Note:
• This parameter is disabled when set to 0.0 Hz.
• When b5-53 > 0.0 Hz and the drive enables the integrator ramp limit, the PID integrator value limit is the range set by the output frequency
± b5-53.
• When the PID feedback changes quickly, gradually decrease the value of this parameter in increments of 0.1 Hz to decrease the speed of the
response of PID control.

V/f CL-V/f OLV CLV AOLV
Sets the monitor (Ux-xx) used as the PID Feedback. Set the x-xx part of the Ux-xx [Monitor].
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.
