Minimum quantity of a batch:
The minimum quantity is the lower limit for a concrete quantity. In the batch planning a check
is made to ensure that the quantity is not less than the value entered here.
In the parameters of the recipe phases (EOP/EPH) and the operator dialogs (OD), this value
is included in the calculation when determining the lower limits. If the minimum quantity is too
low, this may mean that the lower limit of the parameter is violated by quantity scaling.
Maximum quantity of a batch
The maximum quantity specifies the upper limit for a concrete quantity. Batch planning makes
sure that the quantity does not exceed the value entered here.
In the parameters of the recipe phases/operator dialogs, this value is included in the calculation
when determining the upper limits. If the maximum quantity is too high, this can violate the
high limit of the parameter after quantity scaling!
Note on specifying amounts
Note
The entries made for reference quantity, minimum quantity and maximum quantity of a batch
are the basis for all quantity-dependent parameters in the master recipe. The parameters also
have an upper and lower limit value.
When using linear/squared scaling functions, avoid using a master recipe for both large and
small batch quantities. Otherwise, this can lead to scaled setpoints being outside the parameter
limits. If these limits are exceeded, this is detected during validation and displayed as a
"Warning".
Additional help: The setpoints derived per parameter from the specified reference quantity,
minimum quantity and maximum quantity of a batch are displayed as a tooltip for each
parameter value in the "Input material", "Output material" and "Parameters" tabs.
Example – High limit 10000 violated:
● In the "Product" tab: reference quantity = 600, minimum quantity of the batch = 400,
maximum quantity of the batch = 800
● In the "Parameters" tab: low limit = 0, value = 9000, high limit = 10000
Result: The settings maximum quantity = 800, reference quantity = 600 and setpoint = 9000
result in a scaled setpoint of 12000, however the maximum for this parameter is 10000. For
this master recipe the maximum quantity of the batch of 800 is too great, it should be a
maximum of 666,667.
