100W Dc6-24v Bldc Three-phase Hall Controller Brushless Motor Drive Board

2& 12289;VCC GND main power supply (external DC power supply) 3, PWM external duty cycle speed signal input (PWM signal amplitude 3-5V frequency 1KZ-20KHZ) This interface supports the connection of 5V full-speed operation, grounding stop operation 4, FG speed pulse signal output (only leave the interface) 5, DIR forward and reverse control interface (low-level effective, can be connected to the ground external switch) 6& 12289;BRAKE brake control interface (low-level effective, can be connected to the ground external switch) Notes: 1, the motherboard power supply circuit without a fuse, it is recommended to add their own, the power supply positive and negative polarity reversal will cause permanent damage to some of the chips on the board (that's not even 1 second) 3, the module power is small (maximum 100W) overload capacity is weak when using the use of spare capacity, can not be connected to high-power motor work or test machine, forced to work with the risk of impact damage to the power tube, it is recommended that the use of power 12V power supply 42W 24V power supply within 84W 4, do not connect the obvious and drive module voltage current power phase does not match or far from the motor, to avoid inexplicable damage 5, due to the forward and reverse is no delay hard commutation, as well as high-speed braking will have a great impact, so it is not recommended in the high voltage full-speed operation of these two functions, the need to speed throttle down to 50% or below can be forced to operate the power tubes and chips may be damaged Package include: Speed controller *1 Wiring *1
