response containing 6 bits of information (PAE). The transmission is carried out
at least every 10 ms (AS-i cycle

In the case of extended process images, continuous transmission of 4 bytes per
direction between the master and the slave takes place.

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.

Safety

• The integrated safety system can be used on machines for the protection of persons.

• The Communication Unit AS-Interface supports the services of the AS-i version 3.0:

• cyclic reading and writing of single parameters

•cyclic drive control

• acyclic reading and writing of parameter sets

• acyclic query of diagnostic data

• Two AS-i slaves are contained in the Communication Unit. Thus, two AS-i addresses are
assigned. AS-i concept of the Communication Unit

• 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

• Communication with the Lenze »Engineer« (access to all Lenze parameters) is executed via the
diagnostic interface of the Drive Unit.

•external Voltage supply

• a means for data transmission to and from the inverter.

( 23) of the Communication Unit;

 Note!

Only use cables that comply with the listed specifications.

Range Values

Cable type Two-wire cable, insulated and shielded

Core cross-section 1.5 mm

Cable resistance < 90 m/m, (f = 3 ... 20 MHz)

Inductance 400 ... 1300 nH/m

Capacitance per unit length < 80 pF/m

Electrical master value < 5 μS/m

Surge impedance 70 ... 140 

Group runtime < 8.3 ns/m

 Tip!

These data are also met by several other standardised cables. An AS-i network can also be
set up with different cables. Multi-core cables (e.g. DeviceNet Thick Cable, DESINA cable/
light conductor) or busbars can be used for the setup of AS-i networks, too. In case of doubt,
consult a specialist in the planning phase.

Prefabricated system cables can be obtained from diverse manufacturers.

Low-voltage supply via the AS-i-bus cable

In case of low-voltage supply via the AS-i bus cable, communication with the slaves is still possible
if no mains voltage is available.

• A previous mains connection (400 V) is not required.

• The digital inputs DI1 ... DI5, RFR and the analog input can still be evaluated.

• The AS-i input ports DI0 ... DI3 represent the digital inputs DI1 ... DI4 (see AS-i concept of the

Communication Unit ( 33)). The current status of these inputs can be called.

• All digital input and output data which can be selected by the inverter are deleted or invalid..
