4 Operation4.4.2 Trial Operation via MECHATROLINK-II4-244.4.2 Trial Operation via MECHATROLINK-IIThe following table provides the procedures for trial operation via MECHATROLINK-II.Step Description Reference1 Confirm that the wiring is correct, and then connect the I/O signal con-nector (CN1 connector). Chapter 3 Wiring and Connection2Turn ON the multi-winding drive unit, SERVOPACK, and converterpower supplies.If the SERVOPACK and converter are receiving power, the CHARGEindicator on the SERVOPACK and converter will light up.Also, the POWER and the COM LED indicators on the SERVOPACKwill light up.Note: If the COM LED indicator does not turn ON, recheck the set-tings of MECHATROLINK-II setting switches (S1001 andS1002) and then turn the power OFF and ON again.–3Send the CONNECT command.In the response data from the multi-winding drive unit, the alarm code“00” is cleared to show normal operation.The response data from the multi-winding drive unit can be confirmedwith the SMON command.Σ-V Series/DC Power InputΣ-V Series/Σ-V Series for Large-Capacity Models User’s ManualMECHATROLINK-II Commands(No.: SIEP S800000 54)4Check the product type using an ID_RD command.A reply showing the product type, such as JUSP-MD3D11A, is receivedfrom the multi-winding drive unit.5Set the following items to the necessary settings for a trial operation.• Electronic gear settings• Rotational direction of servomotor• Overtravel4.4.3 Electronic Gear4.3.1 Servomotor Rotation Direction4.3.2 Overtravel6Save these settings (step 5).If saving the settings in the controller, use the PRM_WR command.To save settings in the multi-winding drive unit, use the PPRM_WRcommand.Σ-V Series/DC Power InputΣ-V Series/Σ-V Series for Large-Capacity Models User’s ManualMECHATROLINK-II Commands(No.: SIEP S800000 54)7Send the SV_ON command.A reply showing that the servomotor has switched to Drive status andthat SVON=1 (servomotor power is ON) is received.8Run the servomotor at low speed.Command used: POSINGCommand setting: Option = 0, Positioning position =10000 (If usingthe absolute encoder, add 10000 to the present position), rapid traversespeed= 400–9Check the following points while running the servomotor at low speed(step 8).• Confirm that the rotational direction of the servomotor correctly coin-cides with the forward rotation or reverse rotation reference. If they donot coincide, reset the direction.• Confirm that no unusual vibrations, noises, or temperature rises occur.If any abnormalities are seen, correct the conditions.Note: Because the running-in of the load machine is not sufficient at thetime of the trial operation, the servomotor may become over-loaded.4.3.1 Servomotor Rotation Direction8.4 Troubleshooting MalfunctionBased on Operation and Conditionsof the Servomotor
