Description
3: Three-wire control 2. This mode defines
Sin as the enabling terminal, and the
running command is generated by FWD or
REV, but the direction is controlled by both
FWD and REV. During running, the Sin
terminal needs to be closed, and terminal
FWD or REV generates a rising edge signal
to control the running and direction of the
VFD; the VFD needs to be stopped by
disconnecting terminal Sin.

Sin: Three-wire control; FWD: Forward
running; REV: Reverse running
Note: For two-wire controlled running
mode, when the FWD/REV terminal is
valid, if the VFD stops due to a stop
command given by another source, the
VFD does not run again after the stop
command disappears even if the control
terminal FWD/REV is still valid. To make
the VFD run, you need to trigger FWD/REV
again, for example, PLC single-cycle stop,
fixed-length stop, and valid STOP/RST
stop during terminal control. (See P07.04.)
