Built-in simple PLC, multiple speedsIt realizes up to 16 speeds via the simple PLC function or combination of DI terminal states
Built-in PIDIt realizes closed loop control system easily
Auto voltage regulation
It can keep constant outputvoltage automatically when the mains voltage fluctuation.
Overvoltage/Over current
stall control
The current and voltage are limited automatically during the running process so as to avoid frequently tripping due to overvoltage/over current.
Rapid current limit
It can auto limit running current of frequency inverter to avoid frequently tripping
Torque limit and control(Excavator characteristics) It can limit the torque automatically and prevent frequently over current tripping during the running process. Torque control can be implemented in the VC mode
High performanceControl of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology
Instant power off not stopThe load feedback energy compensates the voltage reduction so that the frequency inverter can continue to run for a short time.
Rapid current limitTo avoid frequently over current faults of the frequency inverter.
Virtual I/OFive groups of virtual DI/DO can realize simple logic control.
Timing controlTime range: 0.0~6500.0 minutes
Multi-motor switchoverTwo motors can be switched by two groups of motor parameters.
Multiple communication protocolsIt supports communication bus via Modbus-RTU, PROFIBUS-DP, CANlink and CANopen
Motor overheat protectionThe optional I/O extension card enables AI3 to receive the motor temperature sensor input (PT100, PT1000) so as to realize motor overheat protection
Multiple encoder typesIt supports various encoders such as differential encoder, open-collector encoder, resolver, UVW encoder, and SIN/COS encoder.
Advanced background softwareIt supports the operation of frequency inverter parameters and virtual oscillograph function,by which the state of frequency inverter can be monitored
