Note
These Servo IC 1 clock settings are optimized for a good quality
analog output signal. If any one of axes 5-8 is used for direct PWM
control then the analog output signal quality should be compromised
with a much lower PWM frequency, or not used at all.

Analog Outputs Suggested M-Variables:
// De-activate Motors 5-8 to write directly to the analog outputs
I500,4,100=0
I500,4,100=0
; De-activate channels 5-8 to use direct write
I569,4,100=816
; Set Output Limit --User Input
// Analog Outputs:
M502->Y:$078102,8,16,S
; Analog DAC Output (DAC5), Connector X9
M602->Y:$07810A,8,16,S
; Analog DAC Output (DAC6), Connector X10
M702->Y:$078112,8,16,S
; Analog DAC Output (DAC7), Connector X11
M802->Y:$07811A,8,16,S
; Analog DAC Output (DAC8), Connector X12
Testing the Analog Outputs
With the setting of I7100=735 (per the above example), writing directly to the assigned M-variable (i.e.
Mxx02) should produce the following voltage output:

The output voltage is measured between AGND and DAC+ for single-ended operation and between
DAC- and DAC+ for differential operation.
Note
Writing values greater than I7100 (i.e. 735) in Mx02 will saturate the
output to 10, or 20 volts in single-ended or differential mode
respectively.

MACRO connectivity provides more analog output options, e.g. ACC-
