Important.
- KA3 is a relay for a delayed deactivation
of contactor - KM1 (t seconds) in order to
be able to keep it closed long enough to
return to mains (with XPS power supply)
t he excess ene rgy gener ated while
braking the motor.
10.
Make sure that the delay "t" programmed
at relay - KA3 is slightly longer than the
braking time of the application.
The delay disconnection time "t" to be
programmed at relay - KA3 must be
greater than the total amount of time
required to brake the motor to a full stop.
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 and - KA3 are shown in fig.
and fig.
