3. Special
SmartWinch
Features
Dynamic
Pulse Width Modulation
Servo systems use Pulse Width Modulation to reduce power and speed
as the desired position is approached. This gives finer and smoother control when
small movements are required. But the problem with standard P.W.M. is that as
the desired position is approached, the reduction in power can cause the servo to
stop short. This can result in excess power consumption, overheating and
damage. This is what's happening when a servo is not moving but is buzzing.
However, unlike other winches and servos the
SmartWinch
has dynamic P.W.M.
If the
SmartWinch
controller detects that it has not reached the desired position,
it will increase power up to 100% if necessary until it does. If once 100% power
is reached and the
SmartWinch
is still not able to reach its desired position then
the stall protection feature can be activated.
