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 in
F. H10/13 and the contactor - KM1 in fig. F. H10/14 .
Important. 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.
