Chapter 4 Parameters

05Displays the value of the internal counter (c)

06Displays the setting Frequency (F)

07Displays the parameter setting (P)

08Reserved

09Output Current (A)

10Display program operation (0. xxx), Fwd, or Rev

The parameter can be set to display the user-defined value. (where v = H x Pr.65 )

Pr.65	Coefficient K
	Settings	0.01 to 160.0

Unit: 0.01

Factory Setting: 1.00

The coefficient K determines the multiplying factor for the user-defined unit.

The display value is calculated as follows:

Display value = output frequency x K

The display window is only capable of showing four digits, yet you could use Pr.65 to create

larger numbers. The display windows uses decimal points to signify numbers up to three digits

as illustrated in next page:

Display	Number Represented
9999	The absence of a decimal point indicates a four-digit integer.
999.9	A signal decimal point between the middle and the right-most numbers is a true
	decimal point. For example, the number 123.4 would be displayed as “123.4”.
	A single decimal point after the right-most number is not a true decimal point; instead
9999.	it indicates that a zero follows the right-most number. For example, the number 12340
	would be displayed as “1234.”
	Two decimal points (one between the middle and the right-most numbers, and one
999.9.	after the right-most number) are not true decimal points; instead they indicate that two
	zeros follow the right-most number. For example, the number 345600 would be
	displayed as “345.6.”.

Pr.66	Communication Frequency
	Settings 0.00 to 400.0 Hz

Unit: 0.1 Hz

Factory Setting: 0.00

This parameter defines the Master Frequency when the AC drive is controlled by the

communication interface.
