No. Parameter Name Setting Range Default
b5-09 PID Output Level Selection 0, 1 0
Setting 0: Normal Output
A positive PID input causes an increase in the PID output (direct acting).
Setting 1: Reverse Output
A positive PID input causes a decrease in the PID output (reverse acting).
n b5-10: PID Output Gain Setting
Applies a gain to the PID output and can be helpful when the PID function is used to trim the frequency reference (b5-01 = 3
or 4).
No. Name Setting Range Default
b5-10 PID Output Gain Setting 0.00 to 25.00 1.00
n b5-11: PID Output Reverse Selection
Determines whether a negative PID output reverses the direction of drive operation. This parameter has no effect when the
PID function trims the frequency reference (b5-01 = 3 or 4) and the PID output will not be limited (same as b5-11 = 1).
No. Parameter Name Setting Range Default
b5-11 PID Output Reverse Selection 0, 1 0
Setting 0: Reverse Disabled
Negative PID output will be limited to 0 and the drive output will be stopped.
Setting 1: Reverse Enabled
Negative PID output will cause the drive to run in the opposite direction.
n b5-12: PID Feedback Loss Detection Selection
Enables or disables the feedback loss detection and sets the operation when a feedback loss is detected.
No. Parameter Name Setting Range Default
b5-12 PID Feedback Loss Detection Selection 0 to 5 0
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).
