Select inverter with right
capacitance.
Prolong acceleration time
Restart motor until it totally
stops. Set [F1.00] as 1or2.
Reset V/F curve or torque
boost value.
Prolong acceleration time
properly.
Check peripheral equipments
and restart after fault
eliminating.
Seek support from vendor.
Check system wiring, earth,
shield and deal as required.
Meet the environment
requirement.
Clear the air channel.
Check and reconnect the wire
Change the same new fan.
