Looking for support contact. AC500/ACSM1 EtherCAT

I am doing a 5-axis system, and have a number of questions. Went through official US channel for support, but I am impatient. Is there a direct contact of someone(in Germany I am assuming) that is familiar with the above system? Using centralized control.

Hi,

I have used AC500 /ACSM1 with Profibus and Modbus for 3-Axis. I had written my own interpolation logic, but i advise you to use PS552-MC-E motion control library. The package comes with samples that will get you going. You can find it on abb.com

Keep me updated.

Regards,

IP Singh

Hello bbeal and Isherpal,

can you share a technical details of your applications? Modes of operation, synchronization of axes, performance you have reach etc. Any details are interesting. I will probably do similar application and would like to know your advising of what one should care about, are there shades and so on.

Thanks.

The master is closing the position loop since 3 of the axes are rollover axes. Master roll and 2 slaves. Slave one follows master in position mode, with ability to shift the phasing. Slave 2 can follow in position mode or in velocity mode. Other 2-axes are just simple positioners. All drives are ACSM1 drives. Three are closed-loop induction motors, other two are servo. EtherCAT comms loss detection is still not fixed, so I am not doing anymore ABB EtherCAT projects until that is fixed.

Hello bbeal! Thanks for reply.
What is CPU model for this application? What is performance of motion task and EtherCAT update cycle? Closed loop inductions motors - master and other 2-axes simple positioners? Why ACSM1, did you compare it with other drives like Microflex? Why did you choose EtherCAT? Why did you choose PLC for motion and not motion controller like NextMove or other? I never heard - What are the problems with EtherCAT?
Thanks!

It is a PM591 CPU. I think it has a 4ms update cycle. Performance is good, and has been running for a year. This is a 480V application, so the M1 was best choice. Did cost comparison with NextMove, and was about the same. I prefer CoDeSys over Mint. I can unplug the EtherCAT cable from the CM579 and the PLC has no idea that it is no longer talking to the drives. No errors, no timeouts.

Did you tried with lower models of CPU - PM573, PM583? Who executes axes computation, profiling? You just send commands and setpoints to ACSM1 from PLC and ACSM1's executes positioning by itself? What ABB says about this problem with EtherCAT? Why you didn't use Profibus-DP or Profinet instead? Did you use some example or template project for AC500? Thanks!

All profiling is done in the PLC. Drives are just EtherCAT slaves running in cyclic velocity mode. EtherCAT is best motion network(in my opinion). ABB now says fix will be in next release(next month). I think I had an example to start with, but my application was pretty different from the example.

May you point me on this example application?

My system used 3 Axis (ACSM1-2.5A + Servo Motors) with profibus. CPU was PM572. The M1 Drives used Speed Mode for Axis Inching/Jog, Position mode for Program run and Homing for Hardware sync. The program came from HMI CP430 through modbus. The program had Position and feed rates for the axes. On power up homing was required. Start with single axis first rest can be added later. The M1 uses CW and SW 32bit PPO4, 1.5MBit, The interpolation of axis is done in the PLC Logic itself.

TIP: you can use addresses other than CW and SW, Also in M1 you can create new parameters/groups with Drive SPC software.
