Note. The relay - KA3 uses delayed<br />

deactivation (t seconds) maintaining<br />

the DRIVE ENABLE control signal<br />

active for a few seconds to maintain<br />

motor torque while the vertical axis<br />

holding brake is enabled.<br />

Note. CNC EMERG. will always be assigned to I1/O1 of the PLC with an 8055/55i CNC. With an 8070<br />

CNC, it may be assigned to any I/O of the PLC. The contacts associated with relays - KA2, - KA3, -<br />

KA4, - KA5, - KA6 and - KA7 are shown inside a circle in figure F. H10/9 and the contactor - KM1 in figure<br />
