BO
FUNCTION: Brushless Offset
DESCRIPTION:
The BO command sets a fixed offset on command signal outputs for sinusoidally commutated
motors. This may be used to offset any bias in the amplifier, or can be used for phase
initialization.
ARGUMENTS: BO n,n,n,n,n,n,n
or
BOA=n
where
n specifies the voltage n is a signed number in the range -9.998 to +9.998 with a resolution of
0.003.
n = ? Return the brushless offset for the specified axis.

OPERAND USAGE:
_BOn contains the offset voltage on the DAC for the specified axis.
EXAMPLES:
BO -2,,1
Generates the voltages -2 and 1 on the first DAC A, and the second DAC
C of a sinusoidally commutated motor.
