Important. The relay - KA3 acts simultaneously<br />
upon contact KA3,1 to excite the coil of<br />
contactor - KM1 and upon the auxiliary contact<br />
KA3,2 (see previous figure) associated with<br />
the PWN ENABLE (pin 4 of X6) of the RPS<br />
power supply. Make sure that the time t used<br />
to program the delay of relay - KA3 associated<br />
with contacts KA3,1 and KA3,2 is greater than<br />
the braking time (full stop) to permit returning<br />
all the excess energy to mains while braking.<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, - KA4,<br />
- KA5, - KA6 and - KA7 are shown inside a circle in figure F. H10/18 and the contactor - KM1 in figure<br />

WARNING. When using an isolating transformer, the secondary must be<br />
connected in star and its middle point must be connected to GND.<br />
IT A MUST TO USE FUSES<br />
Note 1. Observe that having the main switch - S1<br />
closed, although the power contactor - KM1 is<br />
open, the internal auxiliary power supply remains<br />
connected to the unit through its connector X1 to<br />
feed the control circuits of the drive.<br />
