4. Understanding of small XY Drivers circiuit 5) The circuit of Sampling Signal -Compare the current value of Motor + Pulses value with Sampling waveform, and then set the VR4 for output FET waveform. So it output Sampling triangle waveform ( 16.2-19.8Khz) 3. Circuit Interaction # XY Driver Board

4. Understanding of small XY Drivers circiuit 6) The function current Controller and FET Driving PWMs waveform CircuitContent (The function of current Controller) - PD controller apply current controller as preventing outputs current down by reverse-power of motor (FET Driving PWM s waveform) -The 5V PWM is occurred by FET driving waveform - It stays about 1.09 sec s Dead Time in each PWM s wavefrom. 1 : 1 3. Circuit Interaction # XY Driver Board SWF 65/76 Page

4. Understanding of small XY Drivers circuit 7) the function of current Amplifier circuit Content - the motor is working when the driving current of each driving signal is input. This process is PWM waveform made by current controller through current Amplifier and then swicthing the FET. 8) The function of current FeedBack s circuit - When the motor is working, through Motor coil and current sensing resistance, Motors cable current value is sensing. This current is transfer to torque controller. 3. Circuit Interaction # XY Driver Board SWF 66/76 Page

IC Multi vibrator The multi vibrator is Each trigger and reset control of dual state. This can re-trigger and re-set, control input is luached inside. SWF 68/76 Page

CD4538BC is Exact Single Multi vibrator, control Trigger and Reset of Dual function separately. This can be Re-trigger and reset, the control input launch inside. Two triggers input can choice between up and down trigger. Reset input is LOW Active Mode, in active mode it cant use a trigger function Exact control of output Pulses range can possible by CMOS technology. The Pulses cycle and precision is depend on Rx and Cx of outside. When the power off, this dont permit a discharge of electricitys timing condenser by timing Pin.
