12.1-08-12
08-61
Feedback of PID Physical Quantity Value
Default: 99.9
Settings 1.0–99.9
08-62
Treatment of the Erroneous PID Deviation Level
Default: 0
Settings 0: Warn and keep operating (no treatment)
1: Fault and coast to stop
2: Fault and ramp to stop
3: Ramp to stop and restart after time set at Pr.08-63
(Without displaying fault and warning)
4: Ramp to stop and restart after time set at Pr.08-63. The number of times
of restart depends on the setting for Pr.08-64.

Default: 0
Settings 0: Frequency command (Pr.00-20, Pr.00-30)
1: Pr.08-66 setting
2: RS-485 serial communication

 Selects the target value source for PID controller.
 When Pr.08-65 = 0, the maximum operating frequency 01-00 is 60Hz, the error is 100%, and
Pr.08-01 = 1.00, the output frequency is ‟1” times of the Pr.01-00 maximum operating frequency,
therefore, the output frequency = 60 × 100% × 1 = 60 Hz.
Calculation formula:
Output frequency = Fmax (Pr.01-00) × error% ((PID reference value (Pr.00-20 / Pr.00-30) - PID
feedback (Pr.08-00)) × Pr.08-01.
 When Pr.08-65 ≠ 0, the internal calculation of Proportional gain will be reduced by 100 times,
that is, when Pr.01-00 Fmax = 60Hz, error = 100%, Pr.08-01 = 1.00, the output frequency is
Pr.01-00 Fmax ‟0.01” times, therefore, the output frequency = 60 × 100% × 0.01 = 0.6Hz.
Calculation formula:
Output frequency = Fmax (Pr.01-00) × error% ((PID reference value (Pr.08-66) - PID feedback
value (Pr.08-00)) × Pr.08-01 × 0.01.
