T99 Hoist Encoder

Was setting up T99 It was erected ready to teach.  Have to put in your technician code to teach the crane on your remote.  Was teaching the Trolley and exempted it.  Went to the Hoist to teach its upper limit and would NOT exempt it.  It would not exempt 0 load as well.

 

Hup loses functions, drives shut down

Hup loses slew function sporadically, will sometime cause other drives to shut down with Cof fault. This is often an error with the slew motor encoder failing or shorting out. The drive sends a stop command AFE1 or 5091 to power down the drive which then shuts down the other drives.


The drive will often fault and shut down before registering a fault in the CCS. Check the fault history of the ACS380. If an encoder fault is present like 7301 – Motor Speed not detected,
Replace the motor encoder
If an encoder isn’t available you can remove the encoder wiring from the drive and it will default to estimated speed.

T85 starts and drives shut off

Slew, Trolley, and hoist drives begin start sequence, then power down. Check incoming power. It is possible L1 of the circuit isn’t there, but the other two legs will be the ones providing 48V and 24V to feed processor and start sequence. It will be backed up by the U100N not being powered.

Slow Trolley, Hoist

81K Crane hoist speed was slow. (no zones, Load plus was turned off) hoist speed was the same as if the micro movement button was pressed. The crane threw code E2647 DC undervoltage
Found the generator idle speed switch was at Low, flipped the switch to High restarted the crane.

How to move trolley in mounting

When in mounting to move trolley you need to push the auxiliary button on the side of the remote wait for the Hydraulic pump to stop and then you have functions of trolley in. In order to get trolley out you have to by pass all the sensors on the LOGO by holding down the down arrow button and the esc button.
