Note: The product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Sets the ratio between the total moment of inertia/mass (load + motor) and the intrinsic motor moment of inertia/mass
(no load).
Dependency: This means that together with p0341, the rated starting (accelerating time) of the motor is calculated for a vector
drive.
Refer to: p0341, r0345
Note: The product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Displays the identified rated motor current.
Description: Sets the motor weight.
Dependency: IEC drives (p0100 = 0): unit kg
NEMA drives (p0100 = 1): unit lb
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: The parameter influences the thermal 3 mass model of the induction motor.
The parameter is not used for synchronous motors (p0300 = 2xx).
Description: Displays the rated motor starting time.
This time corresponds to the time from standstill up to reaching the motor rated speed and the acceleration with
motor rated torque (r0333).
Dependency: Refer to: r0313, r0333, p0341, p0342
