NOTE
• When the slope of the frequency is changed after calibration of terminal 2, the slope of the frequency is also changed for
terminal 1.
• When voltage is applied to terminal 1 while calibration of terminal 2 or terminal 4 is in progress, the terminal 1 input value is
added to the terminal 2 (4) input value.
• 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 follows:
Analog command (via terminal 2 or 4)
(depending on the settings of Pr.73
(Pr.267) and the voltage/current input
selection switch)
0 to 5 V input
0 to 10 V input
0 to 20 mA input
NOTE
• When voltage is applied to terminal 1 while the terminal 1 input specification (0 to ±5 V, 0 to ±10 V) does not agree with the
main speed (terminal 2 or terminal 4 input) specification (0 to 5 V, 0 to 10 V, 0 to 20 mA), the analog input is not correctly
displayed. (For example, when 0 V is applied to terminal 2 and 10 V is applied to terminal 1 in the initial status, the value is
indicated as 5 V (100%).)
Set "0 (initial value)" in Pr.241 to use the % display.
Pr.241 = 0 (initial value)
0 to 100% (0.1%)
0 to 100% (0.1%)
0 to 100% (0.1%)
Pr.241 = 1
0 to 5 V (0.01 V)
0 to 10 V (0.01 V)
0 to 20 mA (0.01 mA)
