General settings (Open Loop)

 

In order for the motor control to work at the optimum operating point, the system data must be entered:

 

I_MOT

Rated current of motor (value indicated on motor type plate).

U_MOT

Rated voltage of motor (value indicated on motor type plate).

n_MOT

Rated speed of motor (value indicated on motor type plate).

Please enter the asynchronous speed (rated speed of motor). If you enter the synchronous speed (e.g. 1500 1/min in the case of 4-pole motors with a rated frequency of 50 Hz), the VVVF controller will not work properly.

f_MOT

Rated frequency of motor (value indicated on motor type plate).

cos_phi

Power factor of the motor. The value given on the type plate of the motor must be multiplied by 100. Example :

Type plate: cos(phi)           = 0.8

ðFRC-F/FRC-Q                = 80

 

 

 

If "mm/s" is selected as the unit, the follwoing parameters which are required for the conversion are displayed additionally:

trnsmiss (* 100)

Here, you must enter the transmission * 100. Example :

Transmission = 53:2

ð Entered value 26.5 * 100 = 2650

pull. diam

Here, you must enter the pulley diameter in mm

susp dev

suspension

1  ð  1:1

2  ð  2:1

4  ð  4:1, ...
