triggered and the homing
procedure is not complete.
5. AL.060 and AL.062 occur.
Checking Method
Indexing coordinate is undefined
and then execute index positioning
command.
Checking Method
Forward Software Limit is
determined by the position
command, not the actual feedback
position. It is because the command
will arrive first and then the
feedback. When the protection
function is activated, the actual
position might not over the limit.
Therefore, setting an appropriate
decelerating time could satisfy the
demand. Please refer to the
description of parameter P5-03.
Checking Method
Reverse Software Limit is
determined by the position
command, not the actual feedback
position. It is because the command
will arrive first and then the
feedback. When the protection
function is activated, the actual
position might not over the limit.
Therefore, setting an appropriate
decelerating time could satisfy the
demand. Please refer to the
description of parameter P5-03.
Checking Method
This alarm will not occur at the
moment. If it does, please contact
the distributors.
