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
Limit frequency, jump frequency, frequency compensation, auto-
tuning, PID control
DC current
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.
