DMC-40x0 Command Reference YB • 261
YB
FUNCTION: Step Motor Resolution
DESCRIPTION:
The YB command specifies the resolution of the step motor, in full steps per full revolution, for
Stepper Position Maintenance mode.
ARGUMENTS: YB m,m,m,m,m,m,m,m or YBn = m where
n is A,B,C,D,E,F,G or H or any combination to specify the axis or axes.
m is 0 to 9999 which represents the motor resolution in full steps per revolution.
USAGE: DEFAULTS:
While Moving No Default Value 200
In a Program Yes Default Format 1.4
Command Line Yes
OPERAND USAGE:
_YBn contains the stepmotor resolution for the specified axis.
RELATED COMMANDS:
QS Error Magnitude
YS Stepper Position Maintenance Mode Enable, Status
YA Step Drive Resolution
YC Encoder Resolution
YR Error Correction
EXAMPLES:
1. Set the step motor resolution of the A axis for a 1.8° step motor:
YBA=200
2. Query the A axis value:
YBA=?
:200 Response shows A axis step motor resolution
Notes:
1. This value must be the same as the step motor resolution for that axis. The error magnitude
(QS) will climb quickly causing a false error state if the assigned value differs from actual.
