SINUMERIK 810D Equipment Manual Configuration CCU (PHC) – 03/2006 Edition

The PE conductor connection is also used to conduct interference currents

away from:

 the shields of the DMP casing,

 the DMP compact plug-in modules,

 the 24 V logic power supply.

To ensure that these interference suppression measures are effective, there

must be a low-resistance connection between the shielding plate and ground

potential.

The low-resistance bonding conductor should be a stranded cable with a cross-

section of at least 10 mm

and a length of less than < 30 cm, if possible.

A maximum of 8 DMP compact modules can be connected per NCU terminal

block.

Module type Max.

Important

A maximum of 4 analog outputs and 4 analog inputs can be plugged in at the

same time for each NCU terminal block.

Caution

After the load supply voltage for the DMP compact modules has been switched

off during operation, the outputs do not reliably reestablish through-connection

when the load supply voltage is switched on again. If switch-off during

operation cannot be avoided, the DMP outputs have to be reset via the PLC

program when the load supply voltage is switched off. The outputs are set

again after the voltage has been switched on again.
