130BT322.11Illustration 3.9 Enable Feature under DP Follower PropertiesNOTICEDP V1 diagnosis is supported for PROFIBUS SW version2.x and higher. The default setting of the PROFIBUSoption is DP V1 diagnosis. If DP V0 diagnosis is required,change the setting under DP follower Properties.Illustration 3.10 DP V1 DiagnosisDownload the configuration file to the PLC. The PROFIBUSsystem is able to go online, and it starts to exchange datawhen the PLC is set to Run mode.3.3 Configure the Frequency Converter3.3.1 Frequency Converter ParametersThe following parameters are important when configuringthe frequency converter with a PROFIBUS interface:• 0-40 [Hand on] Key on LCP. Pressing [Hand on]disables control of the frequency converter viaPROFIBUS.• Parameter 8-02 Control Word Source. After aninitial power-up, the frequency converterautomatically detects whether a fieldbus option isinstalled in slot A, and sets parameter 8-02 ControlWord Source to [Option A]. If an option is addedor changed in or removed from an alreadycommissioned frequency converter, it does notchange parameter 8-02 Control Word Source, butenters Trip mode, and the frequency converterdisplays an error.• Parameter 8-10 Control Word Profile. Selectbetween the Danfoss FC Profile and thePROFIdrive profile.• 8-50 Coasting Select to 8-56 Preset Reference Select.Select how to gate PROFIBUS control commandswith digital input command of the control card.• Parameter 8-03 Control Word Timeout Time to8-05 End-of-Timeout Function. Set the reaction inthe event of a bus time-out via these parameters.• 9-18 Node Address.• Parameter 8-07 Diagnosis Trigger.NOTICEWhen 8-01 Control Site is set to , the settings in8-50 Coasting Select to 8-56 Preset Reference Select areoverruled, and all act on Bus-control.3.3.2 LEDsThe 2 bi-colour LEDs in the PROFIBUS card indicate thestatus of PROFIBUS communication.The LED marked NS (FCD 302: NS2) indicates the networkstatus, that is, the cyclical communication to the PROFIBUSmaster. When this light is constant green, data exchangebetween the master and the frequency converter is active.The LED marked MS (FCD 302: BUS MS) indicates themodule status, that is, acyclical DP V1 communication fromeither a PROFIBUS master class 1 (PLC) or a master class 2(MCT 10, FDT tool). When this light is constant green, DPV1 communication from master classes 1 and 2 is active.For details of the full range of communications statusindicated by the LEDs, refer to chapter 8 Troubleshooting.Configuration Programming GuideMG37G102 Danfoss A/S © Rev. 05/2014 All rights reserved. 113 3
