Yaskawa J1000 small and simple frequency converter

This "plug and use" J1000 model can achieve the adjustable speed of small machinery with simple operation, saving electricity and energy.

After being installed on the machinery, one can immediately feel the outstanding performance of this compact "high-quality" frequency converter.

Features

It is fully functional, with convenient operation and machine protection as its fundamental principles

Compact design

One frequency converter adopts two heavy-load rated specifications that can select the light-load (ND) rating and heavy-load (HD) rating. Parameters can be simply set according to the type of machinery of the customer. If the ND rating is selected, it can be applied to motors with a larger capacity by one grade. It is small in size and can be set side by side to reduce the volume of the control cabinet.

Simple operation

In the parameter setting mode, the basic parameters required for the operation of the inverter can be simply set. The convenience of "being able to use it just by wiring". A verification function (comparison function) that can simply confirm the parameters that have been changed to the factory Settings.

Care for the environment

The standard product complies with the RoHS (European Restriction of the Use of Certain Hazardous Substances) directive.

The Swing PWM mode for suppressing electromagnetic noise can solve the problem of shrill sounds.

Support stable operation

It can start easily even under heavy loads

During the all-domain fully automatic torque boost operation, regardless of acceleration, deceleration or constant speed, high torque is generated, ensuring smooth mechanical start-up.

Achieve 100% torque at low speed 1.5Hz and 150% torque at 3Hz (HD rated).

Complete braking function

Due to the excitation braking function, emergency braking can be achieved even without a braking resistor. Moreover, all models are equipped with built-in braking transistors. As long as the braking resistor is added, a large braking force can be obtained.

Perfect protection function

It is equipped with a standard inrush current suppression circuit, which can prevent inverter failure even if the power supply is unstable.

Convenient functions for debugging and maintenance

Easy to maintain

It can monitor and inspect the maintenance time of capacitors, cooling fans, burst prevention relays and IGBTs. The detachable cooling fan is installed on the upper part of the frequency converter and can be simply exchanged without removing the main circuit wiring.

Suppress the high-order harmonics of the power supply

It can be connected to AC reactors (optional) and DC reactors (optional).

Safe stop during power outage

It is equipped with the KEB(Kinetic Energy Back-up) function, which enables the motor not to run freely during power failure but to decelerate and stop quickly and safely

Convenient optional accessories to use

Frequency setting potentiometer (optional accessory)

A frequency setting potentiometer can be installed. The operating frequency can be adjusted not only through parameters but also with potentiometers, simplifying on-site debugging work.

LED Operator *1 (Optional accessory)

If an LED operator is used, it can be operated within 3 meters of the frequency converter.

If it is set on the panel of the control cabinet, the operation and monitoring of the frequency converter inside the cabinet can be carried out without opening the cabinet door.

DriveWizard Plus*2

If the inverter engineering technology tool DriveWizard Plus is used, the debugging and maintenance of the inverter can be made much simpler by using a computer. It is convenient for parameter management and is also equipped with mode operation, oscilloscope function, etc.

It can be used for RS-422/485 communication (optional accessory)
