SJ700 Series Information

  • General Purpose Drive
  • Open Loop Vector
  • 0.50 to 75 HP
  • 230 VAC 3PH, 460 VAC 3PH
  • NEMA 1, IP20 Enlosure
Hitachi SJ700 Series VFDs reasserts its technological leadership with an improved sensor‑less vector (SLV) control algorithm that enables the SJ700 to develop more than 200% starting torque at 0.3 Hz. The SJ700 can develop 150% torque at 0 Hz, ideal for vertical lift applications, using Hitachi's unique "0 Hz Domain" open‑loop control mode.

Hitachi has also greatly simplified the auto‑tuning process, making commissioning trouble‑free. Enhancement in the SJ700 is Hitachi's EzSQ (Easy Sequence) built in programming function. It's like having a PLC built into the inverter! In many cases, the need for a separate PLC can be eliminated. The program is developed on a PC and then downloaded to the inverter using the simple to use EzSQ software provided at no charge.

The SJ700 also incorporates true servo‑like position control, offering a low‑cost motion control solution. Mated with a general‑purpose induction motor with an encoder, the SJ700 is given a position command, speed command, and acceleration/deceleration times. The shaft will move from position A to position B following the defined profile and then maintain the shaft in servo lock status.

  • Compact Size
  • High Function
  • Global Standards
  • Easy Maintenance
  • Adaptive Auto‑Tuning
