General Mach Discussion / AD Sureservo and Mach 3 modbus
« on: April 09, 2009, 03:38:30 PM »
Has anyone had any success using Mach 3  modbus functionality to communicate with Automation Directs sureservo amps?

My initial research has gained me this understanding:

1. PC is the master(need RS232 to RS485 converter)
2. Then each sureservo drive will act as a slave.
3. I think i need a junction box to connect the drives to my serial port.
4. Enable modbus in mach 3
5. setup port and pin addresses for each drive

Questions:

1. Is any part of my understanding listed above flawed?
2. Are there any potential timing problems associated with serial communication to several servo drives?

Thank You
