When touching any button in the screen panel, 10KEY screen comes out for inputting values.

(1) Controller selection: Select a controller between operator and remote controller.

0: [Displays ‘Operator’] takes controlling values through operator. (called as LOCAL

mode)(Refer to operation controlling screen panel).

1: [Displays ‘TM’] takes controlling values through external analog input or contacts.

(Called as ROMOTE mode)(Refer to group A screen 2).

(2) Base frequency: set base frequency. Usually rated frequency of the motor is selected for the

base frequency. [Reference2].

(3) Maximum frequency: set maximum frequency of inverter output voltage. [Reference2].

(4) Acceleration pattern: set pattern for acceleration in accordance with the loaded value.

0: [displays ‘Line’] acceleration pattern is linear as shown in figure 15.

1: [displays ‘S’] acceleration pattern is S-shaped curve as shown in figure 15.

2: [displays ‘U’] acceleration pattern is a U-shaped curve as shown in figure 15.

3: [displays ‘RU’] acceleration pattern is a Rerversed U-shaped curve as shown in figure 15.

[Reference 2]

☞ Base frequency: the frequency that generates maximum output voltage. Usually rated frequency

of the motor is set as base frequency.

☞ Maximum frequency: maximum frequency that can operate motor. Constant voltage is generated

beyond base frequency as shown below.
