Commissioning

2.14.3
To support commissioning the directions of field rotation of both voltages U1 and U2 are presented in the
measured values display window, as well as the currently active synchronizing fucntion group.

Min/Max Measurement Setup

Minimum and maximum values are calculated by the 7VE61 and 7VE63 and can be read out with the point of
time (date and time of the last update).
2.14.4.1

Functional Description

Minimum and maximum values of voltages U1, U2 and ΔU as primary values, of frequencies f1, f2 and Δf, and
the angle difference Δα, each with last update date and time designation. The selected group values are calcu-
lated and displayed. The resetting of the minimum/maximum values takes place automatically for each
successfully starting of a synchronization. Additionally, the minimum/maximum values can be reset via binary
inputs or, in the delivery status of the device, also via the F4 function key.
