LED display Description Possible causes Corrective action
SE08
PM Motor mode error
Inverter rating does not support
the PM Motor mode.
• Inverter rating does not support PM motor
control mode.
• Check control mode.
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
braking
PID feedback signal falls below
level specified in 10-12 (PID feed-
back 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 - 03-08 = 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.
STP0
Zero Speed Stop Error
Frequency command is smaller
than 01-08 without DC brake.
• Frequency command is smaller than motor
minimum output frequency.
• Adjust frequency command
STP1
Direct Start
warning
The inverter can’t start directly
due to 07-04=1
• Run command from the terminal is enabled
and 07-04=1.
• Remove the run command from the terminal
first, and enabled later
STP2
External Terminal
Stop Error
External Terminal is main run
command source selection
(00-02=1) and run command
executes but executes stop
command from keypad.
• Run command executes from external termi-
nal but executes stop command from keypad.
• Remove the run command from external
terminal
EnC
Encoder Error
PG card is connected but encoder
signal error is detected when
motor auto rotational tuning is
running.
• Abnormal encoder signal
• Check encoder wiring
• 17-07 PG pulse number setting is not corre-
sponding to the encoder.
• Replace the encoder.
RunEr
Wrong running direc-
tion Error
Running direction is different from
11-00
• Check the command among 11-00, jog and DI
control to see if any difference.
• Revise the command among 11-00, jog and
DI control to see if any difference
PArEr
Parameter
setting error
Parameter setting error • The parameter setting is wrong • Please refer to the manual for correct setting
