Drive response window for internal line reference
Display Description
Phase angle no load
The phase angle difference measured between the
drive source voltage and the utility voltage. The utility
voltage was measured at the drive output. A positive
phase angle indicates the utility lags the drive source.
For a negative phase angle, the utility leads the drive
source.
Utility phase offset
Offsets consisting of the phase angle no load plus
phase compensation due to transformer loading.
Utility AC line The utility line voltage measured at the drive output.
Drive AC source The drive source voltage.
Utility volt scale Volt scale = Utility AC line voltage / Drive AC source
voltage
Drive response window for external line reference
Display Description
Phase angle no load
The phase angle difference measured between the
external reference and the utility voltage. The utility
voltage was measured at the drive output. A positive
phase angle indicates that the utility lags the external
reference. For a negative phase angle, the utility leads
the external reference.
Utility phase offset
Offset consisting of the phase angle no load plus
phase compensation due to transformer loading.
Utility AC line The utility line voltage measured at the drive output.
External reference The external voltage measured at the analog input.
Utility volt scale Set equal to 1.0 when using an external reference.
Ext ref Vpt scale Volt scale = Utility AC line voltage / External line
reference voltage
