• is an international standard for fieldbus communication.
• is used in decentralised applications as fieldbus communication on the
lowest control level.
AS-i
Inverter Lenze frequency inverter of the "Inverter Drives 8400 motec" product series
Standard device
Drive Unit
Communication unit
Wiring Unit

»Engineer« Lenze PC software which supports you in "engineering" (parameter setting,
diagnosing, and configuring) during the entire life cycle, i.e. from planning to
maintenance of the commissioned machine.
Code Parameter which serves to parameterise or monitor the inverter. In general
linguistic usage, this term is also referred to as "index".
Subcode If a code contains several parameters, these are stored in "subcodes".
In this documentation, a slash "/" is used as a separator between code and
subcode (e.g. "C00118/3").
The term is usually called "subindex".
Lenze setting This setting is the default factory setting of the device.

CTT2 transmission
(Combined Transaction Type 2)
Serial data transmission is established between master and slave (clock in/out,
data in/out). This channel serves for ...
• acyclic transmission of data records;
• acyclic transmission of the extended process image.
Data set transmission In the case of CTT2 transmission, data records are transmitted between the
master and the slave only on request. During acyclic data record transmission,
the cyclic transmission of the extended process image is interrupted.
Process image In the case of the Inverter Drive 8400 motec, 4 bits of control data (PAA) are
transmitted to the slave every time the slave is called. The slave returns a
response containing 6 bits of information (PAE). The transmission is carried out
at least every 10 ms (AS-i cycle (31), depending on the addressing
assignment).
In the case of extended process images, continuous transmission of 4 bytes per
direction between the master and the slave takes place.
Parameter echo (diagnostics via
parameter data channel)
The "Write Parameter" AS-i command serves to transmit 4 parameter bits to the
slave.
In the response message, the slave returns 4 bits (16 bit combinations) of status
information.
ICs Circuits which efficiently perform the described tasks of a slave.

• The acyclic communication via the AS-i bus and the slave 2 are available for the read and write
access to parameters.
• The AS-i slaves can be addressed ...
• via a programming unit or from the master or
• by means of parameters (e.g. via »Engineer«, keypad or EPM).
• Up to 31 standard slaves can be connected to an AS-i network. In this case the max. cycle time
is 5 ms. Up to 62 so-called A/B slaves can be connected if extended addressing is used. In this
case the max. cycle time is 10 ms.
•Synchronisation (32) of input and output data is possible.
• Communication with the Lenze »Engineer« (access to all Lenze parameters) is executed via the

• By default, the AS-i terminal and the LEDs for the AS-i status displays are already mounted and
wired:
• AS-i connection to terminal strip X3
• LEDs on plug connector X55
• The positions A1 ... A4 and B1 ... B4 serve to freely connect the AS-i terminals, the LEDs for the
AS-i status displays and other connections (e.g. digital inputs).
• For the connections, 5-pin M12 connectors or - alternatively - cable glands (cable cross-section
max. 1.0 mm2, AWG 18) can be used.
• The M12 connectors, cable glands and prefabricated system cables can be obtained from
various manufacturers.
• Wire the M12 plugs or cable glands used with the corresponding contacts of the terminal strips
X3, X4 and X61.

4.3 Communication time
The communication time defines the time between the start of a request and the arrival of the
corresponding response.
The communication times in an AS-i network depend on the ...
• processing time in the inverter;
• telegram runtime (baud rate / telegram length);
• nesting depth of the network.
Processing time in the inverter
There are no interdependencies between parameter data and process data.
