If
input voltage difference for bias and gain is less than
5%,
drive will not accept the values.
Note:
Adjust bias and gain by applying
5V
(IOV)
across terminals
2
and
5
(frequency setting
input terminals).
While voltage is applied across these terminals, frequency is output corresponding to
the input voltage. For example,
if
the bias and gain are set as explained, output fre-
quency is obtained as shown by the graph (solid line) below
if
1V
is applied across ter-
minals
2
and
5.
When current input is used to control the output frequency, a similar
setting should be made using Pr.904 and Pr.905.
