[. . . ] VARIABLE FREQUENCY DRIVE for ELEVATOR CONTROL 3phase 200V class: 0. 4(1/2) - 55(75) kW(HP) 3phase 400V class: 0. 75(1) - 150(200) kW(HP) The SJ300-EL series variable frequency drive is specialized for the special requirements of elevator control. [. . . ] A motor with a pulse generator is required for vector control. SJ300 (Unit with application-specific software) Hitachi Industrial Equipment Systems Co. , Ltd. Gain Adjustment *ASR: Automatic Speed Regulator ASR gain [%] 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. 100% f1 f2 f3 f4 f5 f6 f7 f8 Output frequency Torque Bias Function Load cell The SJ300-EL controls starting torque with feedback signal from the load cell. For smoother elevator move! SJ300-EL IM PG Counter weight Cargo Flexible Brake Control Signal Setting Flexible adjustment is available for brake control. Braking frequency and release frequency are independently settable.
