Need assistance with KONE TMS600 with V3F80. error 17 - current detected on Transistor bridge after drive has stopped. Happens in both directions, any or all floors. Lift slows down normally, stops and drive fault led lights up. After reset, lift relevels and faults again.
Any assistance appreciated.
