Product Overview
RCAN-01 is an ABB CANopen adapter module for drive option slots. It adds CANopen connectivity to ABB drives. Node address and baud rate set through rotary switches. The module draws up to 250 mA at 5 V from the drive control board. It supports transfer rates from 10 kbit/s to 1 Mbit/s. The network handles up to 128 nodes in multi-drop topology. Materials meet UL/CSA approval. EMC compliance covers EN 50081-2 and EN 50082-2. Engineers use it for fieldbus control in compact panels.

FAQ
Q: How do I set the node address on the RCAN-01?
A: Use the rotary switches on the module. Range is 00 to 99. Set the address before power-up. Match it to your network master configuration.
Q: Which baud rate should I pick for a 100 m network?
A: At 100 m, 500 kbit/s or 250 kbit/s works well. Higher rates like 1 Mbit/s suit shorter drops. Lower rates extend reach. Balance speed against cable length.
Q: Does the module need external 5 V power?
A: No. The drive control board supplies up to 250 mA at 5 V. Do not add a separate 5 V feed. Check the drive manual for slot current limits.
Q: What termination resistor does the CANopen bus need?
A: Use 121 ohm, 1%, metal film, 1/4 W at both bus ends. This matches the module spec. Wrong termination causes signal reflection and node errors.
Q: Can I use the RCAN-01 in a retrofit?
A: Yes, if your ABB drive has a compatible option slot. Confirm firmware supports CANopen. Check the 34-pin bus and 9-pin DSUB clearance. Share your drive model for cross-check.
Q: What is the warranty and shipping lead time?
A: Every RCAN-01 comes with a 12-month warranty. In-stock items ship in 24–28 hours via FedEx, UPS, DHL. Email info@oiltechcontrols.com or message +86 158 8020 0923 on WhatsApp.
