4.12 Fan and Pump Application Preset Detailsn b1-04: Reverse Operation SelectionEnables and disables Reverse operation. For some applications, reverse motor rotation is not appropriate and may causeproblems (e.g., air handling units, pumps, etc.).No. Parameter Name Setting Range Defaultb1-04 Reverse Operation Selection 0, 1 0Setting 0: Reverse operation enabledPossible to operate the motor in both forward and reverse directions.Setting 1: Reverse operation disabledDrive disregards a Reverse run command or a negative frequency reference.n b5-12: PID Feedback Loss Detection SelectionEnables or disables the feedback loss detection and sets the operation when a feedback loss is detected.No. Parameter Name Setting Range Defaultb5-12 PID Feedback Loss Detection Selection 0 to 5 0Setting 0: Digital Output OnlyA digital output set for “PID feedback low” (H2-oo = 3E) will be triggered if the PID feedback value is below the detectionlevel set to b5-13 for the time set to b5-14 or longer. A digital output set for “PID feedback high” (H2-oo = 3F) will betriggered if the PID feedback value is beyond the detection level set to b5-36 for longer than the time set to b5-37. Neither afault nor an alarm is displayed on the digital operator and the drive will continue operation. The output resets when the feedbackvalue leaves the loss detection range.Setting 1: Feedback Loss AlarmIf the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FBL - Feedback Low”alarm will be displayed and a digital output set for “PID feedback low” (H2-oo = 3E) will be triggered. If the PID feedbackvalue exceeds the level set to b5-36 for longer than the time set to b5-37, a “FBH - Feedback High” alarm will be displayedand a digital output set for “PID feedback high” (H2-oo = 3F) will be triggered. Both events trigger an alarm output(H1-oo = 10). The drive will continue operation. The alarm and outputs reset when the feedback value leaves the loss detectionrange.Setting 2: Feedback Loss FaultIf the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FbL - Feedback Low”fault will be displayed. If the PID feedback value exceeds the level set to b5-36 for longer than the time set to b5-37, a “FbH- Feedback High” fault will be displayed. Both events trigger a fault output (H1-oo = E) and cause the drive to stop themotor.Setting 3: Digital Output Only, even if PID Is Disabled by Digital InputSame as b5-12 = 0. Detection remains active when PID is disabled by a digital input (H1-oo = 19).Setting 4: Feedback Loss Alarm, even if PID Is Disabled by Digital InputSame as b5-12 = 1. Detection remains active when PID is disabled by a digital input (H1-oo = 19).Setting 5: Feedback Loss fault, even if PID Is Disabled by Digital InputSame as b5-12 = 2. Detection remains active when PID is disabled by a digital input (H1-oo = 19).n b5-19: PID Setpoint ValueUsed as the PID setpoint if parameter b5-18 = 1.No. Name Setting Range Defaultb5-19 PID Setpoint Value 0.00 to 100.00% 0.00%4.12 Fan and Pump Application Preset Details128 YASKAWA ELECTRIC TOEP YAIP1U 01B YASKAWA AC Drive - P1000 Quick Start Guide
