Initiators can be directly connected to the digital inputs of the frequency inverter. Actuators can be
connected via the available digital outputs of the device. The following connections are each provided
for four reference data bits:

Bits 2 and 3 are directly coupled to digital inputs 1 and 2
Parallel actuation via the BUS and the digital inputs is possible. The relevant inputs are dealt with
more or less as normal digital inputs. If a changeover between manual and automatic is going to take
place, it must be ensured that no enable via the normal digital inputs takes place in automatic mode.
This could be implemented e.g. with a three-position key switch. Position 1: "Manual left" Position 2:
"Automatic" Position 3: "Manual right".
If an enable is present via one of the two "normal" digital inputs, the control bits from the bus system
are ignored. An exception is the control bit "Acknowledge fault". This function is always possible in
parallel, regardless of the control hierarchy. The bus master can therefore only take over control if no
actuation via a digital input takes place. If "Enable left" and "Enable right" are set simultaneously, the
enable is removed and the motor stops without a deceleration ramp (block voltage).
4.5.4.4 Addressing
In order to use the device in an AS-i network, it must have a unique address. The address is set to 0 in
the factory. This means that the device can be recognised as a "new device" by an AS-i master
(prerequisite for automatic address assignment by the master).
Course of action
• Ensure power supply of the AS interface via the yellow AS interface cable.
• Disconnect the AS interface master during addressing
•
Set the address ≠ 0
• Do not doubly assign addresses
In many other cases, addressing is carried out using a normal addressing device for AS interface
slaves (example follows).
• Fuchs, VBP-HH1-V3.0-V1 (separate M12 connection for external power supply)
• IFM, AC1154 (battery operated addressing device)
