The SJ300-EL series variable frequency drive is
specialized for the special requirements of elevator
control.
Various functions such as vector control with a pulse
generator, sigmoid acceleration/deceleration for each
speed step, torque bias, etc. enable the SJ300-EL to solve
demanding applications.
Sigmoid Curve for Elevator Control,
Acceleration and Deceleration Time
Settings for Multispeed
SJ300-EL features fully tunable Sigmoid ("S" letter)
acceleration and deceleration function. Acceleration and
deceleration start/end ratio and time are settable
independently for each multispeed step.

Variable ASR* gain setting function is available. Stable operation is
obtained with high-gain setting at stopping or slow speed, low-gain at
high-speed steady run.
Settable up to eight points.

Battery-backup for Power Failure (customized specification)
In case of power failure, the SJ300-EL can continue operation with battery or UPS.
Please provide specifications of battery or UPS to Hitachi for review.
Emergency Control
In case of a malfunction of pulse generator, the SJ300-EL automatically changes control
method from vector control to SLV or V/f and continues operation.
