10.09Treatment of the Erroneous Feedback Signals (for PID feedback error)

Factory Setting: 0

Settings	0	Warning and RAMP to stop
	1	Warning and COAST to stop
	2	Warning and keep operating

This function in only for ACI signal.

AC motor drive action when the feedback signals (analog PID feedback) are abnormal according to Pr.10.16.

10.10	Gain Over the PID Detection Value		Unit: 0.1
	Settings	0.0 to 10.0	Factory Setting: 1.0
This is the gain adjustment over the feedback detection value. Refer to PID control block
diagram in Pr.10.06 for detail.
10.12	PID Feedback Level		Unit: 0.1
	Settings	1.0 to 50.0%	Factory Setting: 10.0
10.13	Detection Time of PID Feedback		Unit: 0.1
	Settings	0.1 to 300.0 sec	Factory Setting: 5.0

This parameter is used to set detection of the offset between set point and feedback. When the offset is higher than (the setting of Pr.10.12 X Pr.01.00) for a time exceeding the setting of Pr.10.13, the AC motor drive will output a signal when Pr.03.00 is set to 16 and will act according to Pr.10.20.

10.14	Sleep/Wake Up Detection Time		Unit: 0.1
	Settings	0.0 to 6550 sec	Factory Setting: 0.0
10.15	Sleep Frequency		Unit: 0.01
	Settings	0.00 to 600.0 Hz	Factory Setting: 0.00
10.16	Wakeup Frequency		Unit: 0.01
	Settings	0.00 to 600.0 Hz	Factory Setting: 0.00

When the actual output frequency ≤ Pr.10.15 and the time exceeds the setting of Pr.10.14, the AC motor drive will be in sleep mode.
