With performance you mean.... ? (loss of energy?) ..

Hey Sina :), I'm Back. I have been making some calculating in regards to controlling my DC-servomotor with the Geo Brick LV. I have a very small motor: Inductance (phase-phase)=35uH and Resistance (phase-phase)=2.3Ohm According with what on page 156 of the Geo Brick LV User Manual, that gives a time constant of T=15.2uSec and a PWM freq. of 209.175 kHz. I don't think Geo Brick LV can go that fast. So, I was thinking of using a inductance in series with the motor. The inductance is: 2.7 mH and 8.9 Ohm. With this, the combine inductance is 2.735 mH and the resistance is 11.2 Ohm. So T=244uSec and PWM Freq. is 13.034 kHz. With this we can use a 20kHz PWM Freq. and solved. Will this work? What other problems could I encounter with such small motor? thanks, Juan Xavier Reyes

Hello, Does Turbo Clipper Drive support BISS-C? I know Turbo Pmac2 does. But, where is the port to connect a encoder with BISS-C? Thanks

I think I found the solution. I would not use the hall sensors on my motor, instead use the absolute encoder and the procedure "Absolute Power-On Phasing: EnDat | SSI | BiSS" on page 186 of the "Geo Brick LV User Manual" to move accurately. Right?

Sina, I'm thinking about using the integrated Controller/Amplifier of Geo Brick LV. (Power Brick LV is coming soon, but not yet available on the web page). Just one question: I have a 3 fase DC-Servomotor with integrated Hall sensor. This motor moves a axis that is monitored by a BISS-C absolute encoder. Can I forget about the Hall Sensor, and still accurately move the axis? I mean just not plug in the Hall Sensor. Pardon my ignorance. Thanks, Juan Xavier Reyes

Sina, Thanks for the answer. What about combining Renishaw BISS/C abs. encoders with DC Servo motores. Is it posible to control 6 axis in a close loop with this two? Thanks!

This is a list of the components I have: 1.-Turbo PMAC2 CPU 2.-ACC24E2A 3.-ACC24E2A 4.-ACC24E2A 5.-ACC51E 6.-ACC84E 7.-ACC84E 8.-ACC84E 9.-ACC84E 10.-ACC28E but I'm only using two cards ACC84E to read encoders BISS and two cards ACC24E2S to move stepper motors. All the wires can be redone. I'm only asking if the actual code can work on both platforms without having to make any syntax changes.

hello, I have a code that works fine in a rack with, Turbo Pmac2, ACC-84E for BISS reading, and ACC24E2S to control stepper motors. Since I'm only using 6 axis, I was thinking about buying a Geo Brick with 8 axis instead of buying the 32-axis TurboPmac 2. Do you think there is going to be any problem with running the code I have for my last aplication? Thanks

Hello, I used to control one Turbo Pmac with Pewin32 Pro. Now I'm trying to develop a interface for the control of two Turbo Pmacs at the same time. Where can I download the PComm32Pro driver for the communication with Turbo Pmac? Also, will there be any problem if I try to open 2 windows of Pewin32Pro with one license? Just curious. Thanks!!

Could I use a PLC to compute the same variables as the Motion Program and then instead of calling the motion program I will only enable the PLC, which it self disables it self?

Then, it can't be done? Calling a Motion Program from the Forward Buffer.

I'm trying to call a Prog from the Forward buffer. I'm using a Turbo Pmac2. The error while trying to compile is: PMAC Error 5, Command not allowed unless buffer is open. Line 238, "CALL 12;238" Any Ideas on how to define a buffer and be able to call the program 12?

I have two motors setup the same way, but the reading of the encoders differ by a factor of 32 when they are in the same position. I'm using a Absolute position Renisaw Biss C encoder. The resolution is 0.05 um, so I use a Ixx08=20. For motor 1 I get the following readings: (This is correct) The encoder sends 500000 in 26 bits. I process this data with the conversion table using Parallel Y word data, No filtering, and Normal Shifted, and so I get: (I8000=$278c00 I8001=$01800) X:$3501 is 500000 X:$3502 is 0 I join this two in the recommended variable for actual position: M162=(X:$3501 + X:$3502)*I108 (Not the actual code line) =500000*20=10000000 And the Position Window in Pewin 32 reads 500000 cts. This is correct. However, motor 3 is configured the same way, and makes all the calculations in the right way. But, the position Window in Pewin 32 reads 15625 cts. Is wrong by a factor of 32. Im using a total of 4 motors, and only motor 3 makes this extra calculation. Were does the Position Window of Pewin 32 takes the values from? Which variable. Any ideas on what can be wrong? THANKS

I'm using a ACC - 24E2S card in the 4th slot. It is the 4th Servo IC. The thing is that the 4th Servo IC is configured the same way the 3rd Servo IC is. They are both 24E2S and both are used for the same thing, controlling a driver that makes the commutation. However, the 4th Servo IC enables the driver without sending any pulse or direction to the driver, and so, the motor does not move. The 3rd Servo IC works just fine. For the second channel of the 4th Servo IC Im using the attached configuration, and the motor 6 is configure as the attached file shows. I have no idea what can be wrong, since the 3rd card works with the same setup (changing some addresses). Please Help. Setup_motor_6.txt Setup_Servo_IC_4.txt
