Hitachi SJ700 Serie
Hitachi SJ700 series AC Motor Speed Controllers, specially developed by Hitachi, also perform real vector control in open loop. The enhanced feedback-free vector (ASLV) control feature is a patented design. 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.
