2-78• Procedure for Trial RunCautionNote• Before starting the trial run, set the gain-related parameters to appropriate values to avoidproblems such as oscillation. If the load is removed, be sure to set Pr0.04 “Inertia Ratio” to 0.• During the trial run, use the velocity control mode. Various settings including parametersshould assure safe and positive operation under appropriate velocity control.• If SRV-ON becomes valid during trial run, the display changes to which is nor-mal run through external command.• If such trouble as disconnection of cable or connector occurs during trial run, themotor makes over-run for maximum 1 sec. Pay an extra attention for securing safety.• After finished trial running, return to SELECTION display, referring to structure of each mode(P.2-54).Keep pressing (approx. 5 sec)to shift the decimal point towardleft as the left fig. shows.• Then keep pressing until the display of LED changes to.Not a servo-ready status.(Shuts off the main whenerror occurs.)• After the Servo-ON of preparation step 2 for trial run,the motor runs at the preset speed with Pr6.04 (JPG speed)to Positive direction direction by pressing Negativedirection by pressing .Preparationstep 1Preparationstep 2Not a Servo-Ready.Or SRV-ON signal isnot entered.• Press to call forEXECUTION display.(SET button)SELECTION display EXECUTION display“ ” increases while keeppressing (for approx. 5sec)as the right fig. shows.• Keep pressing until the display changes towhen you execute Motor trial run.15.
