11.3 b: Application
734 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
The drive uses the value set in b5-19 as the PID setpoint.
■ b5-19: PID Setpoint Value
No.
(Hex.)
Name Description
Default
(Range)
b5-19
(01DD)
RUN
PID Setpoint Value
Sets the PID setpoint when b5-18 = 1 [b5-19 PID Setpoint Selection =
Enabled].
0.00%
(0.00 - 100.00%)
■ b5-20: PID Unit Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-20
(01E2)
PID Unit Selection
Sets the units to set and show b5-19 [PID Setpoint Value].
1
(0 - 3)
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
The drive uses 1 min
-1
unit. Set E2-04, E4-04, or E5-04 [Motor Pole Count].
3 : User Units
The drive uses 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.
(Hex.)
Name Description
Default
(Range)
b5-34
(019F)
RUN
PID Output Lower
Limit Level
Sets the output lower limit for the PID control as a percentage of E1-04
[Maximum Output Frequency].
0.0%
(-100.0 - +100.0%)
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.
(Hex.)
Name Description
Default
(Range)
b5-35
(01A0)
RUN
PID Input Limit
Level
Sets the input upper limit for the PID control as a percentage of E1-04
[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 E1-04 [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].
