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 parameter of the “Initial commis-
sioning” 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.

Explanatory notes
• Since setting of FOR mode represents a fully regulated system with
speed feedback, the “current-controlled startup” function is not
required.
Consequently, as from firmware V. 2.10, to aid commissioning of
field-oriented regulation (FOR) the “current-controlled startup” soft-
ware function is disabled in the presets of the following application
data sets:
- DRV_4, DRV_5
-ROT_2,ROT_3
- M-S_2, M-S_4
• 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.
