AD - Analog Deadband

Compatibility: All stepper drives and SRV 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 denes 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.
