OPERATION DIAGRAM. ACD/SCD
Note 1.The relay KA3 uses
delayed deactivation (t sec-
onds) 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.
Note 2. 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 - KA3, - KA4 and - KA6
are shown inside a circle in fig-
ure F. H10/21 and the contactor
- KM1 in figure F. H10/24.
