AN-CM-247 Servo Overload Protection
■Servos are one of the most used actuators in robotics. Some servos, especially unprogrammable servos, do not have overload protection. Consequently, a user will only find that the servo was overloaded after it has become noticeably burnt. This application note provides a design to try to protect an unprogrammable servo from overload risk caused by mechanical problems. This design uses an SLG46140V GreenPAK. There are two designs, the first one uses an absolute value for a failsafe PWM that sets when overload is detected. The second uses a delay block to increase or decrease the PWM duty cycle relative to the input when overload is detected.
■This application note comes complete with design files which are listed in the References section.
