6.2 Motor data identification
Factory setting
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).
yes no
The difference between the motor temperature and the motor ambient
temperature P0625 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.
Select motor data identification with P1910 = 1
p1910 = 1: Identifies the motor parameter with parameter change.
When p1910 = 1 is selected, Alarm A0541 (motor data identification active)
is output, and internally p0340 is set to 3.
Starts the motor data identification run with p1910 = 1
The measuring operation is initiated with the continuous (steady-state) ON
command. The motor aligns itself and current flows through it.
After the motor data identification routine has been completed, p1910 is reset
(p1910 = 0, motor data identification routine inhibited) and Alarm A0541 is
cleared (deleted).
In order to set the frequency inverter into a defined state, an OFF1 command
must be issued before the next step.
