■ b5-37: PID High Feedback Detection Time
No.
(Hex.)
Name Description
Default
(Range)
b5-37
(01A2)
PID High Feedback
Detection Time
Sets the length of time that the PID feedback signal must be more than the level set in b5-36 [PID
Feedback High Detection Lvl] to cause Excessive PID Feedback [FbH].
1.0 s
(0.0 - 25.5 s)
■ b5-38: PID User Unit Display Scaling
No.
(Hex.)
Name Description
Default
(Range)
b5-38
(01FE)
PID User Unit Display
Scaling
Sets the value that the drive sets or shows as the PID setpoint when at the maximum output
frequency.
Determined by b5-20
(1 - 60000)
The drive uses this parameter and b5-39 [PID Setpoint Display Digits] together.
When b5-20 = 3 [PID Unit Selection = User Units], the drive applies user-set PID setpoint and display units to
these parameters and monitors:
• b5-19 [PID Setpoint Value]
• b5-58 [PID Setpoint2]
• b5-59 [PID Setpoint3]
• b5-60 [PID Setpoint4]
• U5-01 [PID Feedback]
• U5-04 [PID Setpoint]
• U5-99 [PID Setpoint Command]
■ b5-39: PID User Unit Display Digits
No.
(Hex.)
Name Description
Default
(Range)
b5-39
(01FF)
PID User Unit Display
Digits
Sets the number of digits to set and show the PID setpoint.
Determined by b5-20
(0 - 3)
The drive uses this parameter and b5-38 [PID Setpoint User Display] together.
When b5-20 = 3 [PID Unit Selection = User Units], the drive applies user-set PID setpoint and display units to
these parameters and monitors:
• b5-19 [PID Setpoint Value]
• b5-58 [PID Setpoint2]
• b5-59 [PID Setpoint3]
• b5-60 [PID Setpoint4]
• U5-01 [PID Feedback]
• U5-04 [PID Setpoint]
• U5-99 [PID Setpoint Command]
0 : No Decimal Places (XXXXX)
1 : One Decimal Places (XXXX.X)
2 : Two Decimal Places (XXX.XX)
3 : Three Decimal Places (XX.XXX)
■ b5-40: Frequency Reference Monitor @PID
No.
(Hex.)
Name Description
Default
(Range)
b5-40
(017F)
Frequency Reference
Monitor @PID
Sets the contents for monitor U1-01 [Frequency Reference] in PID control.
0
(0, 1)
0 : U1-01 Includes PID Output
Monitor U1-01 shows the frequency reference that was increased or decreased by the PID output.
1 : U1-01 Excludes PID Output
Monitor U1-01 shows the actual frequency reference.
