Bldc wide voltage 5-50V high power 380W dc three-stage brushless sensor controller recognition PWM signal input amplitude 3-5V support PLC 0-5V External signal input special description: - external signal input when switching PWM input mode through the input button of the terminal input, input PWM signal speed regulation amplitude 3-5V frequency 1K-10K best (on board auto-band potentiometer to minimum memory) - input of external signals 0-4.5V dc voltage signal speed control for switching analog input mode via the input button of the terminal, up to a maximum of 5V (on the board with the auto-band potentiometer to the minimum memory) - positive reverse braking stops keeping low level effective through a switch grounding, or external MCU can give low level signal, the front row control end of which is a weak electrical signal directly into MCU main control, cannot touch and contact high voltage strong current. Interface description: 1.U V W 3 phase dc output adapter brushless motor 2. 5V GND main board self-belt 5V (external output current not exceeding 50MA) 3.Vcc GND drive main power supply (external dc source) 4.Sc speed pulse signal output (only interface is left without technical support) 5.Dir positive reverse control to keep low level effective (can be docking off switch) 6.Brake control active brake to keep low level effective (docking switch) 7.Sotp stop control to keep low level effective (off-site switch) 8.0-4.5V & PWM speed control signal dual input end (on board self-belt potentiometer speed control can also be external 0-4.5V-feel PWM-to-take-up signal input speed control) Warm tip: drive is the company's own development products, circuit schematics not provided, please understand, the anti-copying board is partially IC polished, mind the careful use of software and hardware parameters fine adjustment without prior notice Main board specification parameters: Product name: ZS-X11F V1 Working voltage: 5-50V (limit 60V) Drive current: rated 16A plus wind cooling cooling 25A Maximum power: 380W Overcurrent protection: yes Stop protection: yes (auto-drop current after stopover) Over-Temperature protection: yes (half over-temperature power) Maximum speed:224000 Rpm (2 polar motors), 74000 RPM (6 polar motors), 4000 RPM (12 polar motors), 35000RPM (14 polar motors). Points to note: - the negative and positive polarity of the power supply on the main board can cause permanent damage to some of the chips on the board (not for a few seconds) - sampling overcurrent protection at the output end of the motor during normal operation. as the power current of the module is very high, please do not make a short-circuit when the module is not working properly, but the short-circuit has the possibility of firing line explosion. the first circuit test machine should use a low-current test.Voltage contact plate parts - do not connect motors that are clearly inconsistent with or far from the power of the voltage current of th
