1.1 Overview
1.1.1 Properties
Properties of ADI4 module
An ADI4 module (Analog Drive Interface for 4 Axis) is an interface module suitable for
running up to four drives with an analog setpoint interface on the equidistant PROFIBUS DP.
Communication between the controller and the ADI4 is performed via an ADI4-specific
message frame type which, in addition to digital input/output data, also contains a message
frame type (standard message frame 3) for each drive specified according to a PROFIDrive
profile. As part of cyclic DP communication, the actual drive values (encoder values) are
transferred from the ADI4 module to the controller via PROFIBUS DP, and the speed
setpoints calculated by the controller are transferred to the ADI4 module.
The transferred speed setpoints are then output from the ADI4 module to the drives as
analog values.
1.1.2 Essential features
Features of the ADI4 module
The module has the following essential features:
● PROFIBUS DP connection (maximum of 12 Mbits/s)
● 4 servo interfaces
– Inputs: TTL/SSI encoder for incremental and absolute measuring systems
– Outputs: ±10 V analog
● General and drive-specific digital input/output signals
● On-board status display via four diagnostic LEDs
To supply the module and digital outputs with power, an external voltage source (+24 VDC)
is needed.
