RX Quick Start Guide • DC braking by frequency detection can be selected setting A051 to “02” (Frequency detection). In this case DC braking oper- ates when the output frequency comes down to the one you specified in A052 while the RUN command is still active. Exter- nal DB and internal DC braking are invalid during the frequency detection mode.

RX Quick Start Guide b013 could be used to match the torque characteristic with the load. Output current on the winding is used for this calculation as is proportional to the torque generated by the motor. That’s why the current level has to be set in parameter b012 with a range that goes from 20 to 100% of the inverter rated current.
PROGRAMMING RX In standard operation, inverter uses a reference source selected by A001 for the output frequency which may be a fixed or vari- able value. To enable PID operation is necessary to set A071 to “01” and this will cause the inverter to calculate the target fre- quency or set point.
