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

V/f CL-V/f OLV CLV AOLV
Sets the gain for the monitor set in b5-55 [PID Feedback Monitor Selection].
V/f CL-V/f OLV CLV AOLV
Sets the bias for the monitor specified in b5-55 [PID Feedback Monitor Selection].
V/f CL-V/f OLV CLV AOLV
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.
