DeviceNet Slave Communication Module IFD9502 z Format of messages responded z Note When modifying parameters in the parameter table of Delta ASD-A servo drive, make sure that the parameter allows you to modify it before you modify it. 3. I/O data mapping (Default) z Servo drive → DeviceNet master z DeviceNet Master → Servo drive z Explanation: „ When the equipment connected to IFD9502 is a servo drive, the length of data downloaded from IFD9502 to the servo drive is preset as 1 word at addresses H’0407 (corresponding address of DI1 ~ DI8). IFD9502 is able to download maximum 16 words.
The length of data uploaded to IFD9502 from the servo drive is preset as 1 word at addresses H’0409 (corresponding address of DO1 ~ DO5). IFD9502 is able to be uploaded maximum 16 „ The length of I/O data to be exchanged and address for mapping can be modified through words. changing Class9B s listed below. The modification will be valid after IFD9502 is re-powered. Maximum 32 words are allowed for I/O data exchange. „ If you are to return the I/O mapping to default setting, change Attribute1 of Instance1 of Class 0x9B into H’0001 and re-power IFD9502. Please note that doing so can only recover the current I/O data mapping in servo drive. „ Class 0x9B Data Config Instance0: Instance1:
