January 2012 4.9 Switching Parameter Sets 399
Conditions Conditions of the axis:
In principle, you are free to change any machine parameters of an axis
parameter set. However, when some parameters are changed, the
configuration editor triggers a reboot (RESET) of the control. These
parameters therefore cannot be switched.
If when activating or deactivating axes over the PLC you also switch
parameter sets (e.g. when exchanging milling heads), you have to observe
particular conditions, see "Writing axis information—activating and
deactivating axes" on page 678. The control checks for individual changed
parameters immediately after the change to another activation condition.
However, only those parameters are checked that are relevant for the
respective activation condition. An axis in the activation condition "manually
operated axis," for example, does not require controller parameters, and an
axis in the "deactivated axis" activation condition does not need any
parameters at all.
If the activation condition is switched over Module 9226 or 9418, the control
then checks
whether all required machine parameters are available, and
whether the machine parameters have changed since the last use of this
activation condition.
In this way, for example in a milling head exchange, an axis can be switched
to the "deactivated axis" activation condition, the parameter set can be
switched over (to other encoder configurations) and then the axis can be
reactivated.
With some parameters you have to comply with the following conditions with
regard to the switchover:
DRIVE OFF:
The motor of the affected axis must be switched off. If this is not the case,
the control releases an error message with the reaction EMERGENCY
STOP. This causes the drives to be switched off. The control conducts a
parameter-set switchover.
AXIS DEACTIVATED:
The axis must be deactivated (e.g. over Module 9226).
If this is not the case, the control issues the error message For a parameter
change the drive has to be deactivated (EMERGENCY STOP reaction).
This switches the drives off. The control does not conduct a parameter-set
switchover. If a parameter requiring the AXIS DEACTIVATED condition is
changed in the configuration editor, the change will not become effective
until the next startup of the control.
REF:
The axis concerned must be homed again after the parameter set
switchover.
