Note: Whenever a command is sent, the LAC will echo back the command. The
exception is SET_POSITION, which returns the current position.
0x01 SET_ACCURACY:
This is the value controlled by the Accuracy Potentiometer. A value between 0-1023 is
accepted. When the feedback position is plus or minus this value, the actuator will stop
moving. Reducing this too far will result in the actuator continuously moving back and
forth, never reaching the set point. The default value is four. To find the equivalent
distance, use the formula:
For example, a value of four will give you +/- 0.117mm accuracy when controlling a
30mm actuator.
0x02 SET_RETRACT_LIMIT and 0x03 SET_EXTEND_LIMIT
These are the values that are set with the Limits Potentiometers. Setting the
Extend_Limit to 1023 and the Retract_Limit to zero will allow movement over the full
range. However, it is recommended to offset these values to ensure the actuator is never
driven into the physical end stops. This increases cycle life considerably. To set the
desired limits take the distance (mm) from the physical stop you wish to limit the actuator
to, and plug it into the following equation.
