Product Introduction 3
E500 Series Universal Low-Power Inverter
Control
Characte-
ristics
Automatic current
limiting and voltage
limiting
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.
Under voltage limiting
during 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.
Typical
functions
Multispeed cont0rol
7-section programmable multispeed control and 5
kinds of running modes available for selection
Optional built-in PID
controller
Internal integrated optimized PID controller, allowing
for simple closed-loop control.
RS485 communication
and linkage control
SUNFAR user-defined protocol or MODBUS
protocol.
Frequency
setting
Analog
input
DC voltage 0-10V, and DC current 0-20mA (optional)
Digital
input
Operating panel setting, potentiometer setting, RS485
port setting, UP/DW terminal control, and multiple
combined setting with analog input.
Output
signal
Relay and
OC output
One channel OC output and One channel relay output
(TA, TC), with up to 16 kinds of optional meanings.
Analog
output
One channel 0-10V voltage signal, and upper and
lower limit can be set.
Automatic voltage
regulation running
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.
Setting of acceleration
and deceleration time
0.1~600.0Sec continues setting, and deceleration and
acceleration curve S type and liner mode are optional.
Timer One built-in timer
Running function
