p0340 = 4 only calculates the controller parameters.
p0340 = 5 only calculates the controller limits.
When quick commissioning is exited using p3900 > 0, p0340 is automatically set to 1.
At the end of the calculations, p0340 is automatically set to 0.
Description: Sets the motor moment of inertia (without load).
Dependency: IEC drives (p0100 = 0): unit kg m^2
NEMA drives (p0100 = 1): unit lb ft^2
The parameter value is included, together with p0342, in the rated starting time of the motor.
Refer to: p0342, r0345
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
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 iner-
tia/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
