Built-in Simple PLC / Multiple Speeds:
It realizes up to 16 speeds via the simple PLC function or
combination of DI terminal states.
⚫
Built-in PID:
It realizes closed loop control system easily.
⚫
Auto voltage regulation (AVR):
It can keep constant output voltage automatically when the mains
voltage fluctuation
⚫
Overvoltage/ Overcurrent 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:
To avoid frequently over current faults of the frequency inverter.
⚫
Torque Limit and Control:
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 Performance:
Control of asynchronous motor is implemented through the high-performance current
vector control technology.
⚫
Virtual I/O:
Five groups of virtual DI/DO can realize simple logic control.
⚫
Timing Control:
Time range: 0.0~6500.0 minutes
⚫
Motor Overheat Protection:
The 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 Types:
It supports differential encoder, open-collector encoder
⚫
Protection Mode:
Motor short-circuit detection after power-on, input/output phase loss protection, over
current and overvoltage protection, less voltage protection, overheat protection and overload protection,etc
