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

Pr.65

)

Pr.65

Coefficient K

Unit: 0.01

Settings 0.01 to 160.0

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:

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”.

9999.

A single decimal point after the right-most number is not a true decimal point; instead

it indicates that a zero follows the right-most number. For example, the number 12340

would be displayed as “1234.”

999.9.

Two decimal points (one between the middle and the right-most numbers, and one

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

Unit: 0.1 Hz

Settings 0.00 to 400.0 Hz

Factory Setting: 0.00

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

communication interface.
