GD DISABLED X AGPS power supply of parallel connected R8i
inverter module has been switched off during
run. X (1...12) refers to inverter module
number.
ID RUN FAIL Motor ID run is not completed successfully.
(FF84)
IN CHOKE TEMP Excessive input choke temperature
(FF81)
3.17 FW 5 bit 5
INT CONFIG Number of inverter modules is not equal to
original number of inverters.
(5410)
03.17 FW 5 bit 10
INV DISABLED Optional DC switch has opened while unit was
running or Start command was given.
03.17 FW 5 bit 7
(3200)
INV LIMIT The fault is generated when the drive has hit
TORQUE INVERTER CURRENT LIMIT or IPP
(FFBF)
OVERTEMP ALM is active and a period of 200
ms has elapsed. The fault condition is only
3.33 CraneFW bit 5
checked when the generating power is more
than 10% of motor nominal power and the
speed is greater than 5% of the maximum
speed.
WHAT TO DO
Check CH2 communication, communication
settings.
Check CH2 communication, communication
meetings.
Check CH2 communication, communication
meetings.
Check CH2 communication, communication
meetings.
Check Safe Torque Off circuit.
Replace AGPS board of R8i inverter module.
Check maximum speed (parameter 20.02). It
should be at least 80% of motor nominal speed
(parameter 99.08).
Stop drive. Let it cool down.
Check ambient temperature.
Check that fan rotates in correct direction and
air flows freely.
Check status of inverters. See signal
APPL CONTROL WORD.
Check fibre optic cables between APBU and
inverter modules.
If Reduced run function is used, remove
faulted inverter module from main circuit and
write number of remaining inverter modules
into parameter 95.03 INT CONFIG USER.
Reset drive.
Close DC switch.
Check AFSC-0x Fuse Switch Controller unit.
Check the Speed controller torque settings.
Check torque, speed, power limit settings.
