The time depends on the drivetemperature under other conditions.
Torque boost
Automatic torque boost. Manual torque boost 0.1%-30%
Acceleration and deceleration curves
Straight-line or S-curve acceleration and deceleration mode, 
The acceleration and deceleration time range : 0.0s-650.00s
Simple PLC function
Achieve operationof up-to-16-stages speed(via built-in PLC or control terminals)
Built-in PID
Supported base on certain order amounts
AVR function
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.
