2.2 List of parameters
Description: Setting of the linear 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 torque + constant coefficient (p5315)
Dependency: The function module "Moment of inertia estimator" (r0108.10) must be activated for the "Moment of inertia precontrol"
function.
Refer to: p5310, r5311, p5312, p5313, p5315
Description: Setting of 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 torque + constant coefficient (p5315)
Dependency: The function module "Moment of inertia estimator" (r0108.10) must be activated for the "Moment of inertia precontrol"
function.
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: 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].
