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
Number of encoder pulses (value indicated on encoder type
plate)
Value
referred to the data of the encoder type plate:
TTL: +5V encoder (supply voltage at
terminal 30)
HTL: +15V encoder (supply voltage at
terminal 31)
Sine: +1Vss sine encoder (supply voltage
via D-SUB socket)
Please make sure that the supply voltage connection of the
encoder is connected to the correct VVVF controller terminal (terminal 30 =
+5V, terminal 31 = +15V).
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.
