EXAMPLES:
1. Set the step drive resolution for the SDM-20640 Microstepping Drive:
:YA 64,64,64,64
2. Query the D axis value:
:MG_YAD
:64.0000
Response shows D axis step drive resolution
Notes:
1.
This value must be the same as the step drive resolution for the axis. The error magnitude
(QS) will climb quickly causing a false error state if the assigned value differs from the
actual.
