Features

Hitachi S1 drive is perceived as the new standard for general purpose inverter, highly flexible and user friendly for easy commissioning. It is suitable for a wide range of applications, using advanced sensorless vector control. S1 achieves exceptional stability and efficient drive characteristics to save energy and maximize performance.

  • Supports SVC control
  • Enables high precision of speed torque control and fast speed response
  • Integrates safety function-STO (Safe Torque OFF, SIL2)
  • The unique I/F control is very suitable at low speed with high torque requirements
  • The transition from rotating state to dc braking is very smooth. The current impact is small, and the current response of dc braking is faster.
  • Excellent performance at “Catch-on-the-Fly”
  • Solid plastic housing 4 – 75kW
  • Solid metal housing 90 – 500kW
  • ≤37kW Standard built-in DBU
  • Internal C3 EMC filter, Optional external C2 EMC filter
  • PID control function (with sleep function).
  • Automatic voltage regulation (AVR), Torque compensate function
  • Optional parameter copy LED external keypad, meeting the requirements of diverse applications
