5.2.11 CPCI-8004 pin assignment connector P1, release relay

At connector P1, relay points are provided for the CNC-ready request and amplifier release. These are
'normally open' contacts. After the PC is switched on, all relays are switched off after a reset action or an
error.
The release relay is activated for the respective selected axis channel by using the cl() command for PCAP
and the CL() command for SAP.
Note: Depending on the configuration level of the CPCI-8004, 1 to 4 relay outputs are available.
The connections could be made via a 25-pin SUB-D connector (see Options Manual).

5.2.12 Connection and wiring instructions

5.2.12.1

Earth and current supplies

The xPCI-800x is divided up electrically into two zones. Each zone has its own reference potential, although
the different zones are electrically isolated from each other. The first zone contains the xPCI-800x system
logic (CPU, memory, etc), and the second zone contains the pulse acquisition (encoder), setpoint value
generation and the digital input-output logic. This separation offers maximised protection of the various
modules, prevents earth loops and circuits, and provides a high level of immunity to interference from
interfering signals, which are often spread from the drives via signal and earth connections.
5.2.12.2

Potential equalisation

Since the above-mentioned supply zones are completely electrically isolated from each other, potential
differences of several kV can occur between these zones. To prevent this, potential equalization should take
place between the individual zones. This can take place by earthing all supply voltages or through potential
equalisation networks on the xPCI-800x.
