Workpiece loaded at power−on

PNU

PNU: 1143

Index: 1

Max index: 4

Class: Var

Data type: int32

Values

Without unit

Default: 0

Minimum: 0

Maximum: 1

If a controller is enabled, the last valid workpiece mass is always used. After the first enable after
switching on, usually no workpiece is loaded, so CMAX only takes into account the basic mass withĆ
out a workpiece (PNU 1142). This parameter defines whether the workpiece should also be taken
into account when switching on.
0 = Workpiece not loaded when switching on.

The workpiece is only loaded during operation.

1 = When switching on, the workpiece is already in the loading device.
Note: With every positioning command either the default value (PNU 605) or the value from the indiĆ
vidual parameter (PNU 410, 536, 544 or 551)in the controller is used for the workpiece mass. As
soon as the first positioning process has occured after switching on, the parameter Workpiece mass
when switching on" will have no effect any more.

o

The parameter value cannot be changed.

ý

Writing permissible only in commissioning/parametrising mode with disabled controller.

o

This parameter can be written by FCT without higher−order controller.

ý

After writing, controller recalculation is carried out.

Dual axis design

Parametrising a dual axis.
With a parallel axis, two parallel drives/cylinders are mechanically coupled and controlled jointly. The
second axis has no measuring system, so only one axis is controlled − the other one is simply also
supplied with compressed air through the valve. The double effective piston surface is automatically
calculated by the CMAX and does not need to be entered.

0 = Design as single axis
1 = Design as dual axis

o

The parameter value cannot be changed.

ý

Writing permissible only in commissioning/parametrising mode with disabled controller.

o

This parameter can be written by FCT without higher−order controller.
