YASKAWA J1000 Compact Simple Inverter Features

Full-featured, with ease of operation and machine protection as fundamentals

• Compact design

  One inverter adopts dual load rating specifications allowing selection of light load (ND) rating and heavy load (HD) rating. Parameters can be easily set according to the customer's machine type. If ND rating is selected, it can be applied to a motor one size larger in capacity. It is small in size and can be installed side by side, reducing control panel volume.

• Simple operation

  In parameter setting mode, the basic parameters required for inverter operation can be easily set. Convenience of "just wire and use." A verification function (comparison function) that allows easy confirmation of parameters that have been changed from factory settings.

• Environmentally friendly

  Standard products comply with the RoHS (Restriction of Hazardous Substances) Directive.

  Adopts Swing PWM method that suppresses electromagnetic noise, solving the problem of harsh noise.

  Noise comparison between conventional method and Swing PWM method

Supports stable operation

• Easy starting even under heavy load

  During full-range, fully automatic torque boost operation, high torque is generated during both acceleration/deceleration and constant speed, and the machine starts smoothly.

  Achieves 100% torque at low speed 1.5 Hz, 150% torque at 3 Hz (HD rating).

• Complete braking functions

  Thanks to the over-excitation braking function, emergency braking is possible even without a braking resistor. Furthermore, all models have a built-in braking transistor, and simply adding a braking resistor provides a large braking force.

  Deceleration time range of over-excitation braking function

• Comprehensive protection functions

  Standard built-in inrush current suppression circuit prevents inverter failure even if the power supply is unstable.

Functions for easy commissioning and maintenance

• Easy maintenance

  Can monitor and check maintenance time for capacitors, cooling fans, inrush prevention relays, and IGBTs. The detachable cooling fan is mounted on the top of the inverter, allowing easy replacement without removing main circuit wiring.

• Suppresses power supply harmonics

  Can connect AC reactor (optional) and DC reactor (optional).

• Safe stop during power failure

  Equipped with KEB (Kinetic Energy Back-up) function that prevents the motor from free-running during a power failure and enables quick and safe deceleration stop.

Convenient optional accessories

Frequency setting potentiometer (optional)

A frequency setting potentiometer can be installed. The operating frequency can be adjusted not only via parameters but also with a potentiometer, simplifying on-site adjustment work.

LED operator*1 (optional)

If the LED operator is used, operation is possible within 3 m of the inverter.

If installed on the control panel door, the inverter inside the panel can be operated and monitored without opening the door.

DriveWizard Plus*2

If the inverter engineering tool DriveWizard Plus is used, inverter commissioning and maintenance work can be made even easier using a computer. It facilitates parameter management and also includes pattern operation, oscilloscope functions, etc.

Can be used for RS-422/485 communication (optional)

Compatible with MEMOBUS/Modbus protocol.

Can be used by using an interface unit (optional).

Complies with international standards

Compatible with MEMOBUS/Modbus protocol.

Complies with CE, UL, cUL, and other international standards, can be used with confidence worldwide.
