Ambient motor temperature (entered in °C)The motor ambient temperature is entered at the instant that motor data isbeing determined (factory setting: 20 °C).Motortemp. - P0625@€ ± 5 °C ?yes noMotor temp. − P0625≤ 5 °C?The difference between the motor temperature and the motor ambienttemperature P0625 must lie in the tolerance range of approx. ± 5 °C. If thisis not the case, then the motor data identification routine can only becarried-out after the motor has cooled down.Allow the motorto cool downP1910 = 1 Select motor data identification0 Disabled1 Identification of all parameters with parameter change.These changes are made and applied to the controller.3 Identification of saturation curve with parameter changeNOTE:For P1910 = 1 → P0340 is internally set to 3 and the appropriate datacalculated (refer to parameter list P0340)ON Power-up the motorThe ON command initiates the measuring operation. In so doing the motor alignsitself and conducts current. Diagnostics via r0069 (CO: phase currents) ispossible. Alarm message A0541 (motor data identification routine active) isoutput.A0541 After the motor data identification routine has been completed:1. P1910 is reset (P1910 = 0)2. A0541 is withdrawnP1910 = 3 Select motor data identification0 Disabled1 Identification of all parameters with parameter change.These changes are made and applied to the controller.3 Identification of saturation curve with parameter changeNOTE:For P1910 = 1 → P0340 is internally set to 3 and the appropriate datacalculated (refer to parameter list P0340)ON Power-up the motorA0541 After the motor data identification routine has been completed:1. P1910 is reset (P1910 = 0)2. A0541 is withdrawnIf problems occur during the identification run, e.g. the current controller oscillates,then the rating plate data should be re-checked and an approximately correctmagnetizing current P0320 entered. The motor data identification routine shouldthen be re-started by calling P0340 = 1 (refer to Section 3.5.3).
