DMC-40x0 Command Reference BO • 51
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
0.0003.
n = ? Return the brushless offset for the specified axis.
USAGE: DEFAULTS:
While Moving No Default Value 0
In a Program Yes Default Format 0
Command Line Yes
Controller Usage
ALL CONTROLLERS
OPERAND USAGE:
_BOn contains the offset voltage on the DAC for the specified axis.
RELATED COMMANDS:
BA Brushless Axis
BB Brushless Phase Begins
BC Brushless Commutation
BD Brushless Degrees
BI Brushless Inputs
BM Brushless Modulo
BS Brushless Setup
BZ Brushless Zero
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.
HINT: To assure that the output voltage equals the BO parameters, set the PID and OF parameters to
zero.
