6개의 제어 모드를 탑재한 차세대 글로벌 인버터

• 

  Auto tuning

  Its auto tuning function makes the task-free on roublesome motor constants setting. It can make the best tuning even to the other supplier's existing motors.

• 

  High efficiency operation

  During the light load operation, the motor automatically lowers the output voltage and suppressesthe no-load loss of motor. In so doing, it improves the overall energy efficiency.

• 

  Operating ratio setting

  It is a computing function on the gain and bias against against the frequency setting value. It is applied when multiple motors are operated with a different speed in the production line.

• 

  Frequency jump

  It can operate the motor avoiding the mechanical resonance point of the motor at the specified frequency. It is effective during the V/f control.

• 

  Drooping setting

  The load can be balanced when multiple motors that are mechanically linked are operated. It becomes effective in the vector control and PM motor control modes.

• 

  Program frequency setting

  Several types of frequency setting can be fixed, and it is a useful function when there is no need to make the setting value linear. It can be operated by switching the frequency setting of the sequence externally in case the necessary steps of the operation frequencies are set in advance.

• 

  Multi-pump operation

  Multiple pumps can be operated in parallel with one inverter.

• 

  PID control

  A feedback loop of the analog inputs can be configured as feedback.

• 

  Pattern operation

  It is operated by automatically switching the frequency, the driving direction, and the time.

• 

  Traverse operation

  Patterns suited to winding threads uniformly in a spinning system are operated optimally.

• 

  Simple ASR function

  Simple speed control can be performed by installing the speed detection option even when the V/f control mode is selected. High accuracy speed control is possible with simple adjustment.

• 

  Spinning frame operation

  Pattern operation for spinning is performed. Unlike pattern operation, the acceleration and deceleration to the next setting are started right after the setting frequency is achieved. The pattern operation can be restarted from the frequency and the time at stopping after the power recovery when there is a power failure.

• 

  S-shaped cushion

  Speed changes can be made smooth to alleviate the sharp impact at acceleration and stopping.

• 

  Instantaneous restarting

  Even the inverter operation stops during the power outage, its instantaneous stopping and restarting function can search the free-runninng motor rotation frequency after power recovery and match the output frequency and the voltage. In so doing, it can automatically restart the operation.

• 

  Dynamic braking

  During the deceleration, the motor operates as a generator when operated from the load side and electric energy is generated. Braking force is made available by dissipating the energy as heat in resistor.

• 

  DC braking

  By applying the DC power to the motor to produce the energy, braking force can be obtained by dissipating the produced energy as heat.
