Motor Data Identification

Parameter Description
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.

Action
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.
