Protection/alarm function
Automatically detect motor’s stator current and voltage and control
it within allowable range according to special algorithm, regardless
of any running process like acceleration, deceleration or static
running.
Especially for users of low-grid voltage and frequently fluctuating
grid voltage. Even within the voltage range lower than allowable
value, the system can maintain longest running time according to
special algorithm and residual capacity distribution strategy.
7-section programmable multispeed control and 5 kinds of running
modes available for selection
Internal integrated optimized PID controller, allowing for simple
closed-loop control.
SUNFAR user-defined protocol or MODBUS protocol.
DC voltage 0-10V, and DC current 0-20mA (optional)
Operating panel setting, potentiometer setting, RS485 port setting,
UP/DW terminal control, and multiple combined setting with
analog input.
One channel OC output and One channel relay output (TA, TC),
with up to 16 kinds of optional meanings.
One channel 0-10V voltage signal, and upper and lower limit can
be set.
Three kinds of voltage regulation modes including dynamic, static
and none are available for selection according to different
requirements, so as to achieve most stable running effect.
0.1～600.0Sec continues setting, and deceleration and acceleration
curve S type and liner mode are optional.
One built-in timer
Setting of upper and lower limiting frequency, REV running
limiting, RS485 communication, and control of progress increase
and decrease of frequency, etc.
Output frequency, output current, output voltage, motor revolution,
set frequency, module temperature, analog input and output and
so on.
The nearest 4 times of fault records, five items of running
parameter records at the time of latest fault trip including, the
output frequency, output current, output voltage, DC voltage and
modular temperature.
Over current, overvoltage, under voltage, overheat, short circuit,
internal memory fault, etc
