SIEPYEUOQ2A01G AC Drive Q2A Technical Manual 571
■ b5-36 PID HiHi Limit Level
No.
(Hex.)
Name Description
Default
(Range)
b5-36
(01A1)
PID HiHi Limit Level
Sets the level that triggers Excessive PID Feedback [FbH] as a percentage of E1-04 [Max 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 HiHi Time],
the drive will detect Excessive PID Feedback [FbH].
■ b5-37 PID HiHi Time
No.
(Hex.)
Name Description
Default
(Range)
b5-37
(01A2)
PID HiHi Time
Sets the length of time that the feedback signal must be more than the level set in b5-36 [PID
HiHi Limit Level] to cause Excessive PID Feedback [FbH].
1.0 s
(0.0 - 25.5 s)
■ b5-38 PID SP User Scale for Display
No.
(Hex.)
Name Description
Default
(Range)
b5-38
(01FE)
PID SP User Scale for
Display
Sets the display for U5-01, U5-04 when the drive operates at the maximum output frequency.
Determined by b5-20
(1 - 60000)
The drive uses this parameter and b5-39 [PID SP User digits for Display] together.
When b5-20 = 4 [PID Unit Selection = ], the drive applies user-set PID setpoint and display units to U5-01 [PID
Feedback] and U5-04 [PID Setpoint].
■ b5-39 PID SP User digits for Display
No.
(Hex.)
Name Description
Default
(Range)
b5-39
(01FF)
PID SP User digits for
Display
Sets the number of digits to set and show the PID setpoint.
2
(0 - 3)
The drive uses this parameter and b5-38 [PID SP User Scale for Display] together.
When parameter b5-20 = 4 [PID Unit Selection = ], the drive applies user-set PID setpoint and display units to
U5-01 [PID Feedback] and U5-04 [PID Setpoint]
0 : No Decimal Places
1 : 1 Decimal Place
2 : 2 decimal places
3 : 3 Decimal Places
■ b5-40 Fref Mon@PID
No.
(Hex.)
Name Description
Default
(Range)
b5-40
(017F)
Fref Mon@PID
Sets the contents for monitor U1-01 [Frequency Reference] in PID control.
0
(0, 1)
0 : U1-01 with PID Output
Monitor U1-01 shows the frequency reference that was increased or decreased by the PID output.
1 : U1-01 without PID Output
Monitor U1-01 shows the actual frequency reference.
■ b5-47 PID Out Rev Operation Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-47
(017D)
PID Out Rev Operation
Mode
Sets reverse motor rotation when the PID control output is negative.
1
(0, 1)
Set b5-01 = 3 or 4 [PID Enable = Fref + PID Trim, Fref + PID Trim (D on feedback)] to enable this parameter.
