Sequence Operation Description
6 Rotate the potentiometer counterclockwise (leftwards) The motor decelerates
7 Press Stop key Enter the command for stopping. The motor stops.

The default control mode of the frequency converter is operating
panel control.
6.3 Restore Parameters to Factory Defaults
If the frequency converter fails to run the motor due to incorrect parameters,
a simple solution is to initialize the parameters to factory defaults. Set
[b0.02]=1 will start initialization to restore factory defaults.
Please be sure that the parameters after factory defaults restore match with
the motor and the field application. Adjust the parameters after factory de‐
faults restore if necessary.

6.4 Solutions for Simple Fault during Commissioning
1. Over current occurs during acceleration (O.C.-2): Increase the accelera‐
tion time.
2. Over voltage occurs during deceleration (O.E.-3): Increase the decelera‐
tion time.
3. Over current occurs immediately after pressing the Run key (O.C.-2): In‐
correct wiring. Check if U, V, W outputs of the main circuit are shorted or
grounded.
4. The motor runs in the direction opposite to the desired one: Change the
sequence of any two phases of U, V and W.
5. The motor vibrates and runs in uncertain directions after each starting:
One phase of U, V and W is disconnected (output phase loss).
6.5 Notes on Frequent Start and Stop
1. Do not use the electromagnetic contactor KM connected prior to termi‐
nals L1, L2 and L3 to start or stop the frequency converter to avoid early
aging and damage of the filter capacitor. External terminals FWD, REV
and X1 - X8 may be used to start and stop the frequency converter.
2. The current limiting resistor for capacitor recharging may be damaged
due to frequent start and stop with the electromagnetic contactor KM
connected prior terminals L1, L2 and L3.
