Explanation
Moment of inertia precontrol configuration (factory setting: 0000 bin)
.00 1 signal: Activates calculation of the characteristic (p5312 ... p5315)
.01 1 signal: Activates moment of inertia precontrol
p5310.00 = 0, p5310.01 = 0
p5310.00 = 1, p5310.01 = 0
p5310.00 = 0, p5310.01 = 1
p5310.00 = 1, p5310.01 = 1
Moment of inertia precontrol status word
.00 1 signal: New measuring points for the characteristic of the moment of inertia pre‐
control 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 inverter writes actual results to the parameter

Adapting the moment of inertia precontrol
Activating the moment of inertia precontrol.
The characteristic of the moment of inertia precon‐
trol remains unchanged.
Activating the moment of inertia precontrol. The
inverter adapts the characteristic in parallel.
In a positive direction of rotation:
