Basic functions Carrier frequency 2-12 KHz (The device can intelligently and automatically make optimal adjustment according to load characteristics and drive temperature.)
Input voltage unbalance degree Maximum: ±3% of rated inter-phase input voltage
Efficiency About 98% (when operating at rated power)
Maximum frequency 0-500Hz(vector control) 0-1000Hz (V/F control)
Input frequency resolution Digital setting: 1RPM Analog setting: 0.025% of maximum RPM
Control mode Open-loop V/F control Open-loop vector control (SVC)/close-loop vector control (FOC)
Startup torque 200% @ 0.25Hz@ Open Loop(open-loop control) 200% @0Hz@ Close Loop(close-loop control)
Speed range 1:200 @ Open Loop(open-loop control) 1:3000 @ Close Loop(close-loop control)
Steady-speed precision ±0.5% @ Open Loop(open-loop control) ±0.01% @ Close Loop(close-loop control)
Overload capacity Heavy load application: 60s at 150% rated current @40°C. The time depends on the drive temperature under other conditions. Light load application:60s at 110% rated current @40°C. The time depends on the drive temperature under other conditions.
Enhancements Torque boost Automatic torque boost. Manual torque boost 0.1%-30%
V/F curve Intelligent adaptive
V/F separation Two methods: full separation, half separation
Acceleration and deceleration curves straight-line or S-curve acceleration and deceleration method Two acceleration time values. The acceleration and deceleration time range:0.0s-650.00s
Simple PLC function Achieve operation of up-to-16-stages speed(via built-in PLC or control terminals)
Built-in PID Conveniently achieve the process control close-loop control system
Automatic voltage regulation (AVR) When the grid voltage changes, the device automatically maintains constant output voltage.
Over-voltage and over-current stall control The current and voltage are automatically limited during running to avoid jump faults due to frequent over-current and over-voltage
Fast current limiting Over-current faults are minimized to guarantee normal operation of the frequency converter.

Torque limiting and control The torque is automatically limited operating (to avoid frequent over-current jumping fault due to too large torque).
Protection function Output short-circuit protection, input & output phase loss protection, over-current protection, Over-voltage protection,under-voltage protection, overheat protection, overload protection, brake chopper overload protection, brake chopper short-circuit protection, brake resistor overload protection
Non-stop during transient interruption Keep the frequency converter operating in a short time (by reducing feedback energy compensation voltage at the moment of power outage). The duration depends on the mechanical inertia of the load at that time.
Timing control Timing control function. The time range and precision is 0.0-6500.0(min).
Switching multiple motors Support switching among four groups of motor parameters.
Bus communication The standard configuration uses the built-in Modbus/CANopen communication, which can be extended to Profibus-DP bus communication.
