Installation

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

1. Restore control power.
2. Connect field wiring via the DB9 plug. Example

Table 1: DB9 Connector

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.

Configuration

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.

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.

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.

 Data Structures

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 tem-perature.
• The parameter upload/download mode allows reading and writing soft starter parameter values.

Motor 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.

Soft Starter Programming I/O Data Structure
The soft starter programming I/O data structure allows uploading (reading) and downloading (writing) starter parameter values across the network.

NOTICE
Do not change the default values of the advanced parameters (parameter group 20-** Advanced Parameters). Changing these val-ues may cause unpredictable behavior in the soft starter.

Trip Codes

 PROFIBUS Diagnostic Telegram and Flag

1. Diagnostic Telegram Structure
   The PROFIBUS Card supports external diagnostics. The following telegram is sent to the Master if the soft starter trips or if a parameter is changed at the soft starter.

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, if the trip condition does not still exist (see 4.5 Trip Codes).

2. Changed Parameter Number
   If a parameter number 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.
   A changed parameter number does not set a diagnostic flag.

Supported Modes

1. PROFIBUS Freeze Mode
   In Freeze Mode, inputs are only updated with new data from the soft starter when another Freeze action is carried out. An unfreeze action returns the device to normal operation.

2. PROFIBUS Sync Mode
   In Sync Mode, commands to the soft starter are not processed until another sync action is carried out. An unsync action returns the device to normal operation.

3. PROFIBUS Clear Mode
   If the Master sends a global clear command, the device sends a quick stop command to the soft starter.
