13. (T) Multi-Function Input Terminal Parameters
13.4 Frequency setting voltage (current) bias and gain
• Use
Pr.125
to set the output frequency to the frequency command voltage (current) set by
Pr.73 Analog input selection
.
• Set the bias frequency of the terminal 4 input using
C5 (Pr.904)
. (It is initially set to the frequency at 4 mA.)
• Use
Pr.126
to set the output frequency to the 20 mA input of the frequency command current (4 to 20 mA).
• There are three methods to adjust the bias/gain frequency setting voltage (current).
Adjustment by applying voltage (current) between terminals 2 and 5 (4 and 5) to set the voltage (current) at the bias/gain
frequency.
Adjustment by selecting the voltage (current) at the bias/gain frequency without applying voltage (current) between
terminals 2 and 5 (4 and 5).
Adjustment by changing the frequency without adjusting the voltage (current).
NOTE
• Always calibrate the input after changing the voltage/current input signal with
Pr.73 (Pr.267)
and the voltage/current input
selection switch.
Display unit changing for analog input (Pr.241)
• The analog input display unit (%/V/mA) can be changed for analog input bias/gain calibration.
• Depending on the terminal input specification setting of
Pr.73 (Pr.267)
and the voltage/current input switch, the unit of the
displayed value of
C3 (Pr.902), C4 (Pr.903), C6 (Pr.904)
and
C7 (Pr.905)
changes as shown below:
Analog command (via terminal 2 or 4)
(depending on the settings of Pr.73 (Pr.267) and the
voltage/current input selection switch)
Pr.241 = "0 (initial value)"
Pr.241 = "1"
