5.2.3 Line monitoring OPT-D7

V1.3.1 Line Voltage
The measured line voltage rms value when using the OPT-D7 option board in slot C.
V1.3.2 Line Frequency Hz
The measured line voltage frequency when using the OPT-D7 option board in slot C.
V1.3.3 Synch Error D7
An error on voltage angles between the drive and the measurement taken by OPT-D7.
-3072...+3071 = -180...180 degrees.
If the value is not near to zero when running in AFE mode, the phase order may be wrong
even if the OPT-D7 frequency is correct (Error about 2047 = 120 degree). If measurement
is after Dyn11 transformer error is usually about 512 (30,0 Degree).
