40 ● AW DMC-40x0 Command Reference
AW
FUNCTION: Amplifier Bandwidth
DESCRIPTION:
The AW command accepts the drive voltage (volts) and motor inductance (millihenries) and uses
the current loop gain setting (AU) as the default and then reports the calculated bandwidth.
The user can check how the amplifier bandwidth is affected by changing the n parameter.
The AU command uses the transfer function for the AMP-430x0 for the calculation of the
bandwidth.
ARGUMENTS: AWx = v, l, n where
x = Axis designator
v = Drive voltage in Volts
l = Motor inductance in millihenries
n = optional current loop gain setting (1 or 0)
