Parameter Description
Parameter Description
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:
(3) Three-wire control mode 2 (with self maintaining function):K1: STOP signal, normally closed. If it is
open, the inverter will stop. K2: RNU signal, normally open, and the pulse signal are active.
