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
