Notes on optimization
Explanatory notes
• The filter time constant for current measurement is used only by the
Sensorless Flux Control (SFC) mode.
• The following functions are operated with the parameters deter-
mined by auto-tuning:
− DC braking
− DC holding
− Remagnetization (VFC)
− Current injection (VFC)
− Torque-forming current i
q
in SFC
− Flux and torque-forming current in FOR
• The factory setting of the current controller relates to an IEC stand-
ard motor with the respective device power rating. The motor is
specified in subject area “_15 FC-Initial commissioning” (section ).
• With the analog input ISA01 by way of FISA1=SCALE the current
can be influenced for torque formation within CLIMx. A torque limita-
tion can thus be effected by way of the analog input.

Need for optimization
VFC
Motor power output = inverter output and IEC standard motor
• No optimization required, because 1:1 rating in factory setting
Motor output power < inverter output or no IEC standard motor
• Optimization and adaptation by activation of auto-tuning
(see section 5.1 “_15 FC-Initial commissioning”)
SFC
Optimized after successful initial commissioning with auto-tuning
(see section 5.1 “_15 FC-Initial commissioning”).
Further information: Setting aids as required in section 6.2.3 “Tips and opti-
mization aids for control engineers”.
FOR
Optimized after successful initial commissioning with auto-tuning
(see section 5.1 “_15 FC-Initial commissioning”).
