During erection, jib would go up, but mast would not. Pressure would build on hydraulics, but mast wouldn’t move.
Counterweight sensor was not reading. Jumper 18A -18, and mast would go.
Crane starts but will not swing
Frequency drive starts and immediately shuts down, with code AFE1 (emergency stop)
Operator sent over following screen with active fault
Had to force K600M to stay energized (pressing in on the blue tab behind the plastic cover) to access drive and turn slew motor encoder to Partial Open Loop. (74.12)
Crane would start up and run, but operator didn’t like swing characteristics. To be expected, the slew drive is no longer receiving feedback from the motors, and is estimating speed and direction.
Replace slew motor encoder, and all is good.
**Note from Denis** Make sure and protect the shield with heat shrink or tape, as it can cause a short
If the motor encoder is internally shorted, the drive may not operate in partial open loop as it tries to protect itself. If this is the case, unplug the 2 connectors from the slew drive and reprogram parameter 90.46 to Force Open Loop.
Error messages on CCs would be Slewing Frequency Converter lost (00011.20482) or Slewing Frequency Converter not detected (00011.20481)

Plug Ins not Working In Cab
Operator called and Plug Ins inside of cab not working. Also, had a number of errors are were Open Circuit.
Q104F Circuit Breaker was tripped. (Only blue breaker in the cabinet)
Trolley starting, but suddenly stopping
Trolley position could be set during Teach In, because it bypasses all encoders, but after completion and it Normal Operation Mode it would stop suddenly. Found encoder box was not adjusted properly and the gear whell on the encoder box was not turning with trolley winch. Readjust, and had to re-teach.
Could not calibrate Moment sensors
During erection, could not validate 0 moment in Teach In. Both moment sensors were reading 0 mA. If moments sensors are too close or too far away, they will be “out of range” and read 0 mA. Need to be adjusted by gap once the crane is in the air and all of the weights are in.
5.5 mm is what it needs to be set at.

Top Zone Igo T85A
Crane would not accept P1 or P2 in Top Zone.
Need to verify that the crane is reading the correct angle position and it moves with crane. This is displayed on the remote by pressing the arrow keys. If not, need to redo 1.5 times rotation and set origin, reference manual if needed.
Per Tomas, Set P1, set P2 and then press <ENTER> through Stopping Angle. Press <ESC>, <ESC>, ESC>, and turn of remote and then crane power. Restart crane, and it should work.
Assistance Mode Displayed
When starting crane Assistance Mode was displayed on processor. Found 1 of the angle sensors on cathead was backed off 1/2″. Readjusted, all is working well.
Tomas says crane needs to see hook height, trolley position and jib angle. Can see on Erection Aid and J3 inputs (3211)
Crane will go into Assistance Mode if 1 of 4 sensors are not reading correctly. 1) Jib Angle – To check, go into Erection Aid (Menu 6), page 1
2) Trolley position – Menu 3211 and Input/Output J3 (not J2/J3)
3) Hook position – Same as above
4) Load on hook – Menu 3211 Input/Output J4 B400Nx

HUP Sensor List
Weathervane on releasing on Hup (Slew Brake not engaging)
Need to raise handle on brake and slide cam plate (lock plate) into position. Lift up on brake handle, and the plate should return to the “unlocked” position automatically.
Video showing proper operation
If not, remove weathervane coil plate with the 2 bolts, but be careful as the return spring is underneath it. Remove the 4 screws holding the lock plate in place and clean bottom of lock plate and surface below it on the brake coil. When reinstalling, make sure that the nut on the weathervane coil is not too tight, as it can interfere with free movement.
