Note.
Observe that having the main switch - S1 closed, although the power contactor - KM1 is open, the internal auxiliary
power supply remains connected to the unit through its connector X1 to feed the control circuits of the drive.

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 fig.
and the contactor - KM1 in fig.
.
Important.
The relay - KA3 acts simultaneously upon contact KA3,1 to excite the coil of contactor - KM1 and upon the
auxiliary contact KA3,2 (see previous figure) associated with the PWN ENABLE (pin 4 of X6) of the RPS power supply.
Make sure that the time «t» used to program the off-delay of relay - KA3 associated with contacts KA3,1 and KA3,2 is
greater than the braking time (full stop) to permit returning all the excess energy to mains while braking.
Note.
See also auxiliary early
open contacts K1 and K2 in the
previous figure.
