12.1-08-9
 When Pr.08-18 = 0, the unit for Pr.08-10 and that for Pr.08-11 switch to frequency. The settings
are between 0–599.00 Hz.
 When Pr.08-18 = 1, the unit for Pr.08-10 and that for Pr.08-11 switch to percentage. The settings
then are between 0–200.00%.
 The percentage is based on the current command value, not the maximum value. For example,
if the maximum value is 100 kg, and the current value is 30 kg, then if Pr.08-11 = 40%, the value
is 12 kg.

Sleep Delay Time
Default: 0.0
Settings
0.0–6000.0 sec.
 When the Frequency command is smaller than the sleep frequency and less than the sleep time,
the Frequency command is equal to the sleep frequency. However, the Frequency command
remains at 0.00 Hz until the Frequency command becomes equal to or larger than the wake-up
frequency.

PID Feedback Signal Error Deviation Level
Default: 10.0
Settings 1.0–50.0%

08-14
PID Feedback Signal Error Deviation Time
Default: 5.0
Settings 0.1–300.0 sec.

08-15
PID Feedback Signal Filter Time
Default: 5.0
Settings 0.1–300.0 sec.
 When the PID control function is normal, it should calculate the value within a period of time that
is close to the target value.
Refer to the PID control diagram for details. When executing PID feedback control, if |PID
reference target value – detection value| > Pr.08-13 PID Deviation Level and exceeds Pr.08-14
setting, it is judged as a PID control fault, and the multi-function output MO = 15 (PID feedback
error) activates.

PID Compensation Selection
Default: 0
Settings 0: Parameter setting
1: Analog input
 0: The setting for Pr.08-17 gives the PID compensation value.

08-17
PID Compensation
Default: 0
Settings -100.0–100.0%
 The PID compensation value = maximum PID target value × Pr.08-17. For example, if the
maximum operation frequency Pr.01-00 = 60 Hz, and Pr.08-17 = 10.0%, the PID compensation
value increases the output frequency 6.00 Hz. 60.00 Hz × 100.00% × 10.0% = 6.00 Hz
