3 Configuration

3.1 Preparations

Import the latest .gsd file in the Master configuration tool. This file is available from the supplier at www.danfoss.com/en/service-and-
support/downloads/dds/fieldbus-configuration-files/#tab-downloads.
If the Master uses on-screen icons, 2 graphic bitmap files are available from the website. SSPM_N.bmp indicates normal mode.
SSPM_D.bmp indicates diagnostic mode.

3.2 PROFIBUS Address

Set the network address for the card via the soft starter (parameter 12-7 PROFIBUS Address). For details on how to configure the soft
starter, see the VLT® Soft Starter MCD 600 Operating Guide.
The PROFIBUS Card reads the network address from the soft starter when control power is applied. If parameters are changed
in the soft starter, cycle control power for the new values to take effect.

3.3 Enabling Network Control

The soft starter only accepts commands from the PROFIBUS Card if parameter 1-1 Command Source is set to Network.
If the reset input is active, the soft starter does not operate. If a reset switch is not required, fit a link across terminals RESET,
COM+ on the soft starter.
If the PROFIBUS network fails, the device leaves data exchange mode after the network watchdog timeout period has expired. This
timeout period is set at the Master configuration tool.
A Communication Timeout parameter in the GSD file sets how soon after this event the soft starter is forced into a trip state.
Adjust the Communication Timeout parameter in the GSD file to any setting from 0–100 s. The default setting is 10 s.
If the Communication Timeout parameter is set to 0, the current state of the soft starter remains unchanged on a network
failure. This gives the option of operating the soft starter via local control, but is NOT failsafe.
