Note. CNC EMERG. will always be assigned to I1/O1 of the PLC with an 8055/55i CNC. With an
8070 CNC, it may be assigned to any I/O of the PLC. The contacts associated with relays - KA2, -
KA3, - KA4, - KA5, - KA6 and - KA7 are shown inside a circle in figure
F. H10/12 and the contactor -
KM1 in figure F. H10/14 .
Note. The relay - KA3 uses delayed
deactivation (t seconds) maintaining
the DRIVE ENABLE control signal
active for a few seconds to maintain
motor torque while the vertical axis
holding brake is enabled.
See parameter GP9 in the
“man_dds_soft.pdf” manual.
