Torque Command Filters
Description
This document outlines the usage of torque command low-pass and notch filters applicable to the AMD2000
drive. These filters are used to remove unwanted high frequency signals or defined frequency bands (such as
regions of mechanical resonance) in the torque used to drive the machine. Removal of resonant frequency
bands is often desirable to reduce machine noise and vibration, improving lifespan by reducing fatigue or
improving quality in finished products from the machine. The drive can be configured for up to 1 low-pass and 5
notch filters. Only a corner frequency parameter need be set by the user for the low-pass filter, whereas the notch
filters require a centre frequency and a Q factor. The relevant IDN’s that need setting by the user are listed as
follows;

Motor Control Tuning Procedure Command
Th
e parameters in the above IDN’s can be calculated or estimated as follows,
Low-pass filter corner frequency
– signals above this base frequency will be attenuated by more than -3
dB,
Notch filter centre frequency,
– centre frequency of the band needing to be attenuated with the notch,
and
Q factor
– dimension-less parameter which characterises a resonator’s bandwidth relative to its centre
frequency. Q factor is determined from centre frequency
and filter bandwidth
by the relationship,
And the recommended procedure for setting the filter configuration is,
1. Set the associated filter frequency parameter to 1 (ON), or 0 (OFF).
2. Set the above configuration parameters and power cycle the drive. To update without a power cycle,
use the procedure command P-0-0510/33278 Motor Control Tuning Procedure Command by toggling
from 0 to 3.
For parameter details such as data type or scaling, refer to the Digital Servo Drive SoE Parameter Reference
manual (“dd_reference_SoE_parameter.pdf”) supplied with the drive, or located in our online resources.
