10 - 07 PID Output Frequency Limit Unit: 1
Settings 00 to 110 % Factory Setting: 100
 This parameter defines the percentage of output frequency limit during the PID control. The
formula is Output Frequency Limit = Maximum Output Frequency (Pr.01-00) X Pr.10-07 %.
This parameter will limit the Maximum Output Frequency. An overall limit for the output
frequency can be set in Pr.01-07.
10 - 08
Feedback Signal Detection Time
Unit: 0.1
Settings 0.0 to d 3600.0 sec Factory Setting: 60.0
 This parameter defines the time during which the PID feedback must be abnormal before a
warning (see Pr.10-09) is given. It also can be modified according to the system feedback
signal time.
 If this parameter is set to 0.0, the system would not detect any abnormality signal.
10 - 09 Treatment of the Erroneous Feedback Signals (for PID and PG feedback error)
Factory Setting: 00
Settings 00 Warning and keep operating
01 Warning and RAMP to stop
02 Warning and COAST to stop
 AC motor drive action when the feedback signals (analog PID feedback or PG (encoder)
feedback) are abnormal according to Pr.10-16.
10 - 16 Deviation Range of PID Feedback Signal Error Unit: 0.01
Settings 0.00~100.00% Factory Setting: 100.00
