Connecting PCI 7350 to Applied Motion BluAC5-S drive

[Brian_Beal]

Andre-

Have you been able to get the motor to move correctly by using the drive by itself with the Applied Motion software?

Brian,

Yes, no problems there.

Are your encoder counts tracking in the proper direction in MAX?  Count up CW, count down CCW?

What mode have you selected for the Blu-AC5?

Did you run the motor timing wizard in the Blu-AC5 software?

Have you optimized the settings of the motor drive in the BLu-AC5 software?

Ryan,
I have not tracked the encoder counts in MAX since I have not been able to get the motor to move correctly.

I have selected  velocity mode in the BluAc5 drive.

I have not ran the timing wizard since I am using an Applied Motion motor and I have uploaded the approriate motor profile povided as part of the Applied Motion software.

The motor drive settings seems to be close to optimized since I can control the motor using the Applied Motion software and I get small position errors and practically no difference between the set velocity and the actual velocity.

I also have a 40:1 gearbox attached to the motor.
Thanks
Andre

"I have not tracked the encoder counts in MAX since I have not been able to get the motor to move correctly."

Brian Beal suggested this very thing in the beginning of the thread.

"Check to make sure you are reading the encoder in MAX and that it is scaled properly by turning the motor by hand and watching the counts. "

Any luck checking the encoder counts in MAX?

Ryan,
I was thinking to first make sure that the physical connections were correct before checking for things such as the encoder counts, but since both you and Brian recommend that I check the encoder counts, I will do that using the connections that I currently have.  I will be in the lab later today to check on that.
Thanks

Using the UMI is much easier to verify the correct signal connections.

I found that I had to connect the A Phase outputs from the BLu-AC5S to the B inputs on the UMI, and the B phase outputs from the BLu-AC5S to the A inputs on the UMI to get the encoder to count properly (count up in CW direction, count down in CCW direction.)  The pinout from the BLU-AC5S manual is what I used, off the DB25 - just like you are. 

Looking over your connections list - it seems like you are not connecting the Analog Out - from the 7350 to the Analog In - on the BLuAC5S

The encoder outputs from the BLu-AC5S are also line driven outputs, so using the UMI-7764 you can connect up the A and Anot and B and Bnot from the BLu-AC5S DB25 Out1.

Because they are line driven outputs you may not need to use the 5V power supply normally required to be used with the UMI-7764.

Ryan,

Thanks for the info.  I am going to use the UMI as you suggest.  I do not understand why you say that it does not look as if I am connecting the Analog out from the 7350 to the Analog in on the BluAC5S.  I had pin 29 (Analog out) on the 7350 connected to pin 1 (Analog in+) on the BluAc5S, and pin 31 (Analog out gnd) on the 7350 to Pin 19 (Gnd) on the BluAC5S.  Am I missing something?

Thanks

Andre

That is the incorrect way to connect the Analog signal to the BLu-AC5S.

The In/Out1 Terminal uses Pins 1 and 2 for the analog control signal connections.
