Feedback Zero
Sets feedback signal zero raw count value. Value is scaled between 12 bit count of 0 and 4095 for the selected
command type range. When selected, use [UP] or [DOWN] to adjust feedback until desired value is measured.

Feedback Span
Sets feedback signal span raw count value. Value is scaled between 12 bit count of 0 and 4095 for the selected

Sets type of feedback for positioning.
Limit SW:
Uses limit switch feedback for 2 position on/off control.

Calibrate Close
Position
Only used with potentiometer feedback to set close position. This position will correspond to a 0% input value.
Value is scaled between 12 bit count of 0 and 4095 based on potentiometer reading. When selected, use [UP] or
[DOWN] to drive motor to desired close position.

Calibrate Open
Position
Only used with potentiometer feedback to set open position. This position will correspond to a 100% input value.
Value is scaled between 12 bit count of 0 and 4095 based on potentiometer reading. When selected, use [UP] or
[DOWN] to drive motor to desired open position.

Travel Timeout
Only used with communication bus options. Value should be greater than the normal actuator travel time. The
TMC-4 begins a counter when the motor outputs are energized to control the actuator to the commanded position.
If the counter exceeds the set value it can indicate a jam or obstruction. The actuator may also be travelling slower
due to loading conditions. When selected, use [UP] or [DOWN] to adjust value. Can also be configured via
communication protocol.
