Table 12.33 Switching of MFDI and PID Setpoint Value
H1-xx = 3E H1-xx = 3F PID Setpoint Value
OFF OFF No switch
ON OFF b5-58 [PID Setpoint2]
OFF ON b5-59 [PID Setpoint3]
ON ON b5-60 [PID Setpoint4]
■ b5-61: PID Trim Mode Lower Limit Sel
No.
(Hex.)
Name Description
Default
(Range)
b5-61
(119A)
PID Trim Mode Lower
Limit Sel
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 Trim Mode Lower
Limit Value] 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 Trim Mode Lower Limit Value
No.
(Hex.)
Name Description
Default
(Range)
b5-62
(119B)
PID Trim Mode Lower
Limit Value
Sets the PID Trim Mode Lower Limit Value as a percentage of the maximum output frequency.
0.00%
(0.00 - 100.00%)
Note:
Set b5-01 = 3, 4, 7, or 8 to enable this parameter.
■ b5-63: PID Differential FB Monitor Sel
No.
(Hex.)
Name Description
Default
(Range)
b5-63
(119C)
PID Differential FB
Monitor Sel
Selects the monitor (Ux-xx) used as the PID Differential Feedback. Set the x-xx part of the Ux-xx
[Monitor].
000
(000 - 999)
Note:
• You cannot select parameter U5-xx.
• This parameter is disabled when set to 000.
■ b5-64: PID Differential FB Monitor Gain
No.
(Hex.)
Name Description
Default
(Range)
b5-64
(119D)
PID Differential FB
Monitor Gain
Sets the gain for the monitor specified in b5-63 [PID Differential FB Monitor Sel].
1.00
(0.00 - 10.00)
