Inverters Target Elevators

June 3, 2004
The SJ300-EL Series of inverters are specialized for elevator controls. They feature fully tunable Sigmoid acceleration and deceleration.

INVERTERS TARGET ELEVATORS

Acceleration and deceleration start/end ratio and time are set independently for each multispeed step. Variable ASR (Automatic Speed Regulator) gain setting enables stable operation with high-gain at stopping or slow speed, and low-gain at high-speed steady run. Up to eight points can be set. A feedback signal from a load cell controls starting torque for smoother operation. Braking frequency and release frequency are set independently. In case the pulse generator malfunctions, the SJ300-EL changes its control method from vector to SLV or V/Hz and continues operation.
