Info

In vector control, current feedback control is performed. In the current feedback control, the current is controlled with the difference between the motor induced voltage and the inverter output voltage. For a proper control, the inverter output voltage should be sufficiently higher than the motor induced voltage. Generally, the voltage difference is about 20 V for 230 V series, about 40 V for 460 V series. The maximum voltage the inverter can output cannot exceed the inverter input voltage. Configure these voltages correctly in accordance with the motor specifications. When enabling the vector control without speed sensor using a general-purpose motor, set the F05 (Rated Voltage at Base Frequency 1) data at the rated voltage of the motor. The voltage difference described above is specified by function code P56 (Induced voltage factor under vector control). Generally, there is no need to modify the initial setting. • Non-linear V/f Patterns 1, 2 and 3 for Frequency (H50, H52 and H65) If F05 (Rated Voltage at Base Frequency 1) is set to "0," settings of H50 through H53, H65, H66 and F06 do not take effect. (When the non-linear point is below the base frequency, the linear V/f pattern applies; when it is above, the output voltage is kept constant.) Data setting range: 0.0 (cancel); 0.1 to 500.0 (Hz) Set the frequency component at an arbitrary point in the non-linear V/f pattern. Setting "0.0" to H50, H52 or H65 disables the non-linear V/f pattern operation. • Non-linear V/f Patterns 1, 2 and 3 for Voltage (H51, H53 and H66) Data setting range: 0 to 240 (V): Output an AVR-controlled voltage for 230 V series 0 to 500 (V): Output an AVR-controlled voltage for 460 V series Sets the voltage component at an arbitrary point in the non-linear V/f pattern. • Maximum Output Voltage 1 (F06) Data setting range: 80 to 240 (V): Output an AVR-controlled voltage for 230 V series 160 to 500 (V): Output an AVR-controlled voltage for 460 V series Set the voltage for the maximum frequency 1 (F03).

F08 specifies the deceleration time, the length of time the frequency decreases from the maximum frequency down to 0 Hz. - Data setting range: 0.00 to 6000 (s) Under V/f control 4-37

E14 E15 ON ON When the terminal command JOG is ON, jogging operation is possible. (Data = 10) ( Refer to the description of C20.) When the terminal command STOP is OFF, the motor decelerates to a stop in accordance with the deceleration time for forced stop (H56). After the motor stops, the inverter enters the alarm state with the alarm er6 displayed. (Data = 30) 4-38
