external voltage (24 V) whose reference potential should be connected to X21 pin 10
Setting machine data
The following machine data should be checked and adjusted if necessary:
● MD13200[0] $MN_MEAS_PROBE_LOW_ACTIVE = 0 or 1
● MD13200[1] $MN_MEAS_PROBE_LOW_ACTIVE = 0 or 1
– Value 0 = deflected state 24 V (default)
– Value 1 = deflected state 0 V
You can access this machine data through the following operations:
+ → → →
