STF/STR
+STOP
In ‘external mode’, it is used
with RUN. The inverter runs
reverse when STF/STR is
‘on’, stop when STF/STR is
‘off’. If you need runs
forwards, you should RUN
again.
Note: 1. The default values are: P.80=2 (RL), P.81=3 (RM), P.82=4 (RH), P.83=0 (STF), P.84=1 (STR), P.86=30
(RES).
2. When changing the value of P.80~P.84, P.86, the function of the terminals is changed. For example, P.80=2
means that the function of M0 is RL, but if P.80=8, its function changes to RT, as a second function
selection terminal, P.83=0 means that the STR terminal is chosen as running forward terminal, when
P.83=6, its function changes to ‘OH’, it is then external thermal relay terminal.
3. Wiring for external thermal relay (OH): In traditional wiring,
a thermal relay is added to the motor to prevent the motor
from being too hot. Its wring is on the right figure. When
the external thermal relay is separated, the inverter will
indicate alarm, and ‘OHT’ will be displayed on the screen.
4. There are 4 kinds of operating modes to drive the inverter (‘1’ means the terminal closes, ‘0’ means the
terminal opens, X=0,1,2,3,4,6):
