3.27 HSCI Adapter for PLB 6001 OEM-Specific Machine Operating Panel
HEIDENHAIN offers the PLB 6001 HSCI adapter with HSCI interface for con-
necting an OEM-specific machine operating panel.
On the underside of the machine operating panel are terminal strips bearing
the PLC inputs as well as the PLC outputs. Also, connection X23 for HR hand-
wheels is on the underside of the PLB 6001 (see "Handwheel Input" on page
287).
Please note that the PLB 6001 is supplied with +24 V NC.
For the entire HSCI system, the +24 V NC supply voltage is required to be
safely separated voltage. The +24 V NC supply voltage must not, under any
circumstances, be connected with the +24 V PLC supply voltage, because
this removes the double basic insulation.
