5. DESCRIPTION OF PARAMETERS
This manual only includes the parameters concerning the application (menu 5). For all other parameters
reference should be made to the "Description of functions and list of parameters" manual.
5 – LIFT
The LIFT menu displays the parameters concerning the LIFT function in the configuration with internal
positioning device (EPC).
All these functions are installed in the ADL300 series of drives as "Application 2".
To enable the function the
558 Sel Applicazione
parameter must be set to 2 (see ADL300 FP Functional
Parameter manual).
05.01 – MECHANICAL DATA
The parameters described in this menu are used to define the mechanical and physical characteristics of the
system.
Mechanical constants
The mechanical constant defines the relationship between motor rpm and the distance travelled by the lift
car.
There are two ways of calculating the
ConstMech
depending on the method of transformation that is used.
- Direct mode
:
Mechanical constant
= System speed /(Full scale speed/60)
- Mechanical data
:
Mechanical constant
= (π *Pulley diameter)/ Reduction gear ratio
The mechanical constant is calculated when the drive is switched on and re-calculated whenever changes
are made to one of the relative parameters (
Mechanical calc mode, Contract speed, Pulley Diameter,
Gearbox ratio
).
The method used to calculate the mechanical constant can be chosen regardless of which control mode has
been selected (
Flux vector OL
,
Flux vector CL
) or of the unit of measure to be used.
Weights and inertia
Once the system's mechanical characteristics have been entered the total inertia applied to the motor can be
calculated.
When these parameters are changed the calculated inertia value is automatically saved in the
Comp inerzia
parameter in order to perform correct inertia compensation.
The system displays the inertia value that can be entered in the
Inertia
parameter in the SPEED REG
GAINS menu to calculate the speed loop parameters more accurately.
This operation is performed automatically when PAR
11162 Calc spd reg gain
is enabled.
