Synchronized movements of multiple rotators
If several rotators are installed to perform synchronized movements the best result is achieved
by using a fading 16 bit position. By nature there is a slight deviation in performance of the
motors so some motors have a slightly higher maximum speed than others.
Like when fading light, the positions of the different rotators should be faded, and the rotators
will tend to follow that fade. When fading the positions:
1.
The speed channel should be a set to 100 to gain the highest possible speed.
2.
The position channel should be added as a 16 bit channel and not just the MSB on
channel 1.
3.
The speed of the fade needs to be slower than the maximum speed, so the motors have
speed enough to perform the movement.
If the fade of the positions is too fast, the rotators will move at the maximum speed, and you will
see the difference in the motor speed.
If the fade is to slow the rotators will move – stop – move – stop, when the position changes,
thus giving a discontinuous movement.
