The interface is linked to the external PC by direct
electrical connection. This may lead to interference in the
interface, resulting from different power-supply reference
levels.
Measures:
■
If possible, use the service jack on the machine for the
PC.
■
Engage/disengage the connection only when the
machine and PC are switched off.
■
The cable length must not exceed 20 m (66 ft). Use even
shorter cables if there is strong electromagnetic
interference.
■
Recommendation: Use an adapter with electrical
isolation.
11.3 Peripheral Interfaces
The CNC PILOT is fitted with the following connectors for connecting
peripheral devices or PCs and for integrating the control into
networks. For information on the connectors available on your lathe,
refer to your machine manual.
