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. 4 | Danfoss A/S © 2018.10 AQ277154312778en-000102 / 175R1180 Installation Guide | Modbus RTU Card Installation 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: 1 2 e77ha739.10 Illustration 1: Installation of the Expansion Cards 2.2 Connecting to the Network Prerequisites: The expansion card must be installed in the soft starter. Procedure 1. Restore control power. 2. Connect field wiring via the 5-way connector plug.

For successful operation, the client must also support all functions and interfaces described in this manual. 3.2 Master Configuration For standard Modbus 11-bit transmission, configure the master for 2 stop bits with no parity and 1 stop bit for odd or even parity. For 10-bit transmission, configure the master for 1 stop bit. In all cases, the master baud rate and slave address must match those set in parameters 12-1 to 12-4. The data polling interval must be long enough for the module to respond. Short polling intervals may cause inconsistent or incorrect behavior, particularly when reading multiple registers. The recommended minimum polling interval is 300 ms. 3.3 Configuration 3.3.1 Modbus Network Settings Set the network communication parameters for the card via the soft starter. For details on how to configure the soft starter, see the VLT® Soft Starter MCD 600 Operating Guide. Table 1: Parameter Settings Parameter 12-1 12-2 12-3 12-4 Parameter name Modbus Address Modbus Baud Rate Modbus Parity Modbus Timeout Description Sets the Modbus RTU network address for the soft starter. Selects the baud rate for Modbus RTU communications. Selects the parity for Modbus RTU communications. Selects the timeout for Modbus RTU communications. NOTICE The Modbus RTU Card reads communications parameter settings 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. 3.3.2 Enabling Network Control The soft starter only accepts commands from the expansion 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. Danfoss A/S © 2018.10 AQ277154312778en-000102 / 175R1180 | 7 Installation Guide | Modbus RTU Card Operation 3.4 Feedback LEDs LED status Off On Flashing Description The soft starter is not powered up. Communication active. Communication inactive. 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. 8 | Danfoss A/S © 2018.10 AQ277154312778en-000102 / 175R1180 Installation Guide | Modbus RTU Card 4 Modbus Registers 4.1 PLC Configuration Use the tables in 4.5 Standard Mode to map registers within the device to addresses within the PLC. NOTICE All references to registers mean the registers within the device unless otherwise stated. Modbus Registers 4.2 Compatibility The Modbus RTU Card supports 2 modes of operation: · In Standard Mode, the device uses registers defined in the Modbus Protocol Specification. · In Legacy Mode, the device uses the same registers as the clip-on Modbus Module supplied by Danfoss for use with older soft starters. Some registers differ from those specified in the Modbus Protocol Specification. 4.3 Ensuring Safe and Successful Control Data written to the device remains in its registers until the data is overwritten or the device is reinitialized. If the soft starter should be controlled via parameter 7-1 Command Override or should be disabled via the reset input (terminals RESET, COM+), fieldbus commands should be cleared from the registers. If a command is not cleared, it is resent to the soft starter once fieldbus control resumes. 4.4 Parameter Management Parameters can be read from and written to the soft starter.The Modbus RTU can read or write a maximum of 125 registers in 1 operation. NOTICE The total number of parameters in the soft starter may vary according to the model and parameter list of the soft starter. Attempting to write to a register not associated with a parameter returns an error code 02 (illegal data address). Read register 30602 to determine the total number of parameters in the soft starter. NOTICE Do not change the default values of the Advanced parameters (parameter group 20-** Advanced Parameters). Changing these values may cause unpredictable behavior in the soft starter.
