Increase this setting if ov occurs whenperforming Speed Search after a relatively long period of baseblock.Default: 1.05Min: 1.00Max: 1.20b3-14 Bi-Directional Speed SearchSelection0: Disabled (uses the direction of the frequency reference)1: Enabled (drive detects which way the motor is rotating)Default: <10>Min: 0Max: 1b3-17 Speed Search Restart CurrentLevelSets the Speed Search restart current level as a percentage of the drive ratedcurrent.Default: 150%Min: 0%Max: 200%b3-18 Speed Search RestartDetection Time Sets the time to detect Speed Search restart.Default: 0.10 sMin: 0.00 sMax: 1.00 sb3-19 Number of Speed SearchRestartsSets the number of times the drive can attempt to restart when performing SpeedSearch.Default: 3Min: 0Max: 10b3-24 Speed Search MethodSelection0: Current Detection1: Speed EstimationDefault: 0Min: 0Max: 1b3-25 Speed Search Wait Time Sets the time the must wait between each Speed Search restart attempt.Default: 0.5 sMin: 0.0 sMax: 30.0 s<9> Default setting value is dependent on the drive model (o2-04) and the Drive Duty (C6-01).<10> Default setting is determined by the control mode (A1-02).No. Name Description Settingb4-01 Timer Function On-DelayTime Used to set the on-delay and off-delay times for a digital timer output (H2-=12). The output is triggered by a digital input programmed to H1-=18)Default: 0.0 sMin: 0.0 sMax: 3000.0 sb4-02 Timer Function Off-DelayTimeDefault: 0.0 sMin: 0.0 sMax: 3000.0 sNo. Name Description Settingb5-01 PID Function Setting0: Disabled1: Enabled (PID output becomes output frequency reference, deviation Dcontrolled)2: Enabled (PID output becomes output frequency reference, feedback Dcontrolled)3: Enabled (PID output added to frequency reference, deviation D controlled)4: Enabled (PID output added to frequency reference, feedback D controlled)Default: 0Min: 0Max: 4b5-02 Proportional Gain Setting (P) Sets the proportional gain of the PID controller.Default: 1.00Min: 0.00Max: 25.00b5-03Integral Time Setting (I) Sets the integral time for the PID controller.Default: 1.0 sMin: 0.0 sMax: 360.0 sb5-04Integral Limit Setting Sets the maximum output possible from the integrator as a percentage of themaximum output frequency.Default: 100.0%Min: 0.0%Max: 100.0%b5-05Derivative Time (D) Sets D control derivative time.Default: 0.00 sMin: 0.00 sMax: 10.00 sb5-06PID Output Limit Sets the maximum output possible from the entire PID controller as a percentageof the maximum output frequency.Default: 100.0%Min: 0.0%Max: 100.0%b5-07PID Offset Adjustment Applies an offset to the PID controller output. Set as a percentage of themaximum output frequency.Default: 0.0%Min: -100.0%Max: 100.0%No. Name Description Setting
