Tab. 6-28: Setting of parameter 73 and 267
The terminal used for the AU signal input, set "4" in Pr. 178 to Pr. 182 to assign functions.
NOTES Turn the AU signal on to make terminal 4 valid.
Make sure that the parameter and switch settings are the same. Different setting may cause
a fault, failure or malfunction.
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. 561 ≠ 9999, terminal 2 is not available for analog frequency command.
Changing the terminal assignment using Pr. 178 to Pr. 182 may affect the other functions.
Make setting after confirming the function of each terminal.
