Product feafures

"A key shuttle "high-precision rotary encoders

Powtech inverters are using a more ergonomic keyboard------4.3 inches standard size and can

be operated wih one hand; 10000 times mechanical stretch feedback buttons and specially designed anti-slick bump high precision rotary encoder(control precision is 0.01Hz);Support keyboard hot-pluggable and allow users to remove and replace the keyboard without shutting down the system or cutting off the power; can store/copy 4 groups of operating parameter programs, parameters unload, download and there are progress indicator for copy. And can select to prohibit to upload the parameter which has been unloaded in case of coverage.

English menu display and LED/OLED options

The Powtech inverter is equipped with OLED operating keyboard display menu and there are

two default languages: Simplified Chinese and English. The users can set the display language freely according to the usage habits; According to customer needs , it also support the

extension and display of multiple languages. If you need special language version, you can also be in consultation with us.

Parameter copy function is embedded in the OLED external keyboard and the parameters will restored to 0 after the copy operation is completed.

Intelligent constant pressure water supply on/off control

Powtech inverter with smart start-stop control, can realize to sleep or wake up in the water supply.

P14.00	PID arithmetic	0: stop operation 1:stop computing
P14.01	Wake frequency	The Sleep frequency- maximum frequency
P14.02	Wake latency	0.0s~3600.0s
P14.03	Sleep frequency	0.00Hz~wake frequency (P14.01)
P14.04	Sleep delay time	0.0s~3600.0s

Motor parameters self-learning

Powtech inverter adopting precise sensorless vector control technology and professional torque control technology, has a fast response speed and self-learning accurately to stator, rotor, resistance, inductance, mutual inductance and other parameters with good effect, and can be set intelligently to optimal control model.

P03.11	Motor parameter self-learning	0: no operation
1: parameter comprehensive learning
2: parameter with static self-learning

Set P03.11 to 1 and then press "data confirm key" to start motor parameter learning, the LED show "-TUN-" and flashing, and then press the "Run" key to self-learning; when it displays "TUNE0" and "TUNE1", the motor starts to run and the "RUN/TUNE" lights flash. When the parameters self-learning is completed, it displays "-END-" and finally back to the stop state

display interface. When the "-TUN-" flashes, it can be set "Parameter setting in/out button" to

exit the parameter self-learning. During the process of parameter self-learning, you can press the "stop/reset" butoon to stop parameter self-learning
