1 Auxiliary frequency

reference (FREF2)

When frequency reference 2 is select-

ed using the multi-step speed referenc-

es, the input analog signal for the CN2

terminal will be the frequency refer-

ence. The n025 setting will be invalid.

Note:Set the Frequency Reference Gain in

n068 or n071, and the Frequency Refer-

ence Bias in n069 or n072.

2 Frequency refer-

ence gain (FGAIN)

Set the FGAIN to constant n060 or

n074 and the FBIAS to constant n061

or n075 for the master frequency refer-

ence. Then, multiply the resulting fre-

quency reference by the FGAIN.

3 Frequency refer-

ence bias (FBIAS)

Set the FGAIN to constant n060 or

n074 and the FBIAS to constant n061

or n075 for the master frequency refer-

ence.

Then, add the FBIAS to the resulting

frequency reference.

Then amount of the FBIAS to be added

is set to n079.

4 Output voltage bias

(VBIAS)

Add the VBIAS to the output voltage af-

ter V/f conversion.
