value.
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 functions of the terminals will be 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 and becomes the external thermal relay terminal.
3. External thermal relay (OH) wiring: In traditional wiring, a thermal relay is added to the motor to prevent
the motor from being too hot. Its wring is presented in the right figure. When the external thermal relay is
separated, the inverter will induce the alarm, and ‘OHT’ will be displayed on the screen.
4. There are four kinds of operating modes for driving the inverter (“1” means close terminals, “0” means open
terminals, X=0,1,2,3,4,6):
(1) Two-wire control mode 1:
(2) Two-wire control mode 2:
