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

Settings
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.

Gain Over the PID Detection Value

10.10
Settings
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
Settings
10.13

Detection Time of PID Feedback

Settings
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
Settings
10.15 Sleep Frequency
Settings
10.16

Wakeup Frequency

Settings
When the actual output frequency
the AC motor drive will be in sleep mode.
