conversion attribute selection, timing pump change, etc.
Self-inspection of
peripherals after
power-on
After powering on, peripheral equipment will perform safety
testing, such as ground, short circuit, etc.
Multiple inverters can use a common DC bus
The current limiting algorithm is used to reduce the inverter
overcurrent probability, and improve whole unit antiinterference
capability.
Timing control function;time setting max 6500min
Keyboard/terminal/communication
Analog setting DC 0 to 10V/0 to 20mA including adjustable , panel
potentiometer setting, Communication setting, keyboard setting.
Interrupt controller output
When the protection function is active, you can automatically or
manually reset the fault condition.
Including DC(0 to 10V), DC(0 to 20mA)
Motor status display, stop, ac/deceleration, constant speed,
program running status.
Contact capacity :Normally open contact 5A/AC 250V,1A/DC 30V.
Two-way analog output, 16 signals can be selected such as
frequency, current, voltage and other, output signal range (0 to
10V / 0 to 20mA).
Limit frequency, jump frequency, frequency compensation, auto-
tuning, PID control
Built-in PID regulates braking current to ensure sufficient braking
torque under no overcurrent condition
Overvoltage protection, undervoltage protection, overcurrent
protection, overload protection, overheat protection, overcurrent
stall protection, overvoltage stall protection, losting-phase
protection (Optional), External fault,communication error, PID
feedback signal abnormalities, short circuit to ground protection.
