Motor data and controller adjustments of the asynchronous motor
Main inductance (ASM) / EMC (SM) with rotation (dr.48 = 6)
It is necessary for the identification of the main inductance that the motor accelerates to the speed for maximum
torque (dr.17). The speed controller must be parameterised reasonable (select small Ki), the drive may not
vibrate during the identification.
The motor must be able to rotate in no-
load operation. After the main inductance has been identified, the drive
stops automatically.
There is a special ramp "motor identification ramp
time" (
dr.49) for identification. This ramp applies for accele
-
ration at the beginning and deceleration at the end of the identification.
Dead time detection (dr.48 = 9...13)
The dead
time detection only works as single identification if the stator
resistance is correct preset.
The measured dead time-values can be read out via In.39 and In.40.
The calibrated dead time compensation characteristics are in force if uF.18 = 3 is set.
