Ambient motor temperature
(entered in °C)
The motor ambient temperature is entered at the instant that motor data is
being determined (factory setting: 20 °C).
The difference between the motor temperature and the motor ambient
temperature must lie in the tolerance range of approx. ± 5 °C. If this is not
the case, then the motor data identification routine can only be carried-out
after the motor has cooled down.
P1910 = 1 Select motor data identification
0 Disabled
1 Identification of all parameters with parameter change
NOTE:
For P1910 = 1
→ P0340 is internally set to P0340 = 1 and the
appropriate data calculated (refer to parameter list P0340)
ON Power-up the motor
The
ON command initiates the measuring operation. In so doing the motor aligns
itself and conducts current. Alarm message A0541 (motor data identification
routine active) is output.
