<\/figure>\n\n\n\nStep 1: Configure the CAN Control Mode<\/h2>\n\n\n\n
The first essential setting is the servo control mode.<\/p>\n\n\n\n Set Pn006.0 = 1 to configure the ED3L servo for CAN bus control.<\/p>\n\n\n\n This allows the servo drive to receive commands through the communication network.<\/p>\n\n\n\n If communication fails, the servo may display Alarm A.66.<\/p>\n\n\n\n The manual also lists Pn001 for restoring factory defaults. However, a factory reset should only be performed when necessary because it may erase existing machine-specific settings.<\/p>\n\n\n\n The baud rate determines the communication speed between the controller and servo drives.<\/p>\n\n\n\n For ED3L configuration, the manual specifies:<\/p>\n\n\n\n Set Pn703 = 4.<\/p>\n\n\n\n The E315P uses a predefined internal communication rate, so the servo configuration must match the controller’s requirements.<\/p>\n\n\n\n Incorrect baud rate settings may prevent successful communication.<\/p>\n\n\n\n When checking ESTUN E315P CAN Communication, confirm this parameter before changing other servo settings.<\/p>\n\n\n\n Each servo drive requires a unique CAN Node ID.<\/p>\n\n\n\n The corresponding parameter is:<\/p>\n\n\n\n Pn704.0 \u2014 Servo CAN Node ID<\/p>\n\n\n\n The Node ID must match the axis assignment configured in the E315P Machine Parameters.<\/p>\n\n\n\n Par exemple:<\/p>\n\n\n\n Controller Axis Node ID = 1 \u2192 Servo Node ID = 1<\/p>\n\n\n\n When configuring multiple servo drives, confirm that:<\/p>\n\n\n\n Incorrect or duplicated addresses can cause communication problems or prevent the controller from identifying the intended axis.<\/p>\n\n\n\n The ED3L servo provides separate settings for positive and negative limit detection.<\/p>\n\n\n\n Pn000.1 controls positive limit detection, while Pn000.2 controls negative limit detection.<\/p>\n\n\n\n These settings must match the actual machine wiring.<\/p>\n\n\n\n If physical limit switches are installed, the corresponding detection functions should remain enabled.<\/p>\n\n\n\n Do not disable an installed limit switch merely to clear an alarm. Check the wiring and safety conditions before modifying these parameters.<\/p>\n\n\n\n The E315P manual identifies the following ED3L parameter:<\/p>\n\n\n\n This parameter is associated with the datum reference switch.<\/p>\n\n\n\n For the specified configuration, connect the reference switch to 1CN Port, Pin 15 on the servo drive.<\/p>\n\n\n\n The home signal is assigned to Port 15 in the applicable CANopen configuration.<\/p>\n\n\n\n If datum referencing is not required, retain the factory settings.<\/p>\n\n\n\n Correct datum configuration helps ensure that the servo system recognizes the intended reference signal.<\/p>\n\n\n\n After completing the configuration, verify the essential parameters.<\/p>\n\n\n\n Check the CAN communication connections against the electrical diagram.<\/p>\n\n\n\n Confirm that the controller recognizes the connected servo drives and that no communication alarms are present.<\/p>\n\n\n\n Follow the servo manufacturer’s instructions for applying parameter changes before testing axis movement.<\/p>\n\n\n\n If ESTUN E315P CAN Communication fails, inspect the configuration systematically.<\/p>\n\n\n\n First, confirm that the servo is operating in CAN bus control mode.<\/p>\n\n\n\n Next, check the baud rate and verify that each servo Node ID matches the corresponding controller axis.<\/p>\n\n\n\n If Alarm A.66 appears, inspect the communication wiring and parameter consistency.<\/p>\n\n\n\n Avoid changing unrelated servo parameters until the communication settings have been verified.<\/p>\n\n\n\n Reliable ESTUN E315P CAN Communication depends on correct configuration of the ED3L servo drives and consistent settings between the controller and connected axes.<\/p>\n\n\n\n The most important parameters are Pn006.0, Pn703, and Pn704.0. Limit detection and datum reference settings must also correspond to the actual machine configuration.<\/p>\n\n\n\n Since these parameters are generally configured at the factory, unnecessary modifications should be avoided. When replacing a servo drive or restoring parameters, follow the manual’s configuration requirements and verify communication before resuming normal machine operation<\/a>.<\/p>\n\n\n\n No. Each servo drive must have a unique Node ID on the CAN network. Duplicate addresses may cause communication conflicts and prevent the controller from identifying the correct servo axis.<\/p>\n\n<\/div>\n<\/div>\n A replacement servo may have different communication settings from the original drive. During ESTUN E315P CAN Communication troubleshooting, verify the CAN control mode, baud rate, and Node ID. Also confirm that the replacement drive is compatible with the machine’s existing configuration.<\/p>\n\n<\/div>\n<\/div>\n Not necessarily. The datum reference setting depends on the machine’s axis configuration. If the corresponding datum function is not required, the manual instructs users to retain the factory defaults.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n Correct ESTUN E315P CAN Communication ensures reliable data exchange between the CNC controller and ED3L servo drives.<\/p>\n\n\n\n The main configuration parameters include Pn006.0 for CAN control mode, Pn703 for communication baud rate, and Pn704.0 for servo Node ID assignment. Limit switch detection and datum reference settings must also match the actual machine wiring.<\/p>\n\n\n\n Since these parameters are normally configured at the factory, unnecessary modifications should be avoided. When replacing servo drives or restoring settings, technicians should verify parameter consistency, inspect communication connections, and confirm normal operation before enabling axis movement.<\/p>\n\n\n\nParam\u00e8tre<\/th> Valeur<\/th> Fonction<\/th><\/tr> Pn006.0<\/td> 1<\/td> Enable CAN Bus Control Mode<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n Step 2: Set the CAN Communication Baud Rate<\/h2>\n\n\n\n
