Details of parameter[Class 5] Enhancing settingPr5.08 Title LV trip selection at main power OFF Relatedcontrol mode P S T FRange 0 to 1 Unit — Default 1CautionYou can select whether or not to activate Err13 (Main power under-voltage protection)function while the main power shutoff continues for the setup of Pr5.09 (Main power-OFFdetection time).Setup value Action of main power low voltage protection0When the main power is shut off during Servo-ON, Err13 will not be triggered and thedriver turns to Servo-OFF. The driver returns to Servo-ON again after the main powerresumption.1 When the main power is shut off during Servo-ON, the driver will trip due to Err13 (Mainpower low voltage protection).This parameter is invalid when Pr5.09 (Detection time of main power OFF)=1000. Err13 (Mainpower under-voltage protection) is triggered when setup of P5.09 is long and P-N voltage ofthe main converter falls below the specified value before detecting the main power shutoff,regardless of the Pr5.08 setup.Pr5.09 * Title Detection time of main power off Relatedcontrol mode P S T FRange 70 to 2000 Unit 1ms Default 70You can set up the time to detect the shutoff while the main power is kept shut off continuously.The main power off detection is invalid when you set up this to 2000.Pr5.10 Title Sequence at alarm Relatedcontrol mode P S T FRange 0 to 7 Unit — Default 0Specify the status during deceleration and after stop, after occurrence of alarm.Setupvalue During deceleration *3 After stallingPositional deviation/feedback scaledeviation0 Dynamic Brake (DB) action Dynamic Brake (DB) action Clear *11 Free-run (DB OFF) Dynamic Brake (DB) action Clear *12 Dynamic Brake (DB) action Free-run (DB OFF) Clear *13 Free-run (DB OFF) Free-run (DB OFF) Clear *14 Action A: Emergency stopAction B: DB action *2 Dynamic Brake (DB) action Clear *15 Action A: Emergency stopAction B: DB OFF *2 Dynamic Brake (DB) action Clear *16 Action A: Emergency stopAction B: DB action *2 Free-run (DB OFF) Clear *17 Action A: Emergency stopAction B: DB OFF *2 Free-run (DB OFF) Clear *1*1 Positional deviation/feedback scale deviation is maintained during alarm condition and will becleared when the alarm is cancelled.*2 Action of A/B: When an alarm requiring emergency stop occurs, the action A is selected when thesetup value in the table is set within the range 4 to 7, causing emergency stop of operation. Whenan alarm not requiring emergency stop occurs, it triggers dynamic braking (DB) specified by actionB, or free-running.*3 Deceleration period is the time required for the running motor to speed down to 30 r/min.
