Cr09 Switching Frequency; Cr10 Actual Position Filter, Time Constant For Measuring Wheel Mode; Cr10 Actual Position Filter, Time Constant For Measuring Wheel Mode9 - Bosch Rexroth OptiFeed-FS EcoDrive 03 FLP04VRS Functional Description

ECODRIVE03-FL*-04VRS

CR09 Switching Frequency

CR10 Actual Position Filter, Time Constant for Measuring Wheel Mode

DOK-ECODR3-FL*-04VRS**-FK01-EN-P
Recommended Input Value:
Moment
=
CR08
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.

[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.

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.
