Hitachi industrial SJ700B AC Variable Speed Drives outperforms on performance, capabilities and functions of its predecessor, the Hitachi L700. The industrial SJ700B Series inverters come with improved sensorless vector (SLV) control algorithm, which allows SJ700B Series inverters to develop 150% torque at 0.5 Hz, ideal for wide range of applications. Another key upgrade in the SJ700B inverters (SJ700B AC Variable Frequency Drives) is Hitachi’s EzSQ (Easy Sequence) built-in programming function, which provides the functionality of a PLC built into the inverter. Following are some of the key features of Hitachi industrial SJ700B Series AC Variable Speed Drives.
Hitachi SJ700 Series VFDs reasserts its technological leadership with an improved features. The SJ700B 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 SJ700B is given a position command, speed command, and acceleration/deceleration times. The shaft moves from position A to position B following the defined profile and then maintain the shaft in servo lock status.
Hitachi has also greatly simplified the auto-tuning process, making commissioning trouble-free. Enhancement in the SJ700B is Hitachi’s EzSQ (Easy Sequence) built in programming function. It is similar to 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 software provided at no charge.
