Summary	Sets the movement mode used when the manual knob is turned.

Use this command to set the desired manual movement mode.

0 - Velocity Mode (Default)

Each detent of a knob turn moves the device at an increasing speed. There are 16 speeds in each direction. The velocity profile and the maximum speed can be set via Set Knob Velocity Profile (Cmd 112) and Set Knob Velocity Scale (Cmd 111).

1 - Displacement Mode

Each detent of a knob turn moves the device for a fixed number of microsteps. The device stops if the number of microsteps left in the maximum range is less than the requested move command number. The number of microsteps per knob detent can be set via Set Knob Jog Size (Cmd 110).

NOTE: User can also quickly toggle between the two modes by depressing and holding the knob for 1 second.

This setting is stored in non-volatile memory and will persist after power-down or reset.
