generated by FWD or REV, and they control the
running direction. During running, the terminal
Sin should be closed, and terminal FWD or REV
generates a rising edge signal to control the
running and direction of VFD; the VFD should be
stopped by disconnecting terminal Sin.
Sln: 3-wire control, FWD: Forward running, REV:
Reverse running
Note: In the 2-wire running mode, when the
FWD/REV terminal is valid, but the VFD stops
because of the stopping command from another
source, even when the control terminal
FWD/REV keeps valid, the VFD does not run
after the stopping command is terminated. Only
when FWD/REV is re-triggered, the VFD can
start again, for example, the PLC single-cycle
stop, fixed-length stop and terminal-controlled
valid STOP/RST stop (see P07.04).
The function codes define the corresponding
delay time of electrical level change when the
programmable terminals are switched on to
