Fast Update Rate Mode

The DMC-2x00 can operate with much faster servo update rates. This mode is known as 'fast mode' and allows the controller to operate with the following update rates:

DMC-2x10, DMC-2x20	125 usec
DMC-2x30, DMC-2x40	250 usec
DMC-2x50, DMC-2x60	375 usec
DMC-2x70, DMC-2x80	500 usec

In order to run the DMC-2x00 motion controller in fast mode, the fast firmware must be uploaded. This can be done through the Galil terminal software such as DMCTERM and WSDK. The fast firmware is included with the original DMC-2x00 utilities. To set the update rate use command TM.

When the controller is operating with the fast firmware, the following functions are disabled: Gearing mode

Ecam mode Pole (PL)

Analog Feedback (AF)

Stepper Motor Operation (MT 2,-2,2.5,-2.5) Trippoints in thread 2-8

DMA channel

Tell Velocity Interrogation Command (TV)
