Positioning
When the unit has been setup and the soft limits is set, it is possible to use it for positioning run.
The position is set on the DMX channel 1 and 2, which controls the rough-and fine-position. Where
100 % is the right position(forward) and 0% is the left position(reverse).
The positions lamp indicates, by fast flashing, that the unit is going towards the wanted position.
The position lamp indicates, by stable light, that the unit has found the wanted position and the
motor has stopped.
The speed is set on the DMX channel 3, where 100 % is the fastest and 0 % is the slowest.
The unit does not run unless DMX channel 3 is set above zero, and therefore this channel works
as a main brake.
Duty-cycle
When the unit is continually operated for more than 30 minutes at full load, speed and high
ambient temperatures, the below duty-cycle (DC) limitation will need to be considered.
The duty-cycle (DC) is the fraction of a period where the motor is active. The duty-cycle is
commonly expressed as a percentage or ratio. Its described as the period it takes for a system to
complete an on-and-off cycle.
Thus, a 10% duty-cycle means the system is on 10% of the time and off 90% of the time
. The “on
time” for a duty-cycle is normally related with a cycle length in time. E.g. a max duty-cycle of 50%
(30 min. ON / 30 min. OFF), means that the motor may not be active for more than 30 minutes
every hour, or after 5s ON the motor must be OFF for 5s if continually operated for more than 30
minutes.
