* If the input specification to terminal 4 is changed from the current input (Pr. 267 = "0") to the 0 to 5V or 0 to 10V voltage input (Pr. 267 ="1 or
2"), calibrate the input with C6. (Refer to page 172)

CAUTION
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 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 command 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. 22 Stall prevention operation level = "9999", the value of the terminal 1 is as set to the stall prevention operation level.
When Pr. 561 PTC thermistor protection level "9999", terminal 2 is not available for analog frequency command.
