In Case Of Problems Adjust The Following Vdl200 Parameters - gefran AGy-L Series Installation And Commissioning Manual

6 In case of problems adjust the following VDL200 parameters

Problem
At Start there is a delay to
release the brake and there
is a car shock.
At Start the acceleration is
to sharp.
After the start the
acceleration is to sharp.
The first phase of the
deceleration is to sharp.
The deceleration to
approach the floor is to
sharp.
During the landing phase
the speed is not smooth but
with jumps.
At Stop there is a delay to
close the brake.
At Stop there is a shock.
For elevator in close loop,
during the travelling at the
rated speed there are
vibrations.
The short floor is not
optimized.
Rollback at Start for Open
Loop Control or the car is
not able to start.
Replace AGy-L by VDL200
Cause
The Motor starts running when the
brake is not completely released or
runs against the brake
The Acc ini Jerk value is too high
The linear acceleration value is too
high
The Dec ini Jerk value is too high
The deceleration value is too high
The configuration of the brake
closure timing is not optimized
The brake closes before of the
motor stop.
The Speed control loop is not well
set.
The parameters related to the short
floor are not well optimized.
There is no enough current.
