Enables even heat-up process until nominal SetValue of Temperature of ZoneType is reached. This stands for a process for uniform heating of a mould. Many manufacturers can do this in some form, the exact algorithms differ.
"Fast" zones on hot runner nozzles, for example, are slowed down until slower zones follow.
The aim is to keep the temperature differences in a mould low in order to protect the material from thermal damage and the mould from damage due to stress.
