Detailed introduction

Frequency converter

Elevator inverter is a kind of special equipment used for elevator control. Elevator special inverter is the high-end products in small and medium power inverter, which makes the elevator efficiency, stable operation, long service life, combined with PLC or microcomputer control, more show the superiority of non-contact control: simplified circuit, flexible control, reliable operation, convenient maintenance and fault monitoring.

Frequency converter is a kind of common equipment in modern electrical equipment,

Elevator frequency converter is a kind of instrument which is specially used for elevator control. Elevator Inverter for elevator control is S, that is to start and stop the acceleration are relatively moderate, but the middle process, acceleration is faster, mainly to ride comfort, energy saving is on the one hand, this is a bit of general inverter.

Control methods include:

Speed control mode: frequency converter to control the output frequency to control the motor speed, the output torque of the motor is determined by the load side, but will be limited to the maximum output torque, applicable to all types of speed control purposes;

Torque control mode: inverter to control the inverter output torque as the goal, the motor speed by the load side of the decision, but will be limited to the set range. In this way, the user can set the tension value, and then through the frequency converter with the coil diameter calculation function, to achieve tension open loop control.
