SK 190E 84 85 - 1) - 1)
1) The control unit of the frequency inverter is not supplied from the AS-I line. The auxiliary voltage that is required for this is generated by
the device itself.
Table 11: AS Interface, connection of signal and supply lines
If the AS interface ("yellow cable") is not used, the normal connection requirements for the device
apply (

Section 2.4.3 "Electrical connection of the control unit").
4.5.4.2 Displays
The status of the AS interface is signalled by a multi-
colour AS-i LED.
AS-i LED Meaning
OFF • No AS interface voltage to the module
• Connections not connected or exchanged
green ON • Normal operation (AS interface active)
red ON • No exchange of data
– Slave address = 0 (slave still in factory setting)
– Slave not in LPS (list of planned slaves)
– Slave with incorrect IO/ID
– Master in STOP mode
– Reset active

• Peripheral error
– Control unit in device not starting
(AS-i voltage too low or control unit defective)
4.5.4.3 Configuration
The most important functionality is assigned via the arrays [-01] … [-04] of parameters (P480) and
(P481).
Bus I/O bits
WARNING Unexpected movement due to automatic starting
In the event of a fault (communication interrupted or bus cable disconnection, the device automatically switches
off, since the device enable is no longer present.
Restoration of communication may result in an automatic start and therefore, unexpected movement of the drive
unit. To prevent any hazard, a possible automatic start must be prevented as follows:
• If a communication error occurs, the bus master must actively set the control bits to "zero".
