Image 7.4: “Determining the mass inertia” screen
NOTE
l
In systems with high static friction, the inertia determination can be
assigned an additional additive speed setpoint.
P 404[0] - CON_
SCON_AddSRamp
can be used for this.
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.

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.
NOTE
l
This function is not recommended for horizontal axes. Attention
must be paid to the mechanical end stops with this function. This
function is only to be used with a freely rotating motor shaft.
NOTE
l
If no values are entered for "Hysteresis Speed" and "Hysteresis
Torque", 20% of the rated speed and 20% of the rated torque is
set. The distance covered results from the preset values.
