VLT® 5000 Crane
724 DRUM INERTIA 2
Value:
0 - 1 kgm
2
✭
Depends on unit
Function:
This parameter is used in the load estimator to
calculate the static load on the motor by setting
the inertia of the cable drum in gear 2.
725 GEAR RATIO 2
Value:
0 - 200
✭
Depends on unit
Function:
Set the ratio of the gear in gear 2.
The parameter is used in the load estimator to
calculate the static load on the motor.
726 GEAR INERTIA 2
Value:
0 - 1 kgm
2
✭
Depends on unit
Function:
Set the gear inertia in gear 2.
This parameter is used in the load estimator to
calculate the static load on the motor.
727 MEAN RADIUS 2
Value:
0 - 2 m
✭
Depends on unit
Function:
Set the mean radius in metres of the cable
drum with the gear in gear 2.
This parameter is used in the load estimator to
calculate the static load on the motor.
740 POWER LIMIT FUNC.
Value:
✭
0 (CONSTANT POWER)
[0]
1 (USER DEFINED)
[1]
2 (OFF)
[2]
Function:
With this parameter it is possible to choose
between a speed limitation based on constant
power or a speed limitation based on a user
defined profile, see figures below.
Description of choice:
The user defined profile is defined in par. 741 - 750.
NB!:
Note that it is important to set parameter 750
(N5) before setting parameters 741-749 in order
to follow the user defined curve shown below.
741 MECH. SPEED N1
Value:
RPM
✭
Depends on unit
Function:
Set the speed point for power at N1.
Description of choice:
This parameter is limited between nominal motor
speed and output speed high limit (par. 202)
742 POWER AT N1
Value:
kW
✭
Depends on unit
Function:
Set the output power at N1.
Description of choice:
This parameter is limited to be less than or equal
to the nominal power of the drive.
