Have a Kone KDL16 giving us hell. These are the symptoms:

Run on inspection up or down brake and ebrake picks
Car shutters floats and drifts up slightly. 102 flt xtra 2002.
Drive has been changed with known good drive from elevator in bldg. Motor encoder changed with known good encoder from same running elevator in bldg. LCECPU and Adon both from running car. Drive setup 6_60 = 10.25. Also tried setting the drive up with custom motor nameplate data 6_60 = 88.88. Loadweigher is at 0% empty car. Main line voltage is at 490 vac tapped to a step down transformer 415 vac to the kdl16L drive. Motor phase to phase is .2 ohms. Phase to ground = O.L. This elevator will run open loop just fine 6_65=0, but if you Choose 6_65=-2 or 6_65=2 car shutters, floats and drifts up.

Any ideas?
