    Note A pneumatic positioning axis should be operated with at least the minimum total load (è www.festo.com/catalogue). If necessary, this minimum mass load must be ensured through the use of an additional weight. The payload present can be specified for each positioning command. The controller setting of the CMAX can thus be adjusted to various loads.
