Inverter Diagnostics Result #1 (parameter 258) and Inverter Diagnostics
Result #2 (parameter 259) contain the results of the transistor diagnostic
tests.
Important: Serious component failures may occur if unverified power
transistor fault conditions are ignored or tests are disabled
before you proceed to run the drive under load.
Inverter Diagnostics Result #1 (parameter 258) is defined as follows:
When this
bit is set (1):
Then:
0
A software fault occurred.
1
No motor is connected, or a bus fuse is open.
2
Phase U and W shorted.
3
Phase U and V shorted.
4
Phase V and W shorted.
5
There are shorted modules.
6
A ground fault occurred.
7
A fault occurred before the short module ran.
8
A hardware overvoltage fault occurred.
9
A hardware desat fault occurred.
10
A hardware ground fault occurred.
11
A hardware phase overcurrent fault occurred.
12
There are open power transistor(s).
13
There are current feedback faults.
Bits 14 and 15 are reserved.
