5.3 Setting-up AS-i parameters
Setting-up AS-i parameters
Setting the AS-i parameters
Once the inverter has been installed and assigned an appropriate address the Inverter is
ready to be commissioned.
Once the Inverter is switched on, the Inverter should be automatically recognized by the AS-i
The status LEDs on the Inverter will indicated the status of the AS-i communications with
regard to the Inverter.
The following parameters must be set to configure the AS-i communications of the Inverter.

CTT2 data to AS-i master (see note below)
AS-i master digital input for slave
* For further details, please refer to the parameter manual
Parameters settings directly affecting the AS-i communications, for example, P2040 will not
take effect until the Inverter has been restarted by a cold restart. This cold restart must be
initiated by switching the power off and then on again.
Combined Transaction Type 2 (CTT2) is intended for simple and complex field devices such
as temperature sensors, displays with more than eight characters, speed controlled motors
with actual value feedback, analog process valves with position feedback or similar field
devices in which digital data needs to be sent in both directions. Data exchange is full-
duplex, that is, both binary data as well as digital input and output data can be sent at the
same time. No special switching of the data transfer direction is required.
