Product Description

OEM 11KW 3 Phase Variable Frequency Drive 50.00Hz Jog Frequency

Three Phase VFD 0.00Hz To 50.00Hz Jog Frequency Automatic Torque Boost


The CM540 series is a high torque type vector inverter. Its motor control performance increases obviously. The inverter can implement the control of asynchronous motor and permanent magnet synchronous motor (PMSM), supports multi-kind PG and IO cards(including CAN COMMUNICATION).The function is more powerful. It is used to drive various automation production equipment involving textile, paper-making, machine tool, packing, food, elevator, crane, pertrolum machinery, fan, pump etc.

Simple PLC, multistage speed operation It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.
Built-in PID It can keep constant output voltage automatically when the mains voltage changes.
Automatic voltage regulation(AVR) Automatically maintain a constant output voltage when grid voltage changes.
Over voltage/Over current loss of speed control Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage
Rapid current limit Minimizing over-current fault and protect the normal operation of converter.
Torque limit and control "Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.


Frequency Inverter Daily Maintenance:

1.Daily Maintenance

Many factors such as ambient temperature, humidity, dust, vibration will cause the internal components aging and give rise to the occurrence of potential faults or lessen the service life of the VFD. Therefore, it is necessary to conduct routine maintenance to the VFD.


2.Daily inspection items:

a) When running, whether the motor has abnormal sound.

b) When running ,whether the motor generates vibration.

c) Whether the installation environment of the VFD changes.

d) Whether the cooling fan of the drive is working properly.

e) Whether the VFD is overheating


3.Daily cleaning:

a)Reserve the drive in a clean state.

b)Effectively remove the dust on the surface of the inverter to prevent dust entering the inside of the inverter, especially the metal dust.

c) Effectively clear the oil from the cooling fan.


4.Routine Checking

Check regularly the place which is difficult to check when the drive is running, routine checking items:

a) Check the air duct, and regularly clean.

b) Check whether the screws are loose.

c) Check whether the drive is corroded.

d) Check whether the terminals have arc traces.

e) Check whether the main circuit is insulation.

Notes: When using a DC 500V Mega-Ohm-Meter to test insulating resistance, please make sure the main circuit and the frequency inverter is disconnected. please don't use the insulation resistance meter to test the insulation of the control circuit. High voltage test is unnecessary(it has already been conducted before delivery).


5.Replacing of Quick-wearing Parts

The quick-wearing parts of the frequency inverter mainly includes cooling fan and electrolytic capacitors for filters. Their lifetime depends largely on their application environment and maintenance condition. Normally, lifetime is:

Components Life
Fan 2~3 years
Electrolyte capacitor 4~5 years
