C300 Series Inverter

Product description



C300 Series Inverter

Standard Features

  1. Various voltage levels: support single-phase 220V, three-phase 220V, three-phase 380V, three-phase 480V, three-phase 520V, three-phase 690V, three-phase 1140V voltage levels and so on.
  2. Various control modes: support vector control with speed sensor (FVC), vector control without speed sensor (SVC), V/F control mode and V/F separation mode control.
  3. Various field bus: support Modbus-RTU and other communication modes.
  4. Various encoder types: support differential encoder, open collector encoder, rotary transformer encoder, UVW encoder and other encoder types.
  5. New control algorithm of vector control without speed sensor (SVC): it has better low-speed stability and higher low-frequency torque carrying capacity, and supports SVC torque control at the same time.
  6. Support user programming: users can realize secondary development by using the user programming expansion card.
  7. Rich function extension:

A. virtual input/output IO;

B. Motor overheat protection can support PT100 and PT1000 sensors;

C. Fast current limiting can solve frequent over-current faults in inverters;

D. Multi-motor parameter switching;

E. Input and output of AI/AO analog quantity with higher accuracy;

F. Fault handling mode is optional;

G. PID process control parameter switching;

H. PID process control feedback loss detection;

I. PID process control can be used for positive and negative logic selection and response delay setting;

J. Timing operation and PLC operation setup cycle or single operation.
