Load Test Without Motor; Display Devices In The Cabinet Door - Siemens SINAMICS PERFECT HARMONY GH180 Reference Manual

Tests
3.2 Function test
Test procedure
The test is carried out with reduced power across an inductive load.
1. The drive is switched on.
2. A fiber-optic cable connector of a gating module is withdrawn for each phase.
3. The fiber-optic cable connector of an additional gating module is withdrawn.
Result
The test is passed if the appropriate messages are displayed on the test station computer.
3.2.26

Load test without motor

Fundamentals
The internal measuring device of the drive is checked for an inductive load. The calibrated
measuring equipment is used as reference.
When testing a version with 60 Hz input transformer on a 50 Hz line supply, the power is
reduced.
Test procedure
1. The drive is switched on in a test mode.
2. The inverter is enabled.
3. The rms values of voltage, current, apparent and active power are measured at the input
Result
The test is passed if the values displayed on the test station computer match the reference
values with a tolerance of ±5 %.
3.2.27

Display devices in the cabinet door

Fundamentals
Three display devices are mounted in the cabinet door of the control section. During the "Load
test without motor", a check is made whether the displayed values correspond to the measured
values of the calibrated measuring equipment.
