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.

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.

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).

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.
