7.2.1.1Adjustmentofthemassinertia
If the mass inertia value is not known, the wizard can be used to determine it (see
Section "Automatic inertia detection" on page 114).
NOTE
l
While the mass inertia is being determined the motor executes
movements. There is a risk that the system and the motor may be
destroyed.

CAUTION! Your system/motor may be damaged if put into operation in
an uncontrolled or inappropriate manner.
Improper conduct can cause damage to your system /
machine.
l Beforethe“Start”step,makeabsolutelysurethatavalid
setpointhasbeenentered,astheconfiguredsetpoint
willbeimmediatelytransmittedtothemotorafterthe
motorcontrolfunctionstarts,whichmayresultinthe
motoracceleratingunexpectedly.
7.2.1.2Adaptationtotherigidityofthedrivetrain
The settings for the speed and position control with feed forward control are
determined automatically by setting the rigidity. The rigidity is stated in percent in the
wizard.
l Thesetting<100%reducesthedynamicperformanceofthecontroller
setting(e.g.foratoothedbeltdrive).
l Thesetting>100%increasesthedynamicperformanceofthecontroller
setting(lowplayandelasticity).
The speed controller gain is scaled separately using the percentage value KP Scale.
The damping of the control is affected by the speed filter.
Useful settings are:
l Resolver:1-2ms
l SinCosencoder(low-track):0.5-1ms
l SinCosencoder(highresolution):0.2-0.6ms
