is the multi-function analog output common. (There are separate commons, terminals 27 and 37, for
the 3G3FV--CUE/CE.)
Multi-function analog output 1 (terminal 21): Outputs the Inverter’s ASR input (0 to ±10 V).
Multi-function analog output 2 (terminal 23): Outputs the actual motor speed (0 to ±10 V).
We recommend monitoring both the ASR input and the motor speed in order to observe a response
delay or deviation from the reference value, as shown in the following diagram.

D Adjusting ASR Proportional Gain 1 (C5-01)
This gain setting adjusts the responsiveness of the speed control loop. The responsiveness is in-
creased
when this setting is increased. Usually this
setting is higher for larger loads. V
ibration will occur
if this setting is increased too much.
The following diagram shows changes that occur in the response when the ASR proportional gain is
changed.
Motor speed
The proportional gain is high.
(Vibration occurs when the gain is too high.)
Time
The proportional gain is low.
