Initialization procedure for calculating rope length
This operation has to be done only when the machine is commissioned:
Attention: when setting a default load for drive parameters, you have to reload the application parameters
(see the COMMISSIONING PROCEDURE).
If the distance between the hook and the center of gravity of the load changes significantly (replacement of
anchor ropes, etc.), you will have to change the "H&C SERVICE\Measure load" parameter (IPA11200).
You can use two ways to initialize the rope length calculation procedure, depending on whether the mechanical
ratio of motor rpm / distance is known or not:
PROCEDURE for known conversion ratio
Write coefficient of ratio
motor rpm/distance in "H&C
SERVICE \ mpr" parameter
(IPA11148).
Bring hook to a "known
position" and write distance
(expressed
in
meters)
between hook and rope
winder drum or from pulleys,
if present (C) in "H&C
SERVICE \ Known position"
parameter (IPA 11198).
This
operation
lets
software calculate its position
on the rope.
On Hoist only: If distance is
not known, see chapter
"Calculation of rope length"
and enter the result in the
"known position" parameter.
In
the
"H&C SERVICE
\Measure load" parameter
(IPA11200),
enter
distance between the hook
groove and the hypothetical
center of gravity of the load
(D).
Save and reset the drives.
