3.2.11 Operating state indicator lights
Fundamentals
The operating state indicator lights of the drive are tested.
Test procedure
During the various tests, different operating states arise. The signaling of the following states
is recorded during the test.
● Fault (red)
● Alarm (yellow)
● Drive in Operation (green)
● Drive ready (white)
● Local operation (white)
Result
The test is passed if the operating state indicator lights light up in accordance with the operating
states.
3.2.12 Digital inputs and outputs for line synchronization
Fundamentals
