TARRYTOWN, NY (September 30, 2013) – Hitachi America, Ltd., Industrial Components and Equipment Division, today announced the introduction of the SJ700B Series of Industrial AC Variable Frequency Drives, with full availability in late October. The SJ700B significantly expands on the performance, capabilities and functions of its predecessor, the L700.
To reassert its technological leadership and ensure unmatched performance, Hitachi has broadened the applicability of this new series by incorporating and upgrading many of the original flagship SJ700 features, such as the industry-leading Sensorless Vector (SLV) control algorithm. This algorithm enables the SJ700B to develop 120% of full torque capabilities at 0 Hz in Hitachi’s exclusive “0 Hz Domain” sensorless vector control mode, as well as 150% torque at 0.5 Hz in sensorless vector operation mode in most models, which is ideal for a wide range of applications beyond just fans and pumps. Additionally, operation in the closed-loop full vector control mode is now possible as well through an optional board. The SJ700B also has a number of built-in features that make the commissioning process quick and the operation of the control trouble-free.
Another notable upgrade in the SJ700B is the higher operating temperature range of -10°C to 45°C. The SJ700B is loaded with additional application integration features such as Hitachi's EzSQ (Easy Sequence) built-in programming function, which provides the functionality of a PLC built into the inverter. Due to this internal capability, in many cases, the need for a separate PLC can be eliminated or the I/O reduced. Programs for various applications such as irrigation pump control or repeatable motion profiles can be developed on a PC and then downloaded to the inverter with the easy-to-use EzSQ software provided at no charge.
The other new helpful features Hitachi has added to the SJ700B include the patented micro-surge voltage suppression to protect the motor winding insulation, advanced trip avoidance functions, configurable sink/source logic on digital inputs, PID, built-in dynamic braking circuit in models up to 40 HP (30 kW,) and built-in EMC filters in all models.
The SJ700B also incorporates features customers have come to expect from Hitachi Variable Frequency Drives. Some of the anticipated features include built-in RS485 Modbus/RTU communication. The SJ700B can be configured via the front-mounted keypad or using Hitachi's ProDriveNext PC-based software.
A truly globally accepted product, the SJ700B is CE, UL, c-Tick-certified and RoHS-compliant.
