signal NO
Assume that X20 is used as the NO 
input of emergency evacuation 
signal.
F5-31 23

It is used to notify that ARD 
emergency evacuation is completed.
The parameter setting related to emergency evacuation by shorting stator braking is 
described in the following table.
Function 
Code
Value Description Remarks
F8-10
0: Motor not 
running
Emergency evacuation 
operation mode at 
power failure
-
F5-20 (X20) 27
Emergency evacuation 
signal NO
Assume that X20 is used as the NO 
input of emergency evacuation 
signal.
F5-31 23
Emergency evacuation 
completed
It is used to notify that ARD 
emergency evacuation is completed.
Pay attentions to the following precautions:
 
◆
Select the ARD with the nominal output power equal to or larger than the 
motor rated power.
 
◆
For the 380 V elevator ARD, only two phases are used for emergency evacua-
tion output, and you need to ensure that wiring to the controller is correct; 
the output is single-phase 380 V, and you need to ensure that the transform-
er meets the requirements on the input side.
 
◆
If CAN communication is used, F5-20/F5-31 needs not be set for ARD emer-
gency evacuation.
