Feedback Signal Fault Treatment
Default: 0
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: Warn and operate at last frequency
 Valid only when the feedback signal is ACI (4–20 mA).
 Set the treatments when the PID feedback signal is abnormal.

Sleep Level

08-11
Wake-Up Level
Default: 0.00
Settings 0.00–599.00 Hz / 0.00–200.00%
 Determine the sleep level, and if the sleep time and the wake-up level are enabled or disabled.
Pr.08-10 = 0: Disabled; Pr.08-10 ≠ 0: Enabled.
 When Pr.08-18 = 0, the unit for Pr.08-10 and that for Pr.08-11 switch to frequency. The settings
are become 0.00–599.00 Hz.
 When Pr.08-18 = 1, the unit for Pr.08-10 and that for Pr.08-11 switch to percentage. The settings
are between 0.00–200.00%.
 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 command value is 30kg, 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 Detection 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 Feedback Signal Error Deviation Level
and exceeds Pr.08-14 setting, it is regarded as a PID control fault, and the multi-function output
terminal setting 15 (PID feedback error) activates.
