command in the following situations, this
error will occur:
1. Feedback position register

AL283 Forward software limit Issue alarm reset to clear this alarm
Causes Checking Method Corrective Actions
Forward software limit Forward software limit is determined by
position command, not the actual
feedback position. That is because the
command always arrives first and then
the feedback. When the protection
function is activated, the actual position
might not exceed the limit yet.
Therefore, setting an appropriate
decelerating time could satisfy the
demand. Please refer to the description
of P5-03. Issue alarm reset
AL285 Reverse software limit Issue alarm reset to clear this alarm
