Bit 1
Synchronizing voltage not present / failed
→
check the synchronizing voltage connection (hardware)
PA6
Bit 2
∅
Erroneous synchronizing voltage
Frequency step > 10% / periods
→
check the synchronizing voltage (hardware)
PA6
Bit 3
∅
Zero crossovers UL1-2 missing (Sitor)
only, if the signal was present once.
→
check the line supply connection and initialization connection PA6.INV
PA6
Bit 4
∅
Zero crossovers UL1-3 missing (Sitor)
only, if the signal was present once.
→
check the line supply connection and initialization connection PA6.INV
PA6
Bit 5
∅
Rotating field error = no clockwise rotating field of Vsyn.,
or both zero crossovers missing.
(dependent on the mode: INV)
→
check the line supply connection and initialization connection PA6.INV
PA6
Bit 6
∅
Undervoltage (Sitor).
(dependent on the mode: UNM)
→
check the line supply values and connector SOL.UNM
SOL
Bit 7
∅
Logical 0
Bit 8
Pulse inhibit, software
(.IPL = 1) + hardware command: Total pulse inhibit
SOL
Bit 9

(SOL.IF1= 1)
SOL
Bit 10
∅
Fuse monitoring (Sitor)
→
check for fuse failure
SOL
Bit 11
∅
Temperature monitoring (Sitor)
→
check for overtemperature
SOL
Bit 12

+ hardware command: Total pulse inhibit
→
ITDC-X5:10 > 15 V
=
ˆ
enable the pulses
SOL
Bit 14
Excitation current fault
(optional for SITOR set 6QG3x with excitation option)
Cause: FCS.FC > 5% and field current actual value < 3% FCS.ARC
→
check the field control/connection
FCS
Bit 15
Hardware Watchdog ITDC + hardware command: Total pulse inhibit
Causes: Defective module,
→
replace the module
Task overflow in the PMx
→
change the application software
SOL
Bit 16
Hardware command: Total pulse inhibit (ITDC-X5:15)
→
remove the fault statuses
