If an axis is at a hardware limit switch, then it can be moved away as
follows:
Return the axis to the valid traversing range
– Move away jogging in the opposite direction to the approach
direction
or
– Withdraw the controller enable and move the drive away manu-
ally
Withdraw controller enable (terminal 65.x)
Acknowledge the fault
The minus software limit switch (P0315) and the plus software limit
switch (P0316) must be appropriately set to limit the working range or
to protect the machine.
Notice
The software limit switches only become active if the following
conditions exist:
The function is activated via P0314
The axis is referenced (”reference point set” output signal)
Only then is it certain that the axis will be immediately stopped if it
attempts to move out of the permissible range.
Note
The SW limit switch monitoring is dependent on the axis type as
follows:
For a linear axis or rotary axis with modulo correction, the following
is valid:
The software limit switches can be activated via P0314 and set via
P0315 and P0316.
For rotary axis with modulo correction (from SW 2.4), the following
is valid:
The software limit switches are automatically de–activated. If
monitoring is parameterized, it has no effect.
The status of a software limit switch is displayed using the following
signals (refer to Chapter 6.4.5):
”Minus software limit switch actuated” output signal
or
”Plus software limit switch actuated” output signal
