The VACON® RS485 and CAN Bus Option Boards are designed for safe installation and commissioning with VACON® AC drives. This installation guide provides comprehensive information for various option boards, including RS485 serial bus-based boards (OPTE3/E5 PROFIBUS, OPTC3/C5 PROFIBUS, OPTE2/E8 RS485, OPTC2/C8 Modbus, OPTCJ BACnet) and CAN bus-based and other option boards (OPTE6 CANopen, OPTE7 DeviceNet, OPTC6 CANopen, OPTC7 DeviceNet, OPTC4 LONworks). The manual is intended for qualified personnel familiar with the VACON® drive series, emphasizing adherence to safety instructions.

Function Description

These option boards extend the communication capabilities of VACON® AC drives, enabling them to interface with various fieldbus protocols. The RS485-based boards facilitate serial communication using protocols like PROFIBUS DP, Modbus RTU, Metasys N2, and BACnet MSTP. The CAN bus-based boards support CANopen and DeviceNet protocols, while the OPTC4 board is designed for LONworks networks. Each board is compatible with specific VACON® AC drive series, including NXP, NXS, 100 INDUSTRIAL, 100X, 100 FLOW, 100 HVAC, 20, 20 X, and 20 CP. The installation process involves opening the AC drive cover, removing cable covers or grounding brackets as needed, installing the option board into designated slots (D or E), and then connecting and grounding the fieldbus cables. For VACON® 20 drives, a separate option board mounting kit is required.

Important Technical Specifications

- OPTC2/C8 Modbus/N2: Compatible with VACON® NXP, NXS. Uses slots D, E. Supports Modbus RTU, Metasys N2.
- OPTCJ BACnet: Compatible with VACON® NXP, NXS. Uses slots D, E. Supports BACnet MSTP.
- RS485 Cable Requirements: Shielded cables with twisted-pair signal wires. Recommended minimum distance from motor cables is 300 mm. Maximum cable length depends on baud rate (e.g., 1200m for 9.6 kbit/s, 100m for 3000-12000 kbit/s). Bus termination and bias resistors are crucial for faultless communication, with internal resistances of 120 Ω and 560 Ω respectively. External termination and biasing can be added based on the number of nodes and cable length.

- OPTE7 DeviceNet: Compatible with VACON® NXP, 100 INDUSTRIAL, 100X, 100 FLOW, 20, 20X, 20CP. Uses slots D, E. Supports DeviceNet.
- OPTC7 DeviceNet: Compatible with VACON® NXP, NXS. Uses slots D, E. Supports DeviceNet.
- OPTC4 LonWorks: Compatible with VACON® NXP, NXS, 100 INDUSTRIAL, 100X, 100 FLOW. Uses slots D, E. Supports LonWorks.
- CAN Type Cable Requirements: Four-wire twisted and shielded cables with an impedance of 120 Ω. Termination resistance of ~120 Ω (or 150-300 Ω for long networks). Minimum cable length of 1 meter between stations. Maximum bit rate and cable resistance vary with cable length (e.g., 1000 kbit/s for 0-40m, 50 kbit/s for 1000m).
- LON Type Cable Requirements: Up to 64 FTT-10 transceiver nodes per network segment. Shielded cables are highly recommended. Minimum cable length of 1 meter between stations. Recommended cable types include Belden 85102, Belden 8471 LONAK, Level IV 22 AWG LONAK, and JY (St) Y 2 x 2 x 0.8 mm LONAK. Maximum bus length and free topology wire length vary by cable type.

Usage Features

The option boards allow VACON® AC drives to integrate seamlessly into various industrial control networks. Users can select the appropriate board based on the required fieldbus protocol and drive compatibility. The installation process is detailed with illustrations for different drive models (VACON® NXP/NXS, 100 INDUSTRIAL/FLOW, 100 X, 20, 20 X/20 CP). Jumpers on the boards enable configuration of bus termination, cable shield grounding, and other protocol-specific settings. The manual provides clear instructions for setting these jumpers to ensure proper network operation. For D9 connectors, a separate grounding cable is used to achieve 360° grounding, enhancing electromagnetic compatibility.

Maintenance Features

The manual includes a comprehensive troubleshooting section with LED indications for each option board. These LEDs provide visual feedback on the board's status, protocol communication, and potential faults.
