Note: The calculation is not performed, if the power unit is deactivated.
p0340 = 1 contains the calculations of p0340 = 2, 3, 4, 5 without overwriting the motor parameters from the Siemens
motor lists (p0301 > 0).
p0340 = 2 calculates the motor parameters (p0350 ... p0360), but only if it does involve a Siemens catalog motor
(p0301 = 0).
p0340 = 3 contains the calculations of p0340 = 4, 5.
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.
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/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, 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.
