b5-47: PID Trim Mode Output Reverse Sel
No.
Name
(Hex.)
b5-47 PID Trim Mode Output
Reverse Sel
(017D)
This parameter is enabled when b5-01 = 3 or 4 [PID Mode Setting = Fref + PID Trim, Fref + PID Trim (D on
feedback)].
0 : Lower Limit is Zero
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative Output Accepted
When the PID output is negative, the motor will rotate in reverse.
■
b5-53: PID Integrator Ramp Limit
No.
Name
(Hex.)
b5-53 PID Integrator Ramp Limit
(0B8F)
RUN
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.
■
b5-54: PID Softstarter Cancel Selection
No.
Name
(Hex.)
b5-54 PID Softstarter Cancel
Selection
(0BB7)
Table 12.33 shows how the soft-starter responds to PID input/output.
PID Frequency Reference
Selection
Soft Starter 1
Soft Starter 2
0 : Soft Starter 1
The soft starter process occurs downstream from the PID function. The PID function input functions as the
frequency reference, the PID function output functions as the soft starter input, and the soft starter output
functions as the output frequency.
1 : Soft Starter 2
The soft starter process occurs upstream from the PID function. The soft starter input functions as the frequency
reference, the soft starter output functions as the PID function input, and the PID function output functions as the
output frequency.
■
b5-55: PID Feedback Monitor Selection
No.
Name
(Hex.)
b5-55 PID Feedback Monitor
Selection
(0BE1)
Note:
• You cannot select parameter U5-xx.
• This parameter is disabled when set to 000.
