p0340 = 4:
--> p1290, p1292, p1293, p1338, p1339, p1340, p1341, p1345, p1346, p1461, p1463, p1464, p1465, p1470, p1472,
p1703, p1715, p1717, p1740, p1756, p1764, p1767, p1780, p1781, p1783, p1785, p1786, p1795
p0340 = 5:
--> p1037, p1038, p1520, p1521, p1530, p1531, p1574, p1750, p1759, p1802, p1803, p2140, p2142, p2148, p2150,
p2157, p2159, p2161, p2162, p2163, p2164, p2170, p2175, p2177, p2179, p2194
Note: p0340 = 1 contains the calculations of p0340 = 2, 3, 4, 5.
p0340 = 2 calculates the motor parameters (p0350 ... p0360).
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.
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: 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: The product of p0341 * p0342 is used when the speed controller (p0340 = 4) is calculated automatically.
Description: Displays the identified rated motor current.
