Inverts the DAC
On NextMove, if bits 0 through 3 are not set then
DACMODE assumes 12 bit emulation, allowing a binary
range of ±2047.

DAC invert
The
DACMODE effects all modes using the DAC channel, servo demand output, TORQUE output and
direct control with the
DAC keyword.
The other modes gives a greater resolution and therefore allows for finer motor control.
Changing DACMODE will require affected servo axes to be re-tuned.
Example:
DACMODE[0, 1, 2] = 1; : REM 14 bit mode on channels 0, 1 and 2
DACMODE[3] = 0 : REM 12 bit emulation on channel 3

Description:
Certain system parameters, such as axis velocity, can be monitored externally by outputting the value
through a DAC channel. This can be useful for tuning and debugging purposes. The
DACMONITORAXIS keyword specifies which axis is to be used for monitoring through the DAC channel.
