4. Parameter description
Parameter
Note: 1. The default values are: P.80=2
（
RL
），
P.81=3
（

）
，
P.82=4
（

）
，
P.83=0
（
STF
），
P.84=1
（
STR
），
P.86=0
（
RES
），
P.126=5
（
AU
），
P.127=8
（
RT
）
，
P.128=7
（
MRS
）
.
2. When changing the value of P.80~P.84
、
P.86
、
P.126~P.128
，
the functions of the terminals are changed.
For example, P.80=2 means that the function of
RL
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):
(1). two-wire control mode1:
(2). two-wire control mode2:
(3). three-wire control mode2 (with self maintaining function):K1: STOP signal, normally close. If it is
open, the inverter will stop. K2: RNU signal, normally open, and the pulse signal is active.
(4). three-wire control mode2 (with self maintaining function):K1: STOP signal, normally close. If K1
opened, the inverter will stop. K2: RNU signal, normally open, and the pulse signal is active.
If the
external terminal corresponding related parameters settings for 39, when reversing, the motor will
stop until you start again.
