4 How to Configure

4.1.1 IP Settings

All IP-related parameters are located in parameter group
12-0* IP Settings: The parameters are all set to EtherCAT
standard values, so no setting is needed.
The EtherCAT option offers several ways of IP address
assignment.

4.1.2 EtherNet Link Parameters

Parameter group 12-1* holds EtherNet Link information:
12-10 Link Status
12-11 Link Duration
12-12 Auto Negotiation
12-13 Link Speed
12-14 Link Duplex
Each port has unique EtherNet Link Parameters.
12-10 Link Status and 12-11 Link Duration displays
information on the link status, per port.
12-10 Link Status displays Link or No Link according to the
status of the present port.
12-11 Link Duration displays the duration of the link on the
present port. If the link is broken, the counter is reset.
12-12 Auto Negotiation is a feature that enables two
connected EtherNet devices to choose common
transmission parameters, such as speed and duplex mode.
In this process, the connected devices first share their
capabilities and then choose the fastest transmission mode
they both support.
Incapability between the connected devices could lead to
decreased communication performance.
To prevent this, Auto Negotiation can be disabled.
If 12-12 Auto Negotiation is set to OFF, link speed and
duplex mode can be configured manually in 12-13 Link
Speed and 12-12 Auto Negotiation.
12-13 Link Speed - displays/sets the link speed for each
port. If no link is present, "None" is displayed.
12-14 Link Duplex - displays/sets the duplex mode for each
port.
Half-duplex provides communication in both directions,
but only in one direction at a time (not simultaneously).
Full-duplex allows for simultaneous communication in both
directions.

4.2 Configure the Frequency Converter

4.2.1 VLT Parameters

Pay particular attention to the following parameters when
configuring the frequency converter with an EtherCAT
interface.
NOTE
When 8-01 Control Site is set to [2] Control word only, the
settings in 8-50 Coasting Select to 8-56 Preset Reference
Select are overruled, and all act on Bus-control.

•
0-40 [Hand on] Key on LCP. If the [Hand on] key
on the frequency converter is activated, control of
the frequency converter via the EtherCAT
interface is disabled.
•
After an initial power up, the frequency converter
automatically detects whether a fieldbus option is
installed in slot A, and set 8-02 Control Word
Source to [Option A]. Adding, changing, or
removing an option from an already commis-
sioned frequency converter, does not change
8-02 Control Word Source. However, it causes a
Trip Mode, and the frequency converter displays
an error.
•
8-10 Control Word Profile. Choose between the
Danfoss FC Profile and the DS 402 profile.
•
8-50 Coasting Select to 8-56 Preset Reference Select.
Selection of how to gate EtherCAT control
commands with digital input command of the
control card.
•
8-03 Control Word Timeout Time to 8-05 End-of-
Timeout Function. The reaction in the event of a
bus time-out is set via these parameters.
