I have a 4.3 HM with the Macro Damper using an SG90C servo. With the default settings of 1000us - 2000us, the servo runs continuously. I have tried various different settings in the Servo Pulse Duration with varying results. In all cases where there is any movement of the servo, it runs continuously, sometimes slower sometimes faster. Currently it is set at 1500us - 1800us. In Manual Mode this has the servo not moving until the fan % reaches 65% (% going up) and stops moving when it get to 45% going down. I just tried 1200us - 1800us. At the low percentages, it goes one direction, faster at 0% slowing down as the % increases, stopping completely at 30%. Then at the top end it starts in the opposite direct at about 85% and speeding up until it reaches 100%.
In manual mode the fan is responding correctly to the changes in %.
I am using an SG90 servo from Mouser: DFRobot Accessories TowerPro SG90C 360 Degree Micro Servo ; Mouser # 426-SER0043. This is the only SG90 servo I find in Mouser. Is this the wrong one? DFRobot's website says the neutral position is 1500us as the Wiki says in the Servo Mode.
Any suggestions would be appreciated?
