Hi All, thanks for the suggestions, the drive is ok we have had this running for two days on a Kone test rig without fault,
Adding weight to the car doesn't really make sense to me as the car is running through in both directions, so i would assume it will make it run through worse in down.
Not changed contactors but they are energising and deenergising correctly and have positive activation of all contacts, no voltage drop or or high current demands.
From the schematics it appears that the car top board for the proxi switches is just a pass thru to the trailers so i will go back today and bridge this direct to trailers, but we do appear to be getting the signals correctly to the controller as it is but at this point anything is worth a try.
Completes a shaft learn without fault.
Manually checked rope slip and we have none, ie line on sheave and rope, run up and down a few times and they still correlate.
Checked brakes appear ok, but again do not see how an issue here would cause overtravel, under yes if it was not lifting.
Not noticed a parameter to check slip through the display, can you tell me the param ?
