05.04 – MECHANICAL DATA
The parameters described on this menu are used to define the system's mechanical and physical characteristics.
Mechanical constants
The mechanical constant defines the link between motor revolutions and the space traveled by the car.
There are two ways to calculate ConstMech bases on the conversion method used.
- Direct method:
- Mechanical data:
The mechanical constant is calculated when the drive is switched on and is recalculated each time one of its defining
parameters is changed (Mechanical calc mode, Full scale speed, Contract speed, Pulley diameter, Gearbox
Selection of the mechanical constant calculation method is independent of the type of control selected
vector OL, Flux vector CL,
Weight and inertia
Entering the system's mechanical characteristics lets you calculate the total inertia applied to the motor.
After these parameters are changed, the inertia value calculated is automatically saved in the
correctly compensate inertia.
The inertia value that can be entered in the
precise calculation of speed loop parameters. This can be done automatically by enabling PAR 11162
gain.
Menu Par Description
Contract speed
5.4.1 11006
Car speed at Base frequency. Represents system speed and is also used to calculate the mechanical constant.
Associating car speed in m/s to speed full scale (PAR 628) gives the conversion coefficient (mt/rev).
Menu Par Description
5.4.2 11008 Mechanical calc mode
Setting of calculation mode for unit of measurement, based on car and motor speed (Direct method) or based on
mechanical ratios (Mechanical data mode).
