Parameters 

B 

 

 

Nominal line voltage   

The nominal voltage is the value of the electrical voltage during normal operation specified 

by the manufacturer. The nominal voltage is usually stated with a maximum permissible 

tolerance range. In Europe, the nominal value of the line voltage, the nominal line voltage, is 

230 V (line / neutral) or 400 V (line / line). 

(Warning) threshold for voltage asymmetry   

Voltage asymmetry is the difference between the highest and the lowest phase voltage in 

relation to the highest phase voltage (Ux-y max - Ux-y min) / Ux-y max. 

 

 

Note 
Deviation from the definition according to IEC/NEMA 
The definition given above for voltage asymmetry deviates from the definition according to 

IEC/NEMA. It usually results in a greater value for voltage asymmetry than that arrived at 

from the definition according to IEC/NEMA, so that a higher level of measuring accuracy is 

achieved. 

 

Voltage asymmetry can be parameterized as "Threshold for voltage asymmetry" or as 

"Warning threshold for voltage asymmetry" (only on devices for IO-Link). 
If the warning threshold is reached on device variants for IO-Link, this is transmitted cyclicly 

via IO-Link and the relevant bits are set in the diagnostics data set or the semiconductor 

output (terminal C/Q) is switched in SIO mode. 
If the threshold has been reached, the output relays are switched accordingly and an IO-Link 

message may be sent. 
Possible indications on the display: Asy (threshold), possibly Asy! (warning threshold)
