6.2.4 Motor identification
6.2.4.1 Standstill measurement
From Version V1.30 onwards, automatic motor identification is
available. In the case of Siemens motors (P095 = 1, 2 or 5) the motor
type is first selected in P096 or P097. In the case of non-Siemens
motors (P095 = 3 or 4), the rating plate data and number of pole pairs
have to be entered, and then automatic parameterizing is called with
P115 = 1.
After exit from the "drive initial start-up" status with P060 = 1, P115 = 2
is set and hence motor identification is selected. The converter must
now be switched in within 30 s so that measuring can start. The alarm
A078 is set during the 30 s.
The motor shaft can move slightly during the measurement operation.
The motor cables are live. Voltages are present at the converter output
terminals and hence also at the motor terminals; they are therefore
hazardous to touch.
It must be ensured that no danger for persons and equipment can
occur by energizing the power and the unit.
If measurement is not started within 30 s or if it is interrupted by an OFF
command, error F114 is set. The converter status during measurement
is "Motid-Still" (r001 = 18). Measurement is ended automatically, and
the converter reverts to the status "Ready for start-up” (r001 = 009).
Depending on the motor size (rotor time constant), measurement will
take 2 to 10 minutes.
In current-controlled mode (P290 = 0), automatic motor identification
should always be performed during initial start-up.
