BlueBird BMS-621DMG
Hi guys, I am new to the world of servos and have just purchased my 1st servo, a Blue Bird BMS-621DMG+HS. When the servo is not powered, if I have to turn te servo arm by hand, it rotates freely just over 180 degrees. However, when I try to send a pulse to the servo, I am only able to control it from just after 0 degrees to around 130 degrees. The servo responds to a PWM on timeof 0.9ms (@ around 10 degrees) to 2.1ms (@ 130 degrees) with a period of 20 ms. Would really appreciate some help!
