■
b5-53: PID Integrator Ramp Limit
No.
(Hex.)
Name Description
Default
(Range)
b5-53
(0B8F)
RUN
PID Integrator Ramp Limit Sets the responsiveness of PID control when the PID feedback changes quickly. 0.0 Hz
(0.0 - 10.0 Hz)
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 this parameter in 0.1 Hz increments to decrease the speed of the response
of PID control.
■
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 [PID Mode Setting = Fref + PID Trim] 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 [PID Mode Setting = Fref + PID Trim] to enable this parameter.
■
b5-68: System Unit Custom Character 1
