Item Item Description
When the network voltage changes,it canregulate
PWM output automatically to maintain constant
voltage.
Auto voltage
regulation(AVR)
This can form a convenient closed-loopcontrol
system(CLCS),and is applicable to pressure control,
flow control and other process control.
Built-in PID
Control function
operator panel control,external terminal control
and COM control
Operating command
Panel potentiometer setting,operator panel
setting,external terminal up/down setting,analog
voltage signal or external potentiometer setting,
analog current signal setting,analog assembly
setting,485 COM setting and etc.
DC braking
Forward/Reverse signal,multiple speed signal,
failure signal,reset signal and etc.
Input Signal
Programmable relay,open-collector output,failure
signal output and etc.
Output signal
This can realize the output offrequency,current and
other physical quantity by outputting 0 10V or
0 20mA DC signal and0 10KHz digital signal.
Multi-function
analog and digital
ouput terminal
Operating function
With an external braking resistor,the maximum
braking torque may reach 100%.
Dynamic braking
This can be selected when themotor starts or stops
with the action frequency of 0 20Hz,action current
level of 0 100% and actuation time of 0 30 sec.,
which can be set in sequence.
