10-11
LED display Description Cause Possible solutions
SE03
V/f curve error
V/f curve setting error.
 V/F curve setting error.
01-02 > 01-12 > 01-06
(Fmax) (Fbase) (Fmid1)
>01-08;
(Fmin)
 Check V/F parameters
SE05
PID selection
error
PID selection error.
 10-00 and 10-01are set to 1
(AI1) or 2 (AI2)
simultaneously.
 When 23-05=0 and 10-33>=
1000 or 10-34≠1.
 Check the setting value of
parameters 10-00 and
10-01.
 Check the setting value of
10-33, 10-34 and 23-05.
HPErr
Model selection
error
Inverter capacity setting error:
Inverter capacity setting 13-00
does not match the rated
voltage.
 Inverter capacity setting
does not match voltage
class (13-00).
 Check inverter capacity
setting 13-00.
SE09
PI setting error
Inverter PI setting error
 Inverter pulse input
selection (03-30) selection
conflicts with PID source
(10-00 and 10-01).
 Check pulse input
selection (03-30) and PID
source (10-00 and 10-01).
FB
(flash)
PID feedback
breaking
PID feedback signal falls
below level specified in 10-12
(PID feedback loss detection
level) for the time specified in
10-13 (Feedback loss
detection time). Active when
parameter (10-11 = 1).
 Feedback signal wire
broken
 Feedback sensor broken.
 Check feedback wiring
 Replace feedback sensor.
USP
(flash)
Unattended
Start Protection
Unattended Start Protection
(USP) is enabled (enabled at
power-up.)
 USP at power-up (activated
by multi-function digital
input) is enabled. The
inverter will not accept a
run command.
 While the warning is active
the inverter does not
accept a run command.
(See parameter 03-00 -
03-05 = 50).
 Remove run command or
reset inverter via
multi-function digital input
(03-00 to 03-07 = 17) or
use the RESET key on the
keypad to reset inverter.
 Activate USP input and
re-apply the power.
LFPB
Low flow error
Low flow error
 The feedback signal is not
connected.
 Due to HVAC feedback
value is lower than limit of
minimum flow.
 Check feedback signal is
correct and with right
connection.
 Check if feedback value is
lower than limit of
minimum flow.
HFPB
High flow error
High flow error
 Due to HVAC feedback
value is lower than limit of
maximum flow.
 Check feedback signal is
correct.
 Check if feedback value is
lower than limit of
maximum flow.
