Keba ServoOne - Automatic Inertia Detection

NOTE
l
After a power-off the speed and position control settings remain
stored. The percentage value for rigidity, however, is set to 100%
again.
7.2.2Automaticinertiadetection
To define the mass inertia of a motor easily, the "automatic mass inertia definition"
function is available. In the standard motor data set, the speed controller is preset for
a moderately stiff mechanical system
.The automatic mass inertia definition function is started when the hardware has
been enabled. Clicking the "Automatic Inertia Definition" button enters the latest
value obtained in SCD_Jsum.

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
