5.3.1
Type of Control:
V/F 60 Hz - Operation
Via Keypad (HMI)
The
V/F or Scalar
Control is recommended in the following cases:
Several motors driven bythe same inverter;
Motor rated current lower than 1/3 of the inverter rated current;
For test purposes, without a motor connected to the inverter.
The V/F Control can also be usedin applications that do not require fast dynamic
responses, accurate speedregulation or high starting torque(speed error will be
a function of the motor slip).
When parameter
P138
(Rated Slip) is programmed, speed accuracy of 1 % can
beobtained.
Thesequence belowis valid forthe Connection1(refer to
item
3.2.7).
Theinverter
must be already installed and powered up accordingto
c
hapter 3
and
item
5.2.
