3.11.4 Speed setting signal on/off selection (Pr. 73 )
*1: The value of terminal 1 (speed setting auxiliary input) is added to the main speed setting signal of terminal 2.
*2: When override has been selected, terminal 1 is for the main speed setting and terminal 2 for the override signal
(50 to 150% at 0 to 10V). (Refer to page 156 for bias/gain adjustment.)
*3: When "30" or "31" is set in Pr. 128, terminal 2 acts as the PID set point function.
*4: When override has been selected, terminal 1 is for speed limit and terminal 2 is for the override signal.
You can select the override function to make main speed setting with the speed setting auxiliary terminal 1.
Using Pr. 73, set the input specifications of terminals 1 and 2 and whether to use the override function or not.
POINT
• Set "0" in Pr. 807 "speed limit selection". (Refer to page 173.)
• Set "0" in Pr. 868 "terminal 1 function selection". (Refer to page 183.)
• Refer to Pr. 902 "speed setting terminal 2 bias", Pr. 903 "speed setting terminal 2 gain" for calibration. (Refer to
page 190.)

CAUTION
To change the maximum output speed at the input of the maximum speed command voltage, use the
speed setting voltage gain, Pr. 903 (Pr. 905).
At this time, the command voltage need not be input.
Also, the acceleration/deceleration time, which is a slope up/down to the acceleration/deceleration
reference speed, is not affected by the change in Pr. 73 setting.
