Manual, 05/2009, 6FC5 297-0BA01-0BP6 9
General 1
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.

1.1.4 Boundary conditions
Boundary conditions for the ADI4 module
The following boundary conditions must be taken into account for the module:
● An ADI4 DP slave can only be operated on an equidistant PROFIBUS DP.
● An ADI4 DP slave is not a certified DP standard slave as defined by the PROFIDrive
profile. For example, the ADI4 DP slave does not enable acyclic communication.

Note
If cable lengths longer than 25 m or 35 m are needed for incremental encoders, encoder
types with a 24 VDC supply voltage can be used instead.
CAUTION
To ensure error-free transmission of encoder data, do not exceed the maximum cable
lengths shown in these tables.

Connectable measuring systems
Incremental encoder (TTL)
● Differential transmission with RS 422 and operating voltage 5 V or 24 V:
– Track A as true and inverted signal (Ua1, /Ua1)
– Track B as true and inverted signal (Ua2, /Ua2)
– Zero signal N as true and inverted signal (Ua0, /Ua0)
● Maximum output frequency: 1.5 MHz
● Phase shift of Track A to Track B: 90° ± 30°
● Current consumption: Max. 300 mA
● Encoders with distance-coded zero marks/reference marks are not generally enabled.
Absolute encoder (SSI)
● Transmission method: Synchronous serial interface (SSI) according to RS 485 with 5 V
differential signal transmission (RS 422 standard)
– Output signal: Data as true and inverted signal
– Input signal: Shift clock as true and inverted signal
● Data transmission format: "Pine tree"
● Resolution: maximum of 25 bits
● Maximum transmission rate: 1 Mbit/s
● Current consumption: Max. 300 mA
The following SSI encoders are supported:
● All SSI encoders in the pine tree format whose MsgLength is equal to the number of
"significant data bits":
– 25-bit with 12-bit multiturn and 13-bit single-turn information (setting of the
MsgLength 25)
– 21-bit with 8-bit multiturn and 13-bit single-turn information (setting of the
MsgLength 21)
– 21-bit with 9-bit multiturn and 12-bit single-turn information (setting of the
MsgLength 21)
– 13-bit with 13-bit single-turn information (setting of the MsgLength 13)
● SSI encoder in the pine tree format with the following data:
– 25-bit with 12-bit multiturn and 12-bit single-turn (setting of the MsgLength 24)
– 21-bit with 8-bit multiturn and 12-bit single-turn information (setting of the
MsgLength 20)
– 13-bit with 12-bit single-turn information (setting of the MsgLength 12)
– This applies as long as the encoder permits that not all available data is read!
● All right-justified encoders that satisfy the first condition indicated above.
