List Manual, 09/2017, A5E33842890
Description:
Sets the constant coefficients for moment of inertia precontrol in the negative direction when the moment of inertia
estimator is active.
The estimated moment of inertia is obtained according to the following formula:
Moment of inertia (J) = linear coefficient (p5314) * load constant coefficient (p5315)
Dependency:
The function module "Moment of inertia estimator" (r0108.10) must be activated for the "Moment of inertia precontrol"
function.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p5310, r5311, p5312, p5313, p5314
Description:
Sets the change time for the moment of inertia for the moment of inertia precontrol.
Lower values mean that faster changes are possible.
For a higher value, this estimated value is smoothed more significantly.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1400, p1560, p1562
Description:
Sets the boost factor for the copper losses at standstill for motor temperature models 1 and 3.
The entered factor is active for speed n = 0 [rpm].
This factor is linearly reduced down to 1 between speeds n = 0 ... 1 [rpm].
The following values are required to calculate the boost factor:
- stall current (I_0, p0318, catalog value)
- thermal stall current (I_th0, catalog value)
The boost factor is calculated as follows:
- p5350 = (I_0 / I_th0)^2
Dependency:
Refer to: p0318, p0612, p5390, p5391
Refer to: F07011, A07012, A07014
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:
Temperature model 1 (I2t):
The following applies for firmware version < 4.7 SP6 or p0612.8 = 0:
- parameter p5350 is not active. Internally, a fixed boost factor of 1.333 is used as basis for the calculation.
The following applies from firmware version 4.7 SP6 and p0612.8 = 1:
- parameter p5350 becomes active as described above.
