HIC-L Series Elevator Servo Drive

The HIC-L series elevator integrates the STO (safety torque off) function to prevent accidental rotation of the motor and meets the safety requirements of the European SIL2 (EN618005-2). This feature eliminates the need for external components, you can use the terminal to achieve security features.

Perfect Motor Driving Technology

• Induction Motor (IM) and Permanent Magnetic Synchronous Motor (PMSM) could be driven with high performance vector control including both speed sensor control and speed sensor-less control.

• Easy motor type control switch function

• Power Range could meet most kinds of elevators application.

Multiple Control Mode and Encoder Interfaces

• V/F Control, speed sensor-less Vector Control, speed sensor Vector Control, and special PMSM Vector Control with speed sensor Vector Control.

• Compatible Encoder Interface: Sin/Cos, EnDat, ABZUVW 5V Incremental, Push-pull/Collector/Differential Output Incremental

Abundant Self-study Function

• Multiple self-study functions could fully embody inverter driving performance

• Dynamic and static self-study functions for IM and PMSM.
