10.4 Parameter sets of axis/spindle
Per machine axis, six parameter sets are available. They are used as follows
• on an axis:
for accommodation of the own dynamic response to another machine axis, e.g. when
tapping or thread cutting on the relevant spindle.
• on a spindle:
for accommodation of the position controller to modified properties of the machine during
operation, e.g. when switching the gearbox.
Tapping, thread cutting
The following applies to axes:
• For a machine axis that is not involved in tapping or thread cutting, the 1st set of
parameters (index=0) is active in all cases.
The further parameter sets need not be considered.
• Machine axes involved in tapping or thread cutting: the parameter set is activated in
accordance with the current gear stage.
All parameter sets must be parameterized in accordance with the gear stages of the
spindle.
The following applies to spindles:
• With spindles, each gear stage is assigned a parameter set of its own.
For instance Gearbox step 1 - Parameter set 2 (Index 1). Spindles in axis operation
(DB31, ... DBX60.0 = 0) use Parameter set 1 (Index 0).
The active gearbox step can be read in the PLC via the signals DB31, ... DBX82.0-2
(Gearbox step setpoint)." The parameter set is selected from the PLC using the interface
signal DB31, ... DBX16.0 - 16.2 (actual gear stage).
All parameter sets must be parameterized in accordance with the gear stages of the
spindle.
For example, in HMI Advanced, the active parameter set of a machine axis is displayed in
the control area "DIAGNOSIS" in the screen form "Service Axis".
The active parameter set can be read in the PLC via the signals DB31, ... DBX69.0-2
(Controller parameter set)."
