Other errors 1
E50 (Bit 11) Velocity error, trolley
The trolley does not move, moves too fast or in the wrong direction. The error is triggered when:
● The output velocity is > 10% of the maximum velocity (P0) and the crane is not moving or
moving in the wrong direction
● The difference between the output velocity and the actual velocity > 20% of the maximum
velocity (P0) (e.g. defective drive)
The error appears with a delay of approx. 3 s. The error message is acknowledged when the
trolley moves.
The causes of these errors can be:
● Defective encoder
● Faulty connection to the drive
● Brake is still closed
The error is not signaled when the following error parameter of the drive (P161) is set to zero.
Error type:
Error
Remedy:
Check actual velocity and output velocity
E51 (Bit 11) Velocity error, hoist
The hoist does not move, moves too fast or in the wrong direction. The error is triggered when:
● The output velocity is > 10% of the maximum velocity (P40) and the crane is not moving or
moving in the wrong direction
● The difference between the output velocity and the actual velocity > 20% of the maximum
velocity (P40) (e.g. defective drive)
The error appears with a delay of approx. 3 s. The error message is acknowledged when the
hoist moves.
The causes of these errors can be:
● Defective encoder
● Faulty connection to the drive
● Brake is still closed
The error is not signaled when the following error parameter of the drive (P164) is set to zero.
Error type:
Error
Remedy:
Check actual velocity and output velocity
E52 – E57 reserved
E58 (Bit 21) Initial velocity to start semi-automatic mode (SAM)
The initial velocity when automatic travel starts in SAM mode is too high.
