Mode setting
The motor controller has three different control modes. The different modes determine which
kind of motor feedback and which type of motor regulation is used. Here are the main features.

Function
Description
1
Free Run
Run the motor forward and reverse at variable speeds and stop.
The limit switch FWD and REV is active; meaning activating the FWD
limit switch will stop the motor from running forward, and likewise for
REV.

Position
Position and direction can be controlled.
with Tacho
The limit switches will stop the motor if activated.
feedback
The motor controller calculates the position from the tacho feedback.
Manual forward on channel 5 is active. It is also used for resetting.
Manual reverse on channel 6 is active.
Resetting the forward position:
Run the motor to the forward reset position, with channel 5.
Setting DMX channel 5 to 0% resets the position.
The position after reset is set to TAC RANGE + RES OFFSET.

range, this could be at the initial motor system setup, or if the
mechanical range is changed.
After a new range has been set, it is recommended to switch back to
mode 3, to not risk changing the TAC RANGE under normal DMX
control.
Resetting the forward position:
Run the motor to the forward reset position, with channel 5.
Setting DMX channel 5 to 0% resets the position.
The position after reset is set to TAC RANGE + RES OFFSET.
Setting a new range with DMX, TAC RANGE:
First reset the forward position; then find the reverse position.
Run the motor reverse with channel 6 to the reverse reset position
Setting DMX channel 6 to 0% calculates a new TAC RANGE
The new TAC RANGE is calculated as the tacho pulses between forward
reset position, and the position reached with channel 6, subtracted RES
OFFSET x 2.
E.g. resetting forward with channel 5 to the maximum forward position
Set channel 5 to 50% motor speed moving the motor forward, until the
limit switch is reached.
Then reverse the motor to the most reverse position.
Set channel 6 to 50% speed and run the motor reverse until reverse
limit switch is reached, setting channel 6 to 0% recalculates the TAC
RANGE.
The TAC RANGE is calculated from the forward limit switch to the
reverse limit switch, where the motor controller has counted 23731
tacho pulses between the two points.
RES OFFSET here is set to 1000, then the calculation of the new TAC
RANGE = 23731 – (2x1000) = 21731. This range is instantly saved in the
motor controller.
