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
