10 - 07 PID Output Frequency Limit

Settings

00 to 110 %

Unit: 1

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

Settings

0.0 to d 3600.0 sec

Unit: 0.1

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)

Settings

00 Warning and keep operating

01 Warning and RAMP to stop

02 Warning and COAST to stop

Factory Setting: 00

AC motor drive action when the feedback signals (analog PID feedback or PG (encoder)

feedback) are abnormal according to Pr.10-16.
