Current workpiece mass.
Deviations from the actual mass load worsen the positioning behaviour. From mass changes of apĆ
prox. 30%, the current mass should be specified. The total moving mass is the sum of workpiece
load without workpiece (PNU 1142) and workpiece mass.
For vertical installation, the correct workpiece mass is absolutely essential in order to calculate the
zero force of the force control. An error in the data can lead to a movement of the axis if the default
is 0 N.
Default values: For position control:
RPC bit 5
Default value from parameter PNU 605
For force control:
RPC bit 5
Default value from parameter PNU 605
o
The parameter value cannot be changed.
o
Writing permissible only in commissioning/parametrising mode with disabled controller.
ý
This parameter can be written by FCT without higher−order controller.
o
After writing, controller recalculation is carried out.
