■
b5-35: PID Input Limit Level
No.
Name
(Hex.)
b5-35 PID Input Limit Level
(01A0)
RUN
A large input value for PID control makes a high output. The drive applies this limit to the negative and positive
domains.
■
b5-36: PID High Feedback Detection Lvl
No.
Name
(Hex.)
b5-36 PID High Feedback
Detection Lvl
(01A1)
When the feedback signal increases to more than the level set in b5-36 for the time set in b5-37 [PID High Feedback
Detection Time], the drive will detect Excessive PID Feedback [FbH].
■
b5-37: PID High Feedback Detection Time
No.
Name
(Hex.)
b5-37 PID High Feedback
Detection Time
(01A2)
■
b5-38: PID User Unit Display Scaling
No.
Name
(Hex.)
b5-38 PID User Unit Display
Scaling
(01FE)
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.
Name
(Hex.)
b5-39 PID User Unit Display
Digits
(01FF)
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]

V/f CL-V/f OLV CLV AOLV
Sets the output upper limit for the PID control as a percentage of the Maximum Output Frequency.
V/f CL-V/f OLV CLV AOLV
Sets the level that triggers Excessive PID Feedback [FbH] as a percentage of the Maximum Output
Frequency.
V/f CL-V/f OLV CLV AOLV
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].
V/f CL-V/f OLV CLV AOLV
Sets the value that the drive sets or shows as the PID setpoint when at the maximum output
frequency.
V/f CL-V/f OLV CLV AOLV
Sets the number of digits to set and show the PID setpoint.
