Synchronized movements of multiple winches
If several winches are installed to perform synchronized movements, the best result is
achieved by using a fading 16 bit position. The winches have a slight deviation in
performance of the motors, so some motors have a slightly higher maximum speed
than others.
This difference in speed can be solved by running the winches with fading positions,
like when fading conventional light over time, the position of the winch should be
faded from one position to another over a certain amount of time. In that way the
winches will follow the fade-curve, and multiple winches can follow the same fade
curve.
When fading the positions:
1.
The speed channel should be set to 100% to gain the highest possible speed.
2.
The position channel should be assigned as a 16 bit channel with
MSB
and
LSB
.
3.
The speed of the fade needs to be slower than the maximum speed, so the
motors have speed enough to follow the fade-curve.
If the fade of the positions is too fast, the winches will move at the maximum speed,
and you will see the difference in the motor speed.
If the fade is to slow, the winches will move
–
stop
–
move
–
stop, when the position
changes, thus giving a discontinuous movement.
