In the case of bipolar input (terminal [12] with C35 = 0, terminal [V2] with C45 = 0)
Setting C35 and C45 data to "0" enables terminal [12] and [V2] to be used for bipolar input (-10 V to +10 V)
respectively.
When both F18 (Bias) and C50 (Bias base point) are set to "0," the negative and positive voltage inputs produce
reference frequencies symmetric about the origin point as shown below.
Configuring F18 (Bias) and C50 (Bias base point) to specify an arbitrary value (Points A
1
, A
2
, and A
3
)
gives the bias as shown above.
A reference frequency can be specified not only with the frequency (Hz) but also with other menu items,
depending on the setting of function code E48 (= 3 to 5, or 7).
[ 3 ] Using digital input signals UP/DOWN (F01 = 7)
When the
UP/DOWN
control is selected for frequency setting with a run command ON, turning the terminal
command
UP
or
DOWN
ON causes the output frequency to increase or decrease, respectively, within the range
from 0 Hz to the maximum frequency as listed below.
To enable the
UP/DOWN
control for frequency setting, it is necessary to set F01 data to "7" and assign the
UP
and
DOWN
commands to any of digital input terminals [X1] to [X7], [FWD] and [REV] with any of E01 to E07 (data
= 17 or 18).
