Parameter
Description
Setting
p1563[0...n]
Moment of inertia estimator
load torque positive direc-
tion of rotation [Nm]
Display and connector output for the monitored load
torque in the positive direction of rotation.
Factory setting: 0
p1564[0...n]
Moment of inertia estimator
load torque negative direc-
tion of rotation [Nm]
Display and connector output for the monitored load
torque in the negative direction of rotation.
Factory setting: 0
p5310[0...n] Moment of inertia pre-
control configuration
Configuration of the moment of inertia precontrol when
the moment of inertia estimator is active.
.00 1 signal: Activates calculation of the characteristic
(p5312 … p5315)
.01 1 signal: Activates moment of inertia precontrol
•
p5310.00 = 0, p5310.01 = 0 Deactivating moment of
inertia precontrol
•
p5310.00 = 1, p5310.01 = 0 Adapting the moment of
inertia precontrol
•
p5310.00 = 0, p5310.01 = 1 Activating the moment of
inertia precontrol.
The characteristic of the moment of inertia precontrol
remains unchanged.
•
p5310.00 = 1, p5310.01 = 1 Activating the moment of
inertia precontrol. The converter adapts the character-
istic in parallel.
Factory setting: 0000 bin
r5311[0...n] Moment of inertia pre-
control status word
Displays the status word for the moment of inertia precon-
trol.
.00 1 signal: New measuring points for the characteristic of
the moment of inertia precontrol are available
.01 1 signal: New parameters are been calculated
.02 1 signal: Moment of inertia precontrol active
.03 1 signal: The characteristic in the positive direction of
rotation has been calculated and is ready
.04 1 signal: The characteristic in the negative direction of
rotation has been calculated and is ready
.05 1 signal:
The converter writes actual results to the parameter
