[Ld/Lg Degrees]
If [Ld/Lg Freq] and [Ld/Lg Degrees] are set to
non-zero values, a lead/lag filter (one pole, one
zero) is additionally inserted into the feedback
path of the velocity loop. This filter can be used
to enhance the stability of the loop in the
presence of load resonances.
This parameter specifies the amount of phase
shift that occurs at the lead/lag center frequency.
A negative value specifies a lag, while a positive
value specifies a lead.
In most cases, this filter will not be needed.
[Ld/Lg Freq]
This parameter specifies the center frequency of
the lead/lag filter in the velocity feedback path if
employed (see [Ld/Lg Degrees]. If set to zero,
the filter is disabled.
In most cases, this filter will not be needed.
[Line Voltage]
This parameter selects input line voltage being
used. It affects motor velocity ratings and must
be configured prior to selecting motor types.
This value is set automatically in all Smart Power
22 kW systems and 5 and 10 kW (Series C or
later) systems.
[Max Bandwidth]
After an auto tune, this parameter displays the
maximum system bandwidth that can be
achieved with the machine mechanics.
