Activation / deactivationActivationThe passive position measuring system of a machine axis is parked under the followingconditions:● "Park passive position measuring system" function is active for the measuring system:MD31046 $MA_ENC_PASSIVE_PARKING[] = 1with = 0 (position measuring system 1) or 1 (position measuring system 2)NoteMD31046 is not active:● for axes with fewer than two encoders:MD30200 $MA_NUM_ENCS < 2● for simulated encoders:MD30240 $MA_ENC_TYPE = 0NoteFor position measuring systems, which are used as motor measuring systems, the "Parkpassive position measuring system" function should be deactivated (MD31046 = 0)!and● The user sets the following NC/PLC interface signal to "0":DB31, ... DBX1.5 (position measuring system 1) = 0orDB31, ... DBX1.6 (position measuring system 2) = 0The controller then sets the status for the activation state of the position measuring system to"0":DB31, ... DBX102.5 (position measuring system 1 activated) == 0orDB31, ... DBX102.6 (position measuring system 2 activated) == 0The position measuring system is now no longer monitored and updated.Deactivation"Park" is deactivated if the user activates the position measuring system:DB31, ... DBX1.5 (position measuring system 1) = 1orDB31, ... DBX1.6 (position measuring system 2) = 1The controller then sets the status for the activation state of the position measuring systemback to "1":DB31, ...
