The data rate for Interbus-S is fixed at 500 Kbits/sec. Interbus-S networks are "centralised" systems, requiring a master controller (usually a PLC) which controls all communications with slave nodes on the network. The Interbus-S Interface for Unidrive is a slave node only.   Key Features - Supplied as the large option module and fits easily under the Unidrive Keypad. - Fully conformant   - Full co-processor functionality is retained - Supports 2-wire Interbus-S networks at a fixed data rate of 500 Kbits/sec. - Supports three 16 bit cyclic data channels - Two cyclic data channels can be combined to produce a single 32 bit cyclic data channel, allowingcomplete access to all co-processor Position Controller parameters via the Interbus-S network. - Full cyclic data channel mapping allows any cyclic data channel to control or source from anysuitable drive and co-processor parameters. - Default mappings - * Speed/frequency feedback * Torque feedback * Status word provides status bits about 15 drive functions, eg drive healthy, drive running, at speed etc. * Speed/frequency reference * Torque feedback reference * Control word allows ENABLE, RUN and DIRECTION signals, plus reference selection and user bit parameters to be transmitted in one cyclic data word - Network Loss detection will trip the drive (if enabled) when the network connection is lost. - Local network diagnostics - "Peer - Peer" or "Slave to Master" communications are not supported.   Specifications Network - RS485 optically-isolated physical layer - Data rates fixed at 500 Kbits/sec - Up to 400m cable length between nodes - Up to 32 Unidrive slave nodes on a single network - Interbus-S ID Code: 0xF3 - Interbus-S Specification refer to www.interbusclub.com   Environment - Ambient Temperature: -5ºC to +40ºC - Storage Temperature: -40ºC to +50ºC - Weight: 196g - Maximum Altitude: 1000 m - Humidity: +5% to +95% at 40ºC non-condensing
