TECO L510S Series - 5.1.3 Special conditions

5-5
5.1.3 Special conditions
Display Fault Description
StP0
Zero speed at stop
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
Fail to start directly
On power up.
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
Keypad Stop
Operated when
inverter in external
Control mode.
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.
External
Rapid stop
When external rapid stop input is activated the inverter will
decelerate to stop and the display will flash with E.S. message.
b.b.
External base block
When external base block input is activated the inverter stops
immediately and then the display will flash with b.b. message.
PdEr
PID feedback loss PID feedback loss is detected.
Alter
auto tuning error other errors show up in the process of auto tuning.
OH3
motor over heat
warning
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.
LOPB
Low pressure error
 The feedback signal is not connected.
 Due to feedback value of pump pressure is lower than limit of
minimum flow.
HIPB
High pressure error
Due to feedback value of pump pressure is lower than limit of
maximum flow.
COPUP
Breaking error of
multiple pumps
communication
Communication breaking or disconnection of pump cascade
control.
