NEGATIVE VALUE IN TIMER PRESET OR ACCUMULATOR

What does 0034 mean?

A negative value was loaded into either the preset or accumulator word of a timer instruction. This is a recoverable fault, as timer values (presets and accumulators) are typically non-negative and negative values are not logically valid for timing functions.

• Program logic attempting to move a negative value into a timer's preset or accumulator word.
• Arithmetic operations within the program leading to a negative result that is then incorrectly assigned to a timer parameter.
• Data input from an external source provides a negative value to a timer parameter.

Click steps to track your progress.

1. 1

   If the program is moving values to the accumulated or preset word of a timer, verify these values are non-negative.

2. 2

   Adjust the program logic to ensure only positive or zero values are assigned to timer presets and accumulators.

3. 3

   Reload the program and enter the Run mode after making corrections.
