Example 02: PID positive feedback
 Pr.08-10 must < Pr.08-11
 30kg is the reference
 Set the parameter:
Pr.03-00 = 5 (AVI is PID feedback)
Pr.08-00 = 4 (PID positive feedback: AVI simulation
input function select)
Pr.08-10 = 110% (Sleep reference:
33 kg = 110% × 30 kg)
Pr.08-11 = 120% (Wake-up reference:
36 kg = 120% × 30 kg)
Case 01: If feedback < 33kg, frequency decreases.
Case 02: If feedback > 36kg, frequency increases.

PID Output Command Limit (Reverse Limit)
Default: 100.0
Settings
0.0–100.0%
 When PID enables the reverse direction, the PID output is a negative value, and the PID output
value is limited by the setting for Pr.08-26. Use this function with Pr.08-21.

Acceleration / Deceleration Time for PID Command
Default: 0.00
Settings
0.00–655.35 sec.
 0.00 seconds: Disables the PID acceleration/deceleration command, and the target value is
equal to the PID command.
