AVR function
Yes
Fast current limiting
Overcurrent faults are minimized to guarantee normal operation of the frequency converter.
Timing control
Timing control function. The time range and precision is 0.0-6500.0(min).
Intelligent temperature control
Full cover system temperature testing, intelligent real-time IGBT chip temperature monitoring, and intelligent and optimized adjustment of the carrier and current based on drive temperature changes
Input terminal
The followings are included in standard configuration : 
6 digital input terminals, where DI6 supports the maximum of 50 kHz high-speed pulse input. 2 analog input terminals (where, at least 2 supports 0-10V voltage input or 0-20 mA current input).

The followings are extended as cards : 
5 digital input terminals 2 analog  input terminals, supporting input of -10V to+10V voltage
Output terminal
The followings are included in standard configuration: 
1 high-speed pulse output terminal (supporting 0-50 kHZ square signaloutput);
1 (F0) digital output terminals;
1 (F0) relay output terminals Output terminal (output);
1 (F0) analog output terminals (supporting 0-10V voltage output or 0- 20mA voltage output) ;

The followings are extended as cards: 
3 digital output terminals;
3 relay output terminals;
3 analog output terminals (supporting 0-10V voltage output or 0-20mA voltage output)
Protection function
Output shortcircuit protection, input & output phase loss protection, overcurrent protection,overvoltage protection,undervoltage protection, overheat protection, overload protection, brake chopper overload protection, brake chopper shortcircuit protection, brake resistor overload protection
Non-stop during transient interruption
Keep the frequency converteroperating in a short time (by reducing feedback energy compensation voltageat the moment of power outage). The duration depends on the mechanical inertia of the load at that time.
