1. Remove control power and mains supply from the soft
starter.
2. Disconnect all field wiring from the module.
3. Fully pull out the top and bottom retaining clips on the
module.
4. Pull the module away from the soft starter.
Installation Instruction: MCD Profibus Module
Order Code: 175G9001
1. Important User Information

It is the installer's responsibility to follow all instructions in this manual and to follow correct
electrical practice.
2. Installation
1. Remove control power and mains supply from the soft starter.
2. Attach the module to the soft starter as illustrated.
3. Set the module address to match the address set in the Master configuration tool.
4. Apply control power to the soft starter.
5. Insert the network connector and power up the module.
2.2. Physical Installation
1. Fully pull out the top and bottom retaining clips on the module.
2. Line up the module with the comms port slot.
3. Push in the top and bottom retaining clips to secure the module to the starter.

Configuration MCD Profibus Module Instructions
N.B.!:
The Profibus Module has a slave address range of 0 to 99.
N.B.!:
If the Communication Timeout parameter is set to 0, the current state of the soft
starter will remain unchanged on a network failure. This gives the user the option of
operating the soft starter via local control, but is NOT failsafe.
3. Configuration
Import the latest .gsd file into your Master configuration tool. This file is available from
www.danfoss.com/drives.
If your Master uses on-screen icons, two graphic bitmap files are available from the website.
SSPM_N.bmp indicates normal mode. SSPM_D.bmp indicates diagnostic mode.
If the Profibus network fails, the module will leave 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 will be forced into a trip state.
The user can adjust the Communication Timeout parameter in the GSD file to any setting
between 0 and 100 seconds. The default setting is 10 seconds.
4. Adjustment
Before powering up the Profibus Module, set the two rotary switches so that the module address
matches the address set in your Master configuration tool (the diagram shows the factory default
setting for the rotary switches).
The module automatically detects the network data rate.

is set to Disable Comms in Remote, the
starter will not accept start or stop commands from the serial network (the starter will
still accept reset commands and allow status monitoring).
5. Connection
The module connects to the Profibus network via a standard 9-pin Sub-D connector.
The Profibus Module can be powered either through the network cable or externally (24 VDC).
MCD 200: For the Profibus Module to accept serial commands, a link must be fitted across
terminals A1-N2 on the soft starter.
In order for the MCD 500 to accept commands from the serial network, the soft starter must be in
Auto On mode and links must be fitted to terminals 17, 18 and 25, 18.
In Hand On mode, the starter will not accept commands from the serial network but the starter's
status can still be monitored.

7. Data Structures
The GSD file contains three operating modules, supporting data I/O structures as follows:
The Basic Module allows the user to start and stop the soft starter and read limited information on
operating status.
The Extended Module defines additional bytes allowing the user to read soft starter operating
data such as actual motor current and motor temperature.
The Parameter Upload/Download Module allows the user to read and write soft starter parameter
values (only applicable to MCD 500 soft starters).

percentage, divide by 0.315.
Ready is set when the soft starter is ready to start the motor.
On is set when the soft starter is starting, running or soft stopping the motor.
Warning is set when the soft starter detects a warning condition.
Fault is set when the soft starter has tripped.
Ramping is set when the soft starter is starting or soft stopping the motor.
Hand On is set when the soft starter is set to Hand On mode.

11. Profibus Diagnostic Telegram and Flag
The Profibus Module supports external diagnostics. The following telegram will be sent to the
Master if the soft starter trips or if a parameter is changed at the soft starter.
11.1. Profibus Trip Code
When the soft starter trips, a diagnostic flag is set at the Master and the trip code is reported in
Byte 1. When the soft starter is reset, the diagnostic flag and trip code data are reset = 0,
provided the trip condition does not still exist (see
page 6 for trip codes).
11.2. Changed Parameter Number
If a parameter is changed via the LCP, the affected parameter number is reported in Byte 2.
When the Master reads or writes the changed parameter, Byte 2 is reset = 0.
Soft Starter Monitoring I/O Data Structure

A changed parameter number does not set a diagnostic flag.
12. Profibus Freeze Mode
The Profibus Module supports Freeze Mode.
In Freeze Mode, inputs are only updated with new data from the soft starter when another Freeze
action is carried out. An Un-Freeze action returns the Profibus Module to normal operation.
13. Profibus Sync Mode
The Profibus Module supports Sync Mode.
In Sync Mode, commands to the soft starter are not processed until another Sync action is carried
out. An Un-Sync action returns the Profibus Module to normal operation.
14. Profibus Clear Mode
If the Master sends a global Clear command, the Profibus Module will send a Quick Stop
command to the soft starter.
