Understanding the Auto-tuning Procedure
Inverter Dgn1 (parameter 174) is defined as follows:
Bits 14 and 15 are reserved.
Inverter Dgn2 (parameter 175) is defined as follows:
If any hardware fault occurs during the open transistor testing, then
the following occur:
•
The hardware fault is saved.
•
A phase-to-phase fault is set.
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.
When this bit
is set (1):
Then:
0
Transistor U upper shorted.
1
Transistor U lower shorted.
2
Transistor V upper shorted.
3
Transistor V lower shorted.
4
Transistor W upper shorted.
5
Transistor W lower shorted.
6
The current feedback phase U offset is too large.
7
The current feedback phase W offset is too large.
8
Transistor U upper open.
9
Transistor U lower open.
10
Transistor V upper open.
11
Transistor V lower open.
12
Transistor W upper open.
13
Transistor W lower open.
14
Current feedback phase U open.
15
Current feedback phase W open.
