Delta Electronics VFD-E manual 13.04, 13.05, 13.06, 13.09, 13.07

Chapter 4 Parameters
13.04	Integral Gain ( I )		Unit: 0.01
	Settings	0.00 to 100.00 sec	Factory Setting: 1.00

0.00Disable

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.

Speed Feedback Display Filter

Unit: 1

Settings

0 to 9999 (*2ms)

Factory Setting: 500

When Pr.0.04 is set to 14, its display will be updated regularly. This update time is set by

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

0.0Disabled

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.
