(Some parameters can be changed.Refer to page 55 for the parameter list.)⋅ When "0" or "2" is selected for Pr. 79, the inverter entersthe external operation mode at power on. (When usingthe network operation mode, refer to page 291)⋅ When parameter changing is seldom necessary, setting"2" fixes the operation mode to external operationmode. When frequent parameter changing isnecessary, setting "0" (initial value) allows the operationmode to be changed easily to PU operation mode bypressing of the operation panel. When youswitched to PU operation mode, always return toexternal operation mode.⋅ The STF and STR signal are used as a start command,and the voltage or current signal to terminal 2, 4, multispeedsignal, JOG signal, etc. are used as frequencycommand.(5) PU operation mode (setting "1")Three-phaseAC power supplyInverterR/L1S/L2T/L3FR-DU07,,UVWMotor⋅ Select the PU operation mode when applying start andspeed command by only the key operation of theoperation panel (FR-DU07) or parameter unit (FR-PU04/FR-PU07). Also select the PU operation modewhen making communication using the PU connector.⋅ When "1" is selected for Pr. 79, the inverter enters thePU operation mode at power on. You cannot change tothe other operation mode.⋅ The setting dial of the operation panel can be used forsetting like a potentiometer. (Pr. 161 Frequency setting/keylock operation selection, refer to page 361.)⋅ When PU operation mode is selected, the PU operationmode signal (PU) can be output.For the terminal used for the PU signal output, assignthe function by setting "10 (positive logic) or 110(negative logic)" in any of Pr. 190 to Pr. 196 (outputterminal function selection).286
