5.4.4 Commissioning of the AS Interface
Connection
Connection of the AS interface cable is made via terminals 85/85 of the terminal block and can optionally be
made to an appropriately labelled M12 flange plug contact (yellow) Details of the connection terminals are
explained in Section 2.8.2.
Signal status LED / ASi-specific display
With these devices, the status of the ASi interface is indicated by the dual colour LEDAS-i.
LED (dual) Meaning
OFF No AS interface voltage to the module (PWR)
Connections to terminals 84 and 85 exchanged.
green ON Normal operation (AS interface active)
red ON no exchange of data
 Slave address = 0
 Slave not in LPS
 Slave with incorrect IO/ID
 Master in STOP mode
 Reset active
alternately
flashing
red / green Peripheral error
 FI control unit does not start (AS-i voltage too low,
control unit faulty)
Control voltage - frequency inverter supply
The yellow ASi cable supplies the AS interface with the necessary control voltage. The control section of the
frequency inverter is not supplied from the AS interface voltage.
Configuration
The most important functions are assigned via the arrays [- 01] … [-04] of parameter (P480) and (P481).
Addressing
In order to use a frequency inverter in an ASi network, this must be assigned with a unique address (1-31).
The FI is set to address 1 as the factory setting, and can therefore be identified as a "new device" by the
AS-i master (prerequisite for the automatic address assignment by the master).
In many other cases, addressing is carried out by means of a normal addressing device for AS-i slaves.
The following should be noted:
