Note 1 The resistances recommended in the table can be used in most applications. In practical
application, if the demand cannot be met, please contact the manufacturer.
Note 2. When all drivers are changed to external brake resistance, parameters P084/P085/P086
should be modified accordingly. Refer to the corresponding parameter description in
section 5.4.1 for specific modification.
