Torque response
≤ 40ms (vector control W/O PG)
Torque boost
Automatic torque boost; manual torque boost(0.1% to 30.0%)
DC braking
DC braking frequency: 0.0Hz to max. frequency, braking time:
0.0 to 100.0 seconds, braking current value: 0.0% to 100.0%
Jogging control
Jog Frequency Range: 0.00Hz to max. frequency;
Jog Ac/deceleration time: 0.0s to 6500.0s
Multi-speed
operation
Achieve up to 16-speed operation through the control terminal
Built-in PID
Easy to realize closed-loop control system for the process control.
Automatic voltage
regulation(AVR)
Automatically maintain a constant output voltage when the voltage
of electricity grid changes
Torque limit and
control
"Excavator" feature - torque is automatically limited during the
operation to prevent frequent overcurrent trip; the closed-loop
vector mode is used to control torque.
Personalization
function
Self-inspection of
peripherals after
power-on
After powering on, peripheral equipment will perform safety
testing, such as ground, short circuit, etc.
Common DC bus
function
Multiple inverter can use a common DC bus.
Quick current
limiting
The current limiting algorithm is used to reduce the inverter over
current probability, and improve whole unit anti-interference
capability.
Timing control
Timing control function: time setting range(0m to 6500m)
Running
Input signal
Running
method
Keyboard/terminal/communication
Frequency
setting
10 frequency settings available, including adjustable DC(0 to
10V), adjustable DC(0 to 20mA), panel potentiometer, etc.
Start signal
Rotate forward/reverse
Multi-speed
At most 16-speed can be set(run by using the multi-function
terminals or
program
)

control run
Fault reset
When the protection function is active, you can automatically or
manually
reset the fault condition.
