STT - STO Self-Test Result
Alias: - HexCode: 70 CANOpen id: -
Description:
Returns the result of the latest executed STO Self-Test process. This process is applicable
only on motor controllers with STO circuit implemented on their board. If the result is
not successful the Respective STO Fault bit in the Fault Flags is set. The fault is triggered
when:
Any of the transistors or other component of the STO circuit is damaged.
Any of the Power MOSFETs is damaged.
The respective jumper is placed on the board.
Syntax Serial: ?STT xx
Argument: Fault Indication
Min: 1 (STO Result) Max: 2 (MOSFET Result)
Syntax Scripting: result = getvalue(_STT, xx)
Reply:
If xx = 1 (STO Result)
STT=ff Type Singed 32-bit Min: -1 Max: 4
Where ff=
-1: The test is in process
0: Test successfull
1: STO1 failed the test
2: STO2 failed the test
3: Test failed using input values
4: Test passed using input values, but cannot continue test since STO is triggerred. Any of
the Power MOSFETs is damaged.
If xx = 2 (MOSFET Result)
STT = f1 + f2*2 + f3*4 + ... + fn*2^n-1 Type: Signed 32-bit Min: 0 Max: 4095
Where:
f1 = Top MOSFET of U1 phase is damaged
f2 = Bottom MOSFET of U1 phase is damaged
f3 = Top MOSFET of V1 phase is damaged
