b5-20: PID Unit Selection
No.
Name
(Hex.)
b5-20 PID Unit Selection
(01E2)
Set the units for 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 : 0.01Hz units
The drive uses 0.01 Hz units.
1 : 0.01% units
The drive uses 0.01% units. Set the value as a percentage of E1-04 [Maximum Output Frequency].
2 : min -1
-1
The drive uses 1 min unit. Set E2-04, E4-04, or E5-04 [Motor Pole Count].
3 : User Units
The drive uses the units set in b5-38 [PID User Unit Display Scaling] and b5-39 [PID User Unit Display Digits]
to show the PID setpoint in U5-01, U5-04, U5-06 [PID Feedback, PID Setpoint, PID Fdbk-Diff PID Fdbk].
■
b5-34: PID Output Lower Limit Level
No.
Name
(Hex.)
b5-34 PID Output Lower Limit
Level
(019F)
RUN
Use a lower limit to keep PID control output from dropping below a fixed level.
Set this parameter to 0.0% to disable this function.
■
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].
