function
Quick current
limiting
The current limiting algorithm is used to reduce the inverter over
current probability, and improve whole unit anti-interference
capability.

Analog output
Two-way analog output, 16 signals can be selected such as
frequency,
current
, voltage and other, output signal range (0 to 10V
/ 0 to 20mA).
Output signal
At most 4-way output, there are 40 signals each way
Run function

braking
Built-in PID regulates braking current to ensure sufficient braking
torque under no overcurrent condition.
Running command
channel
Three channels: operation panel, control terminals and serial
communication port. They can be switched through a variety of
ways.
Frequency source
Total 10 frequency sources: digital, analog voltage, analog current,
multi-speed and serial port. They can be switched through a variety
of ways.
Input terminals
8 digital input terminals, compatible with active PNP or NPN input
mode, one of them can be for high-speed pulse input (0 to 100 kHz
square wave); 3 analog input terminals for voltage or current input.
Output terminals
2 digital output terminals, one of them can be for high-speed pulse
output(0 to 100kHz square wave); one relay output terminal; 2
analog output terminals respectively for optional range (0 to 20mA
or 0 to 10V), they can be used to set frequency, output frequency,
speed and other physical parameters.
Protection function
Inverter protection
Overvoltage protection, undervoltage protection, overcurrent
protection, overload protection, overheat protection, overcurrent
stall protection, overvoltage stall protection, losting-phase
protection (optional), communication error, PID feedback signal
abnormalities, PG failure and short circuit to ground protection.
