the conversion?

I'm relatively new to LabVIEW and PMACPanelPro2 so pardon my ignorance. I move a motor with the "Jog To" button in the Motor Jog Control Cluster. The mechanical action of the button is set to Latch when Pressed. I need to synchronize the motor movement with a data logging operation. I use a 'Save' button to start logging, which is set to Switch when Pressed. I want to start the motor movement 2 seconds after the logging starts. The flow I want is Run VI -> click Save -> wait for 2 seconds -> programmatically click "Jog To" -> Stop VI after motion is complete. How do I go about programming the click action for the "Jog To" button? Uploaded the code 'Fo…

Hello everyone , I sort of have a long story but our company bought a CNC design from a smaller company which uses turbo PMAC and long term were supposed to be tech support for this new control . As of now I know nothing of the PMAC systems , does anyone have any advice on how to start learning Turbo Pmac , Has anyone taken the training from Delta Tau's facility in California and it is friendly to completely new users ? I know servo PID concept and general programming knowledge so hopefully its not too much over my head.

I'm hoping for an explanation of how look ahead works in a Turbo PMAC2 (Brick Controller). We're controlling a rotator in either a 'Track' or 'Slew' mode with the code listed below. Segmentation is disabled and blending is on, so my impression is that Acceleration and Velocity I-variables would dictate the response regardless of the Ts value specified. For a Slew move, P250 is updated once with the destination and we have found that the rotator will accelerate at the I217 rate to the max speed of i216, but then essentially abort and decelerate at I215 once it gets to the final position. Why? If this is a look ahead interference, what is it looking ahead to when o…

Hi All I am seeing a *Phasing error* every time I reset the PMAC. It goes away when I phase each motor. However this is the first time I am experiencing such a behavior and would like to know; 1. What could be the cause? 2. How to resolve this behavior? Thanks Chanaka De Silva NSLSII BNL
