I/O modules

For A/D conversion, the analog output current of the clearance sensor must be connected to
NC via an I/O module with analog input to the NC.

I/O modules (840D)

The analog I/O module (DMP compact module) is connected to the drive bus via an NCU
terminal block.

Suitable I/O modules
As the A/D conversion time directly affects the deadtime of the clearance control servo loop,
only one I/O module may be used with low conversion time.
An I/O module suitable for clearance control is:
• DMP compact module 1I, NC analog
Conversion time: 75 μs
Order number (MLFB): 6FC5 211-0AA10-0AA0
