192 YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
When you set the output lower limit level in Hz or min
-1
(r/min), refer to b5-91: EZ Sleep Minimum Speed on page
196.
Set this parameter to 0.0% to disable this function.
■ b5-35: PID Input Limit Level
No.
(Hex.)
Name Description
Default
(Range)
b5-35
(01A0)
RUN
PID Input Limit Level
Sets the output upper limit for the PID control as a percentage of the Maximum Output Frequency.
1000.0%
(0.0 - 1000.0%)
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.
(Hex.)
Name Description
Default
(Range)
b5-36
(01A1)
PID High Feedback
Detection Lvl
Sets the level that triggers Excessive PID Feedback [FbH] as a percentage of the Maximum Output
Frequency.
100%
(0 - 100%)
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.
(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.
