EM500 Open-Loop Vector Control Inverter User Manual Terminal RUN: Xi=1, Run Terminal “RUN” Terminal Forward/Reverse (F/R): Xi=2, Direction R/F There are two terminal control modes, 2-wire sequence and 3-wire sequence. 2-Wire Sequence: F00.03=0: Terminal RUN, Forward/Reverse (F/R) ON/OFF of terminal RUN controls the start and stop of inverter and OFF/ON of terminal F/R controls the forward/reverse of inverter; if F00.21 is set as 1 and reverse is prohibited, terminal F/R is disabled. By selecting the ramp-to-stop for the stop mode, the logic diagram is shown in Figure 7-1 (b). F00.03=1:
Terminal RUN forward, F/R reverse ON/OFF of terminal RUN controls the forward running and stop of inverter and ON/OFF of terminal F/R controls the reverse and stop of inverter. If terminals RUN and F/R are on, inverter stops. If reverse is prohibited, terminal F/R is disabled. When selecting the ramp-to-stop, the control logic of inverter Forward/Reverse is shown in Figure 7-1 (d).
