DBX102.5/6 Position measuring system1/2 activated
Edge evaluation: No
Signal state 1 The position measuring system is in the "active" or "passive" state. Monitoring and updating the
position measuring system is activated.
Signal state 0 The position measuring system is in the "Park" state. Monitoring and updating the position measuring
system is deactivated.
"Parked" status is entered if:
● for the axis/spindle, the NC/PLC interfaces signals for the configured position measuring systems
● "Parking the passive measuring system" is active for the measuring system:

and control enable are reset:
– DB31, ... DBX1.5 (position measuring system 1) = 0
– DB31, ... DBX1.6 (position measuring system 2) = 0
– DB31, ... DBX2.1 (controller enable) = 0

– MD31046 $MA_ENC_PASSIVE_PARKING[<n>] = 1
with <n> = 0 (position measuring system 1) or 1 (position measuring system 2)
and the NC/PLC interface signal for the position measuring system was reset to "0" by the user:
