Strt
• IGBT test
nO
nO
YES
• No test
• The IGBTs are tested on power up and every time a run command is sent. These tests cause a slight
delay (a few ms). In the event of a fault, the drive will lock. The following faults can be detected:
- Drive output short-circuit (terminals U-V-W): SCF display
- IGBT faulty: xtF, where x indicates the number of the IGBT concerned
IGBT short-circuited: x2F, where x indicates the number of the IGBT concerned

YES
• Fault ignored. This configuration is the only one possible if AI1 current scaling parameter of 0% CrL1

To assign fault inhibit, press and hold down the “ENT” key for 2 s.
• Function inactive
• L1h: LI1 active high
• L2h: LI2 active high
• L3h: LI3 active high
• L4h: LI4 active high
CAUTION
RISK OF EQUIPMENT DAMAGE
Inhibiting faults results in the drive not being protected. This invalidates the warranty.
Check that the possible consequences do not present any risk.
Failure to follow these instructions can result in equipment damage.
To change the assignment of this parameter press the “ENT” key for 2 s.
Parameter that can be modified during operation or when stopped.
