2.2 List of parameters
For bit 05:
The maximum setpoint acceleration for the basic positioner (EPOS) is determined based on the estimated moment of
inertia. This is realized by activating the bit once.
The prerequisite is that the drive pulses are inhibited, and the moment of inertia was previously determined.
For bit 06:
The speed controller gain set in p1460 is not changed when calculating the controller data.
p5310[0...n] Moment of inertia precontrol configuration / J_est config
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
-
Description: Configuration of the moment of inertia precontrol when the moment of inertia estimator is active.
Bit field: Bit
00
01
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: r5311, p5312, p5313, p5314, p5315
Note: Possible bit combinations:
Bit 1, 0
= 0, 0 --> function not active
= 0, 1 --> cyclic calculation of the coefficients without moment of inertia precontrol (commissioning)
= 1, 0 --> moment of inertia precontrol activated (without cyclic calculation of the coefficients)
= 1, 1 --> moment of inertia precontrol activated (with cyclic calculation of the coefficients)
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).
