Specifications
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 5 frequency sources: digital, analog voltage, analog
current, multi-speed and serial port. They can be switched
through a variety of ways.
Input terminals
6 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); 2 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,
and short circuit to ground protection.
