(2) LED operation panel (U30 V24OP2)
4-4 Selection of control modes
With the VAT300, four control modes and two overload modes can be selected. These are set with the
parameter C30-0 (control mode selection).
* C30-0 is set with a 2-digit value (f1, f0).

Checking the operation after
power ON
Turn the power ON.
All LEDs on the numeric display will turn ON for
a short time, and then "
" " and "
The "LCL" and "Hz" LEDs will also turn ON.
There are four VAT300 motor control modes. Refer to the following table, and select the mode
which suits the application.
Control mode
1) V/f control
2) IM speed sensor-less
vector control
3) IM vector control with
speed sensor
4) PM motor control with
sensor
(Note 1) Refer to Table 7-1-a of ST-3450 for details on the speed detection options.
The following two modes can be selected according to the load being used. If the load and device
capacity do not differ, the device could be overloaded. Refer to the following table, and select the
mode that matches the load being used.
Control mode
1) Normal-duty setting
2) Heavy-duty setting

Explanation
The IM is controlled keeping the ratio of voltage and
frequency constant.
The IM is vector-controlled without a speed sensor.
The speed can be controlled.
The IM is vector-controlled with a speed sensor.
This mode is used when a fast speed response or
torque response is required.
The speed detection option 1 is required. (Note 1)
The PM motor is vector-controlled.
The motor can be operated at a higher efficiency than
IM.
A speed detection option which matches the sensor
(encoder) being used is required. (Note 1)
Explanation
Select this when the maximum load rate in respect to the
rated load is low.
The overload standard will be 120% of the device's rated
current for one minute.
Select this when the maximum load rate in respect to the
rated load is high.
The overload standard will be 150% of the device's rated
current for one minute.
