How fast is the refresh rate of commands delivered by a Delta CNC controller to servo motors?Through DMCNET, commands delivered by a Delta CNC controller to servo motors refresh at a 1 kHz rate. However, if Delta servo drives such as the ASDA-A2 series are connected in the system, a more precise position control can be achieved and the refresh rate can be enhanced up to 8 kHz by the Fine Interpolation Commands.
