are set with the following parameters. T

Note 2. When
a
voltage input is being input to terminal 14, be sure to disconnect jumper wire J1 on the
control
board. The input resistance will be destroyed if a voltage
input is used without discon
-
necting the jumper wire.
Note 3. Set the time constant with the following parameter when adding a primary delay filter to an
analog input:
Analog input filter time constant H3-12.
. .
This filter time constant applies to all three of the analog inputs.
Note 4. The
frequency bias setting (setting: 2) is dif
ferent from the frequency bias 2 setting (setting: D)
in the operation of the Inverter if the calculation results in a negative value. The frequency bias
will be limited to 0 and frequency bias 2 will rotate the motor in the reverse direction.
Note 5. The
frequency bias and frequency bias 2 cannot be set together for two analog inputs. A set
-
ting error (OPE07) will result if an attempt is made to set them.
