Basic functions

Multiple segment speed running Running via the built-in PLC or control terminal
Built-in PID It is easy to realize process-controller closed loop control system
Auto voltage regulation It can keep constant output voltage automatically in the case of change of network voltage
Over-voltage/current stall control It can limit the running voltage/current automatically and prevent frequent over-voltage/current tripping during the running process
Quick current limit Minimize the over-current fault, protect normal operation of the AC drive
Torque limit&control “Excavators”characteristics, automatically limit torque during operation, prevent frequent over-current tripping. Closed loop vector mode can realize the torque control.

Personalized

function

Instantaneous

Stop non-stop

When instantaneous power off, voltage reduction is compensated through load feedback energy, which could make AC drive keep running in a short period of time.
Rapid current limit To avoid AC drive frequent over-current fault

Daily maintenance


Due to the influences of temperature, humidity and dust in the environment and the effect of vibration, the internal components of frequency converter are resulted to aging, which causes the potential occurrence of the failure for frequency converter or the decrease of the service life for frequency converter. Therefore, it is necessary to implement the daily and regular maintenance to the frequency converter.
Daily inspection items:
1) Whether the sound changes abnormally when the motor is running
2) Whether vibration occurs when the motor is running
3) Whether the installation environment for frequency converter changes
4) Whether the cooling fan of frequency converter functions normally
5) Whether the frequency converter is overheated
6) Daily cleaning:
7) Always keep the frequency converter in clean state.
8) Effectively remove the dust on the surface of frequency converter, thus preventing the dust enter into the inside of the frequency converter. Especially for the metal dust
9) Effectively eliminate the oil in the cooling fan of frequency converter.
Daily maintenance
Please make regular inspections to the places which are hard to be inspected during running.
Regular inspection items:
1) Inspect the air channel and clean it regularly
2) Inspect whether the screw is loose
3) Inspect whether the frequency converter suffers from corrosion
4) Inspect whether the terminal block has the arc traces
5) Insulation test for major loop
Remind: when using the megameter (use DC 500V megameter please) to measure the insulation resistance, the major loop line needs to be disconnected with the frequency converter. Do not use the insulation resistance meter to measure the insulation of the control loop. No need to conduct the high voltage test (it is already completed in delivery).
