Command by Distance & Time?

Postby alands » Tue Jun 06, 2017 10:52 pm

I'm using direct data operation commands, via RS-485 modbus, to control an AZD controller. Is there a control method available where on specifies and distance, and the time to complete the move?

We have an application where the slide moves very slowly, and are running into the limits of the system, even when using the electronic gear ratio. In some cases the user calls for a move that translates to 7.3 Hz, which rounds down to 7, but that's not an adequate solution. We're hoping to find a mode where the controller automatically interleaves the move, alternating between 7Hz and 8Hz as appropriate.

Thanks for the help

Hi alands,

In regards to your application, the AZD controller does not have a function which can alternate between 7 and 8 Hz. Therefore, the alternation between 7 Hz and 8 Hz would need to be a function of your control method which is communicating through RS-485 Modbus.
