Swing Frequency
Function Suitable for some textile and chemical fiber machines by
programmable controlling of the triangular frequency references.
AVR Function
Automatic Voltage Regulation (AVR), automatically keep the
output voltage constant when power supply is not stable.
Stall Prevention
Stall Prevention automatically control the decelerating procedure
by monitoring the bus voltage and prevent overvoltage fault caused
by high inertia or rapid deceleration.
Communication
Function
RS485 communication with standard modbus protocol.
Automatic Energy
Saving Control Automatic decrease output voltage while in the situation of light
load, to achieve efficient energy saving.
Fault Protection
Function Over- current , over voltage, under- voltage, over temperature, lack
of phase, etc.
Personalized function
LED Display
16 parameters can by displayed including running frequency, DC
bus voltage, output voltage, output current, etc.
Password Setting
Four-digit non-zero password can be set and become effective after
exit the password programming mode and wait 1 minute.
Parameter Lock
Function This function can be used to lock the parameter when running or
stop in order to avoid wrong operation.
