4.1.3 Special conditions
Display Description
StP0
In V/f mode, STP0 comes
out at less than 1.3Hz
(50Hz set) or at less than
1.5Hz (60Hz set)
In SLV mode, STP0
comes out at less than
1Hz
StP1
1. If the inverter is set for
external terminal control
mode (00-02/00-03=1) and
direct start is disabled
(07-04=1)
2. The inverter cannot be
started and will flash
STP1.
3. The run input is active at
power-up, refer to
descriptions of (07-04).
StP2
1. If the Stop key is
pressed while the inverter
is set to external control
mode (00-02/00-03=1)
then‘STP2’flashes after
stop.
2. Release and re-activate
the run contact to restart
the inverter.
E.S.

input is activated the
inverter will decelerate to
stop and the display will

the display will flash
with b.b. message.
PdEr
PID feedback loss is
detected.
Alter
other errors show up in the
process of auto tuning.
OH3
If 08-10 = 3, When over
temperature is detected by
signal at terminal AVI
increasing above the
warning detection limit set
in parameter 08-15, then
the display will show
“OH3”(motor
over heat warning level)
and the motor will continue
to run.
Display Description
LOPB
Check if feedback value of
pressure is lower than limit
of minimum pressure
HIPB
Check if feedback value of
pressure is lower than limit
of maximum pressure.
COPUP

or disconnection of pump
cascade control.
