4.12 Fan and Pump Application Preset Details

b1-04: Reverse Operation Selection
n
Enables and disables Reverse operation. For some applications, reverse motor rotation is not appropriate and may cause
problems (e.g., air handling units, pumps, etc.).
No.
b1-04
Setting 0: Reverse operation enabled
Possible to operate the motor in both forward and reverse directions.
Setting 1: Reverse operation disabled
Drive disregards a Reverse run command or a negative frequency reference.
b5-12: PID Feedback Loss Detection Selection
n
Enables or disables the feedback loss detection and sets the operation when a feedback loss is detected.
No.
b5-12
Setting 0: Digital Output Only
A digital output set for "PID feedback low" (H2-oo = 3E) will be triggered if the PID feedback value is below the detection
level 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 be
triggered if the PID feedback value is beyond the detection level set to b5-36 for longer than the time set to b5-37. Neither a
fault nor an alarm is displayed on the digital operator and the drive will continue operation. The output resets when the feedback
value leaves the loss detection range.
Setting 1: Feedback Loss Alarm
If 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 feedback
value exceeds the level set to b5-36 for longer than the time set to b5-37, a "FBH - Feedback High" alarm will be displayed
and 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 detection
range.
Setting 2: Feedback Loss Fault
If 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 the
motor.
Setting 3: Digital Output Only, even if PID Is Disabled by Digital Input
Same 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 Input
Same 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 Input
Same as b5-12 = 2. Detection remains active when PID is disabled by a digital input (H1-oo = 19).
b5-19: PID Setpoint Value
n
Used as the PID setpoint if parameter b5-18 = 1.
No.
