=
The moment of inertia is the total sum of the rotor and the reflected load
inertia.
The factor 1000 is needed because of the unit mA.

CR09 Switching Frequency
4
[kHz]
This parameter is used to set the switching frequency of the pulse width
modulation controller to 4 kHz or 8 kHz.
This parameter cannot be changed online.
Input min.: 4 kHz
Input max.: 8 kHz
CR10 Actual Position Filter, Time Constant for Measuring Wheel Mode
000.00
Smoothing Time Constant in ms
When measuring wheel mode is active, the position control loop is closed
using the sum of
• actual position 1 (motor encoder) and the
• filtered difference between actual position 2 and actual position 1
This parameter determines the time constant of the filter used.
The differences in actual position are attenuated in order to minimize any
negative effects caused by poor coupling between encoder 2 and the
motor shaft (e.g., due to the measuring wheel becoming disengaged from
the material).
Actual position 2 by itself stipulates the end position.
See also functional description for: Measuring wheel operating mode.
If the input value = 0, only the measuring wheel is operable.
Input min.: 000.00
Input max.: 327.67
