We have a 50-04 vvvf regen drive that keeps failing the nts test. (Tst1)The car doesn’t seem to be clamping hard enough and it ends up on the final limit. Tried relearning the hoistway and a back up scan. Have about 5” between the normal and final limits. Tried adjusting the Decel but car just doesn’t seem to clamp. Fails in both directions. Car runs on auto with capacity and has no problem hitting floor levels. Any ideas on how to get the car to stop sooner on this test thanks. IMs says car is moving 39fpm when Dlb opens.

Re adjusted my direction limits and that made a big difference still won’t hold back capacity on Nts test also
Found when it leaves the bottom floor with capacity in the car it shuts down on a 693 drive fault?
