6.1.2. Description of Rectifier bridge faults
DISPLAY
DESCRIPTION
R1 I LIM FLT
Rectifier current has reached a dangerous level. Its value is above 220% of the drive rated current. Hardware
protection is activated instantaneously
R2 V LIM FLT
DC Bus voltage has reached a dangerous level >850VDC (Vn=400Vac) and >1250Vdc (Vn=690Vac). Hardware
Protection. Drive will turn off the output to the motor.
R3 SOFT CHARG
DC Bus voltage do not reach Vdc.
R4 OVERLOAD R+
Internal protection within the appropriate IGBT semiconductor has acted.
R5 OVERLOAD R-
R6 OVERLOAD S+
R7 OVERLOAD S-
R8 OVERLOAD T+
R9 OVERLOAD T-
R10 MULTI O.L.
R11 VIN LOST
Voltage input measure is lost.
R12 IMB V IN
Inverse Input voltage is greater than +30% of average input voltage for a time higher than 100ms.
R13 V LOST CAP
Capacitor voltage measure is lost.
R14 VBUS LOST
DC bus voltage measure is lost.
R15 SfCh CONTACT
The feedback contactor signal is lost. The softcharge contactor is faulty or the activation signal is lost.
The softchange contactor was connected when the order has been given. Take a look to the wiring (nonresettable).
R16 LCL TEMP
The LCL filter has reached a dangerous temperature level.
R17 VBUS LOW
Low bus voltage detected <450VDC (Vn=400Vac) and <800Vdc (Vn=690Vac)
R18 FIBR COMMS
CAN Fiber Optics communication failed.
R19 I IMB IN
Inverse input current has reached (G22.11.7x In) limit for a time higher than 10ms.
R20 GRND INPUT
Ground fault input current has reached (G22.11.8x In) limit.
R21 I LIMIT IN
Input current has exceeded the current limit set in „G22.11.5‟ for the time set in „G22.11.6.
R22 IGBT TMP
Rectifier bridge IGBTs temperature has reached 110ºC ( See SV7.4)
