Host Command Reference
AD - Analog Deadband
Compatibility: All stepper drives and SV servo drives
Affects:
Analog input
See also: CM command
Sets or requests the analog deadband value in millivolts. The deadband value is the zone around the “zeroed”
value of the analog input. This deadband defines the area of the analog input range that the drive should interpret
as “zero”. This zero point can be used as the zero velocity point in analog velocity mode, or as the zero position
point in analog position mode (see CM command). The deadband is an absolute value that in usage is applied to
either side of the zero point.
Note that in Analog Positioning mode (CM22), the AD setting is used as a hysteresis value rather than a standard
deadband setting. As such, it will work over the entire analog range, not just at zero volts.
