5.5 SIMODRIVE POSMO A functions
The ”traverse to fixed endstop” function can be used as follows for
referencing:
Set the current to a permissible value for the fixed endstop.
– P28 (max. current) = ”required current”
– P16 (max. overcurrent) = ”required overcurrent”
Suppress the ”speed controller at the endstop ” fault.
– P30.0 = ”1” ”Speed controller at the endstop” fault
––> is redefined to become a warning
Traverse to the fixed endstop by jogging
When the endstop is reached, it is displayed as follows:
– ZSW.7 = ”1”
and
––> means ”warning effective”
– P953.7 = ”1” ––> means ”speed controller at its endstop”
Cancel jogging
Set a valid position actual value for the fixed endstop position
– Write a valid position actual value into P40
P40 = ”requested actual value” Position actual value
or
– Assign a valid position actual value from P5
The position of the last zero mark is set to the value in P5 (reference
point coordinate) by ”start referencing” and ”stop referencing”
(STW.11).
The actual position to be written is corrected by the distance
which was traveled since the last zero mark.
Set the ”stop referencing” depending on ”reference point set”
(ZSW.11).
