INSTALLATION INSTRUCTIONS:
MCD DEVICENET MODULE
Order Code: 175G9002
Important User Information
Observe all necessary safety precautions when controlling the soft starter remotely. Alert personnel that machinery may start without warning.
It is the installer’s responsibility to follow all instructions in this manual and to follow correct electrical practice.
Installation
CAUTION
Remove mains and control voltage from the soft starter before attaching or removing accessories. Failure to do so may damage the equipment.
Install the Device Net Module using the following procedure:
- Remove control power and mains supply from the soft starter.
- Attach the module to the soft starter as illustrated.
- Set the Device Net Module Node Address (MAC ID) and Data Rate.
- Apply control power to the soft starter.
- Insert the network connector into the module and power up the Device Net network.
2.1. Physical Installation
- Fully pull out the top and bottom retaining clips on the module.
- Line up the module with the comms port slot.
- Push in the top and bottom retaining clips to secure the module to the starter.
Remove the module using the following procedure:
- Take the module off-line.
- Remove the Device Net connector.
- Remove control power and mains supply from the soft starter.
- Fully pull out the top and bottom retaining clips on the module.
- Pull the module away from the soft starter.
CAUTION
Network designs must decrease the maximum allowable cumulative dropline length by 400 mm for every module installed on the network. Failure to do so may result in network communication errors and decreased reliability.
Example: ODVA specifies a maximum cumulative dropline length of 156 m on a network operating at 125 kb/s. If six modules were installed on this network, the total cumulative dropline length would need to be decreased to 153.6 m.
Configuration
The Device Net Module is a Group 2 slave device, using a predefined master/slave connection set.
I/O data is produced and consumed using polled I/O messaging.
The soft starter must be added to the Device Net manager project using the EDS file and configuration/management software tool. This file is available from www.danfoss.com/drives. In order to operate successfully, the correct EDS file must be used. An on-screen graphics bitmap file (device.bmp) is also available.
Adjustment
The factory default settings for the rotary adjustment switches are:
Changes to the rotary switch settings take effect when the Device Net network is next powered up.
N.B.!:
The Data Rate and Node Address (MAC ID) must be set locally on the module.
These cannot be set using DeviceNet management software.
When the Data Rate and MSD Node Address (MAC ID) rotary switches are set on PGM position, the module uses the previously used valid on-line Data Rate and Node Address (MAC ID).
Connection
MCD 200: For the MCD Device Net 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.
| 1 | MCD 200 | 1 | MCD 500 (Auto On mode) 17, 18: Stop 25, 18: Reset |
| 2 | MCD Device Net Module | 2 | MCD Device Net Module |
| 3 | Standard connection onto Device Net network | 3 | Standard connection onto Device Net network |
N.B.!:
If MCD 500 parameter 3-2 Comms in Remote 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).
Module and Network LEDs
The Module LED indicates the condition of the power supply and module operation.
The Network LED indicates status of the communication link between the Device Net Module and the network Master.
| LED | State | Description |
|
(1)(Module) |
Off | Network power off |
| Green | Normal operation | |
| Red | Unrecoverable fault | |
| Red/Green flashing | Self Test mode | |
|
(2)(Network) |
Off | Duplicate MAC ID test has not been completed |
| Green flashing | Online but no connection with Master | |
| Green | Online and allocated to a Master | |
| Red flashing | One or more timed out I/O connections | |
| Red | Failed communication between module and Master | |
| Red/Green flashing | Communication faulted and received an Identity communication faulted request |
N.B.!:
When a communications failure occurs, the soft starter may trip if the Communication Timeout parameter for the network is set greater than zero. When communication is restored, the soft starter must be reset.
Device Net Polled I/O Structure
Once the EDS file has been loaded, the Device Net Module must be added to the scanner list with parameters shown in the following table:
| Parameter | Value |
| I/O connection type | Polled |
| Poll receive size | 14 bytes |
| Poll transmit size | 2 bytes |
Once the soft starter, module and Master have been set up, configured and powered up, the Master will transmit 2 bytes of data to the module and receive 14 bytes of data from the module.
Master > Slave polled I/O output data is as follows:
| Byte | Bit | Function |
| 0 | 0 | 0 = Stop command 1 = Start command |
| 1 | 0 = Enable Start or Stop command 1 = Quick Stop (i.e. coast to stop) and disable Start command |
|
