Motor Data Identification 
Parameter Description 
Action 
Setting/ 
Default 
P1910 
Motor Data Identification 
Performs stator resistance 
measuring.  
0 = Disabled.  
 
1 = Identification of Rs with 
parameter change.  
 
2 = Identification of Rs without 
parameter change.  
 
3 = Identification of the saturation 
characteristic with parameter 
change.  
 
20 = Set voltage vector.  
1. Press   to enter the SED2 
parameter mode and to display 
r0000
.  
2. Press   to advance to 
parameter P1910.  
3. Press   to access the 
parameter values level. 
4. Press   to advance to setting 
P1910=1. Press 
 to confirm 
and save the setting. 
 
When P1910=1, Alarm A0541 
(motor data identification active) 
is output and internally P0340 is 
set to 3.  
 
Initiate the measuring operation 
with a continuous (steady-state) 
ON command.  
 
The motor aligns itself and 
current flows through it. 
Diagnostics are possible using 
r0069 (CO: phase current). 
 
On completion of the motor 
data identification routine, 
P1910 resets (P1910=0, motor 
data identification routine 
inhibited) and Alarm A0541 is 
cleared (deleted).  
 
5.  To set the SED2 into a defined 
state, issue an OFF1 command. 
Minimum = 0 
 
Maximum = 20
