Hi,
We have a EOT crane which has 3 hoists (30T/60T/30T). The issue is when we give command for Hoist Up or Down the the motor runs for few rotations then stops completely and after full opening of brake it starts running again. Not sure how this is happening.
There are 2 Thruster brakes for each hoist, their opening and closing works together. The brake open/close command is given by drive output relay. The drive is ATV71 - Schneider which has inbuilt brake logic parameters.
We never faced such problem . This is something new.
