Description
Operated when
inverter in external
Control mode.
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.
5.2 General troubleshooting
Status
Checking point
Remedy
Motor runs in
wrong
direction
Is the wiring for the output
terminals correct?
Wiring must match U, V, and W terminals of the
motor.
Is the wiring for forward and
reverse signals correct?
Check for correct wiring.
The motor
speed can
not be
regulated.
Is the wiring for the analog
frequency inputs correct?
Check for correct wiring.
Is the setting of operation mode
correct?
Check the Frequency Source set in parameters
00-05/00-06.
Is the load too excessive?
Reduce the load.
Motor
running
speed too
high or too
low
Check the motor specifications
(poles, voltage…) correct?
Confirm the motor specifications.
Is the gear ratio correct?
Confirm the gear ratio.
Is the setting of the highest output
frequency correct?
Confirm the highest output frequency
Motor speed
varies
unusually
Is the load too excessive?
Reduce the load.
Does the load vary excessively?
1.Minimize the variation of the load.
2.Consider increasing the capacities of the
inverter and the motor.
Is the input power unstable or is
there a phase loss ?
1.Consider adding an AC reactor at the power
input side if using single-phase power.
2.Check wiring if using three-phase power
Motor can
not run
Is the power connected to the
correct L1, L2, and L3 terminals?
is the charging indicator lit ?
1.Is the power applied?
2.Turn the power OFF and then ON again.
3.Make sure the power voltage is correct.
4.Make sure screws are secured firmly.
Is there voltage across the output
terminals T1, T2, and T3?
Turn the power OFF and then ON again.
