Synchronized Movements Of Multiple Units - Wahlberg Track Runner Series User Manual

Synchronized movements of multiple units

If several units 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,
and some motors have a slightly higher maximum speed than others.
Like when fading light, the positions of the different units should be faded, and the units 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 units will move at the maximum speed, and you will see
the difference in the motor speed.
If the fade is to slow the units will move – stop – move – stop, when the position changes, thus
giving a discontinuous movement.
