★：
The jog speed setting mode is superior to other setting modes. That is, when the control
terminals FJOG and RJOG are enabled, the inverter will automatically change to the jog speed
setting mode, regardless of the current setting mode.

Operation method of inverter
The operation method of the inverter refers to the operating conditions for the inverter to
enable the running status. It includes: keyboard operation, terminal operation and
communication operation. Terminal operation is divided into two-line control (RUN, F/R) and
three-line control (RUN, F/R, Xi (i=1-5)) (change the definition of Xi to three-line operation
stop control). The control logic of this operation method is shown inFig. 1-6 (take the NPN
input mode as an example).
