Hitachi SJ-700D Serie
Hitachi SJ700D series AC Motor Speed Control Units developed by Hitachi also perform real vector control in open loop. Thanks to this feature, it produces Full Torque at 0.3 Hz in open loop (without the need for an encoder, etc.). Thanks to this high torque and sensitive process control feature it produces, it offers ideal solutions even in the most difficult applications. This product, which also works as a closed loop when desired, can be easily adapted to any system with its user-friendly software.
With Dual Rate feature; CT and VT can be adapted to load operating conditions. Thus, space and cost savings are achieved.
With a single frequency converter, Induction motor (IM) or Permanent motors (PM) can be started.
