SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 553
Table 12.14 shows how the different MFDI H1-xx values (77 and 78) have an effect on the PID setpoint value.
Table 12.14 Switching of MFDI and PID Setpoint Value
H1-xx = 77 H1-xx = 78 PID Setpoint Value
OFF OFF No switch
ON OFF b5-58 [PID Setpoint 2]
OFF ON b5-59 [PID Setpoint 3]
ON ON b5-60 [PID Setpoint 4]
■ b5-61 PID LoLim Select for Trim Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-61
(119A)
PID LoLim Select for Trim
Mode
Sets the function that adjusts the PID output in relation to the frequency reference.
0
(0, 1)
0 : Disabled
Does not adjust the PID output with the frequency reference.
1 : Enabled
Adjusts the PID output in relation to the frequency reference. The setting value of b5-62 [PID LoLim Value for
Trim Mode] sets the lower limit of the post-adjustment value. The maximum output frequency sets the upper limit.
Note:
• Set b5-01 = 3, 4, 7, or 8 to enable this parameter.
• When b5-61 = 1, you can use this formula to adjust PID output proportional to the frequency reference:
U5-03 [PID Output], Fref [Frequency Reference], and Fmax [Maximum Output Frequency]
*1 Lower limit = b5-62, Upper limit = Maximum output frequency
■ b5-62 PID LoLim Value for Trim Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-62
(119B)
PID LoLim Value for Trim
Mode
Sets the lower limit of the PID frequency reference trim as a percentage where E1-04 [Max
Output Frequency] setting = a setting value of 100%.
0.00%
(0.00 - 100.00%)
Note:
Set b5-01 = 3, 4, 7, or 8 to enable this parameter.
■ b5-63 PID DifFB Mon Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-63
(119C)
PID DifFB Mon Selection
Sets the monitor for PID Differential Feedback (Ux-xx).
000
(000 - 999)
Note:
• You cannot select parameter U5-xx.
• This parameter is disabled when set to 000.
■ b5-64 PID DifFB Mon Gain
No.
(Hex.)
Name Description
Default
(Range)
b5-64
(119D)
PID DifFB Mon Gain
Sets the gain for the monitor specified in b5-63 [PID DifFB Mon Selection].
1.00
(0.00 - 10.00)
Set b5-18 = 1 [b5-19 PID SP Selection = Enabled] to enable this parameter.
