In order for the motor control to work at the optimum
operating point, the system data must be entered:
Rated current of motor (value indicated on motor type
plate).
Rated voltage of motor (value indicated on motor type
plate).
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.
Rated frequency of motor (value indicated on motor type
plate).
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:
Here, you must enter the transmission * 100.
Example :
Transmission = 53:2
ð Entered value 26.5 * 100 = 2650
Here,
you must enter the pulley diameter in mm
suspension
1 ð 1:1
2 ð 2:1
4 ð 4:1, ...
For
more details, please refer to the VVVF controller manual.
