Active functions in SFC
Information for auto-tuning
For auto-tuning of the controller and motor parameters the rating plate
data of the motor must be entered in the parameters of the “Initial com-
missioning” subject area (see section 5.1). Precise motor data should be
obtained as necessary from the manufacturer.
The operating points of the motor are set based on these data, so precise
information from the motor manufacturer is important.
Note: Auto-tuning determines the controller and motor parameters
automatically and enters them in the relevant parameters.

Explanatory notes
• In the event of strong load surges resulting in rapid speed changes,
the stator flux orientation of the SFC may be lost, and current over-
load shut-offs (error E-OC) may occur. This is counteracted by the
“current-controlled startup” function (see section 5.5.11) setting a
steep lowering ramp.
• The DC braking and DC holding functions can only be sequenced. If
both functions are activated the DC holding function is not activated
until the braking time has elapsed. No check that the rotor has come
to a standstill is made before activation of the holding time.
• Remagnetization can be deactivated by way of parameter 774-
MPT=0s in subject area “_77 MP-Remagnetization”. During auto-
tuning the remagnetization time is determined automatically.
