Fig. 6.11−2 Active data field (RAM1) and background data field (RAM2)
ƒ Background data field (buffer storage RAM2)
During operation, the controller can already save new profile data in the
buffer storage (e.g. for preparing a product change−over). This profile
data is not yet active.
ƒ Active data field (main memory RAM1)
Profile data in this data field is immediately active. If you accept profile
data, the active data in the main memory will be overwritten.
Inhibit the controller (X5/28 = LOW) before loading profile data into the
main memory to prevent uncontrolled motor movements.
As long as the controller is enabled, you may only accept profile data
which − compared to the active profile data −
– has slightly changed in the start and end point,
– has the same number of interpolation points,
– has the same distribution of interpolation points,
– has the same data model.
