■ b5-56: PID Feedback Monitor Gain
No.
(Hex.)
Name Description
Default
(Range)
b5-56
(0BE2)
PID Feedback Monitor Gain
Sets the gain for the monitor set in b5-55 [PID Feedback Monitor Selection].
1.00
(0.00 - 10.00)
■ b5-57: PID Feedback Monitor Bias
No.
(Hex.)
Name Description
Default
(Range)
b5-57
(11DD)
PID Feedback Monitor Bias
Sets the bias for the monitor specified in b5-55 [PID Feedback Monitor Selection].
0.00
(-10.00 - +10.00)
■ b5-58 to b5-60: PID Setpoints 2 to 4
No.
(Hex.)
Name Description
Default
(Range)
b5-58 to b5-60:
(1182 - 1184)
RUN
PID Setpoints 2 to 4
Sets the PID setpoint when H1-xx = 3E or 3F [MFDI Function Selection = PID Setpoint Selection 1/
2]. This value is a percentage of the maximum output frequency.
0.00%
(0.00 - 100.00%)
Table 2.29 shows how the different MFDI H1-xx values (3E and 3F) have an effect on the PID setpoint value.

OFF OFF No switch
ON OFF b5-58 [PID Setpoint2]
OFF ON b5-59 [PID Setpoint3]

■ 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
