Frequency/torque setting by analog input (terminals 1, 2 and 4)
Set the voltage/current input switch referring to the table below.
Terminal 2 Input Specifications
Voltage input (0 to 10V)
Voltage input (0 to 5V)
Stromeingang (0–20 mA)
Terminal 4 Input Specifications
Voltage input (0 to 10V)
Voltage input (0 to 5V)
Stromeingang (0–20 mA)
Tab. 6-106: Settings for the voltage/current input switches
Initial value
NOTES Turn the AU signal on to make terminal 4 valid.
Match the setting of parameter and switch. A different setting may cause a fault, failure or
malfunction.
The terminal 1 (frequency setting auxiliary input) signal is added to the main speed setting
signal of the terminal 2 or 4.
When an override is selected, the terminal 1 or 4 is used for the main speed setting and the
terminal 2 for the override signal (50% to 150% at 0 to 5V or 0 to 10V). (When the main
speed of the terminal 1 or terminal 4 is not input, compensation by the terminal 2 is made
invalid.)
Use Pr. 125 (Pr. 126) (frequency setting gain) to change the maximum output frequency at
input of the maximum output frequency command voltage (current). At this time, the com-
mand voltage (current) need not be input. Also, the acceleration/deceleration time, which is a
slope up/down to the acceleration/deceleration reference frequency, is not affected by the
change in Pr. 73 setting.
When Pr. 858 "Terminal 4 function assignment", Pr. 868 "Terminal 1 function assignment" =
"4", the value of the terminal 1 or terminal 4 is as set to the stall prevention operation level.
When terminal 1 and terminal 4 are used for frequency setting, set "0" (initial value) in Pr.
858 and Pr. 868.
