2 Parameters
2.2 List of parameters
For bit 00:
Calculation for the constant and linear coefficients of the moment of inertia precontrol is activated. The results are
written to parameters (p5312, p5313, p5314, p5315).
For bit 01:
The moment of inertia precontrol is activated.
The moment of inertia is calculated from the currently measured load torque and the saved coefficients (p5312,
p5313, p5314, p5315).
Description: Displays the status word for the moment of inertia precontrol.
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, p5312, p5313, p5314, p5315
Description: Setting of the linear coefficients for moment of inertia precontrol in the positive 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 (p5312) * load torque + constant coefficient (p5313)
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, p5313, p5314, p5315
Description: Setting of the constant coefficients for moment of inertia precontrol in the positive 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 (p5312) * load torque + constant coefficient (p5313)
