Meaning: Driver release driver: VZA controls driver but driver checkback signal missing.
Effect: Driving switched off (drive, Mikropils, brake)
Possible cause: driver on SK-VZA defective.
Measure: status analysis MZ-100, visually inspect SK-VZA, replace if necessaary. Before starting check the protection circuit of the drive contactors.
VZA: is the driver compartment processing unit
Also check the microfuses. The cards in the VZA and VZK are interchageable, so you might be able to identify a faulty card by swapping. There are some measures to be taken before swapping. If you need these email me.

The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
