2.2 List of parameters
At the end of the calculations, p0340 is automatically set to 0.
If the STARTER commissioning software writes a 3 into p0340 when "downloading to target device", then this
corresponds to a "complete calculation of the motor/control parameters without equivalent circuit diagram data". The
same calculations are carried out as for p0340 = 1, however, without the equivalent circuit diagram parameters of the
motor (p0340 = 2), the motor moment of inertia (p0341) and the motor mass (p0344).
For third-party linear synchronous motors (p0300 = 4) equivalent circuit diagram data are not calculated (p0340 = 2).
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
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: SERVO:
p0341 * p0342 + p1498 influence the speed/torque pre-control in encoderless operation.
VECTOR:
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 (load + motor) and the intrinsic motor moment of inertia (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, p1498
Note: SERVO:
p0341 * p0342 + p1498 influence the speed/torque pre-control in encoderless operation.
VECTOR:
The product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Displays the identified rated motor current.
