2.13 ADI4 (analog drive interface for 4 axes) (SW 09.01 and higher)
The interface module ADI4 is suitable for operating up to four drives with an
analog setpoint interface on the PROFIBUS DP.
The module has the following important features:
PROFIBUS DP connection (max. 12 Mbit/s), in accordance with:
PROFIDrive profile drive technology version 3,
Draft V1.4.2, 01. September 00
Four servo interfaces each with one:
– Input: TTL/SSI encoder for incremental and absolute measuring systems
– Output $10V analog
General and drive-specific digital input/output signals
On-board status display by means of four diagnostic LEDs
To power the module and the digital outputs, an external power supply source
(+24VDC) is required.
Please observe the following framework conditions for operating the ADI4 DP
An ADI4 DP slave can only be operated on an equidistant PROFIBUS DP
(see Subsection 7.3.6, page 7-220).
An ADI4 DP slave is not a DP standard slave certified as compliant with the
PROFIDrive profile, e.g. the ADI4 DP slave does not support acyclic com-
