Phase Offset Of The Output Voltage In The Three-Phase System; Local Control Via The Operator Panel - Siemens SINAMICS PERFECT HARMONY GH180 Reference Manual

3.2.7

Phase offset of the output voltage in the three-phase system

Fundamentals
A check is made whether the three phases of the output voltage have a 120° phase offset.
Test procedure
1. The drive is switched on.
2. The output voltages at measuring points VMA, VMB, VMC are displayed on an oscilloscope.
Result
The test is passed if the phase offset is 120°.
3.2.8

Local control via the operator panel

Fundamentals
With the drive in the local mode, a check is made as to whether it can be controlled from the
operator panel.
Test procedure
1. The drive is switched into the local mode using the "Local-remote switch".
2. The following operating states are set and monitored at the operator panel or at the test
Result
The test is passed if the corresponding operating states and specified values occur.
