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
