Solution
Check if there is strong
interference to the external
equipment
1. Check the input power
2. Check if the DEC time of
the load is too short or the
inverter starts during the
rotation of the motor or it
needs to increase the energy
consumption components.
3. Install the braking
components.
4. Check the setting of
relative function codes.
1. Increase the ACC time
2. Check the input power
3. Select the inverter with a
larger power
4. Check if the load is short
circuited (the grounding short
circuited or the wire short
circuited) or the rotation is not
smooth.
5. Check the output
configuration.
6. Check if there is strong
interference.
7. Check the setting of
relative function codes.
1. Check the input power of
the supply line.
2. Check the setting of
relative function codes.
Check the power of the
