Fast Update Rate Mode

The DMC-14x5/6 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:
1-2 axis
In order to run the motion controller in fast mode, the fast firmware must be uploaded. This can be
done through the Galil terminal software such as Galil SmartTerminal and WSDK. The fast firmware
can be downloaded from the Galil website. 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
