13.04 Integral Gain ( I ) Unit: 0.01
Settings 0.00 to 100.00 sec Factory Setting: 1.00
0.00 Disable
This parameter specifies integral control and associated gain (I), and is used for speed control
with PG feedback.
13.05 Speed Control Output Frequency Limit Unit: 0.01
Settings 0.00 to 100.00Hz Factory Setting: 10.00
This parameter limits the amount of correction by the PI control on the output frequency when
controlling speed via PG feedback. It can limit the maximum output frequency.

Pr.13.06.
13.09 Speed Feedback Filter Unit: 1
Settings 0 to 9999 (*2ms) Factory Setting: 16
This parameter is the filter time from the speed feedback to the PG card.
13.07 Time for Feedback Signal Fault Unit: 0.1
Settings 0.1 to 10.0 sec Factory Setting: 1.0
0.0 Disabled
This parameter defines the time during which the PID feedback must be abnormal before a
warning (see Pr.13.08) 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.
