Setting the left and right positions (DMX operation)
When the unit is ready, the first step is to set the soft-limit left and right positions. See channel
description for channel 4, 5 and 6 on the previously page. When the range has been set once on
channel 6 it is saved and does not need to be set again unless a new range is needed, or when the
unit has been manually operated or removed from the track.
Example:
−
DMX channel 6 is set to 53% → Soft-limit save enabled.
−
DMX channel 4 is set to 30% → The motor starts move reverse (to left).
−
DMX channel 4 is set to 0% → The motor stops, and the soft-limit left position is saved
at this point.
−
DMX channel 5 is set to 30% → The motor starts to forward.
−
DMX channel 5 is set to 0% → The motor stops, and the soft-limit right position is also
saved.
The unit is now ready for use and the soft-limit left and right positions have been saved. Finally,
the position control with channel 1 and 2 is now relative to the left and right position adjusted.
It is recommended to set the soft-limit left position after each power-up, however, moving the
motor to the left position before powering off should lead to identical left and right end positions
whenever the unit is repowered, provided that the motor position was not manually changed or
the motors return to the left position was interrupted by a power failure, furthermore excessive
transportation conditions may also affect the motor position.
For further guidance see below illustration for application of the soft and hard-limits.
