1 Safety
1.1 Disclaimer
The examples and diagrams in this manual are included solely for illustrative purposes. The information contained in this manual is
subject to change at any time and without prior notice. Responsibility or liability is never accepted for direct, indirect, or consequential
damage resulting from the use or application of this equipment.
1.2 Warnings
WARNING
SHOCK HAZARD
Attaching or removing accessories while the soft starter is connected to mains voltage may cause personal injury.
-Before attaching or removing accessories, isolate the soft starter from mains voltage.
WARNING
RISK OF PERSONAL INJURY AND EQUIPMENT DAMAGE
Inserting foreign objects or touching the inside of the soft starter while the expansion port cover is open may endanger
personnel and can damage the soft starter.
-Do not insert foreign objects in the soft starter with the port cover open.
-Do not touch the inside of the soft starter with the port cover open.
1.3 Important User Information
Observe all necessary safety precautions when controlling the soft starter remotely. Alert personnel that machinery may start without
warning.
The installer is responsible for following all instructions in this manual and for following correct electrical practice.
Use all internationally recognized standard practice for RS485 communication when installing and using this equipment.

2 Installation
2.1 Installing the Expansion Card
Procedure
1. Push a small flat-bladed screwdriver into the slot in the center of the expansion port cover and ease the cover away from the soft
starter.
2. Line up the card with the expansion port.
3. Gently push the card along the guide rails until it clicks into the soft starter.
Example:

2.3 Feedback LEDs
Off On
Power (red) Device is not powered up. Device is powered up and ready to go online.
Network (green) No connection, offline or data exchange failure. Device is online and in data exchange state.
NOTICE
If communication is inactive, the soft starter may trip on Network Communications. If parameter 6-13 Network Communications is
set to Soft Trip and Log or Trip Starter, the soft starter requires a reset.
NOTICE
If communication fails between the device and the network, the Bus Status LED goes off. When communication is restored, the
Bus Status LED turns back on.

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.
NOTICE
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.
NOTICE
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.
NOTICE
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.

4 Data Structures
4.1 Operating Modes
The GSD file contains 3 operating modes, supporting data I/O structures as follows:
Data structure Basic mode Extended mode Parameter upload/download mode
Soft Starter Control I/O Data Structure ✓ ✓ ✓
Soft Starter Monitoring I/O Data Structure ✗ ✓ ✓
Soft Starter Programming I/O Data Structure ✗ ✗ ✓
The basic mode allows starting and stopping the soft starter and reading limited information on operating status.
The extended mode defines more bytes allowing to read soft starter operating data such as actual motor current and motor
temperature.
The parameter upload/download mode allows reading and writing soft starter parameter values.
4.2 Soft Starter Control I/O Data Structure
Table 2: Master/Slave Control Word Structure
Byte Bits Details
0 0–1 Reserved
2–3 0=Use soft starter remote input to select motor set
1=Use primary motor set when starting
2=Use secondary motor set when starting
4=Reserved
4 0=Stop action is a soft stop (as selected on the soft starter)
1=Stop action is a quick stop (coast to stop)
5–7 Reserved
1 0 0=Stop
1=Start
1–2 Reserved
3 1=Reset
4–7 Reserved
NOTICE
Bit 4 of byte 0 must be set to 0 for the soft starter to start.

1 0 1=Ready
1 1=Starting, running, or stopping
2 1=Tripped
3 1=Warning
4–7 Reserved
1Motor current (%FLC) shows current as a percentage of the set motor full load current. A value of 63 represents 200% full load current. To convert this value to a readable percentage,
divide by 0.315. For models MCD6-0063B and smaller, this value is 10 times greater than the value shown on the LCP.
