6.2 Initial start-up
After all preparatory measures have been carried out and checked the KEB COMBIVERT F5
KEB COMBIVERT F5 can be switched on.
The control release ST (X2A.16) must be deactivated when switching on the first time, since the frequency
inverter is not custom-specific parameterized.
The following descriptions suppose that the frequency inverter is on the password level "application mode"
(ud.01 = application mode). The selection of the password level is described in the manual chapter 4. The start-
up should be executed with COMBIVIS in order to have a short start-up time.
Operating lists are available on the KEB homepage (www.keb.de). This lists contain the necessary parameters
for start-up.
Attention: The start-up instruction manual can only give a short overview of the parameter adjustments which
are mandatory necessary to start-up the motor.
Thus it represents a check list and not a complete parameter description.
The appropriate chapters of the application manual must be read carefully for exact information about the pa-
rameters, additionally points to consider and application-specific adjustments!
The wiring of the motor must be checked before start-up:
- in-phase connection (inverter terminals U, V, W must be connected at the motor terminal board with the
appropriate contacts)
If the wiring is correct the following direction of rotation occurs at setting "clockwise rotation":
- large surface of shield connection, well grounding (see „EMC conform wiring“ in the manual „...before
starting“)
6.2.1 Start-up of an asynchronous motor
The following chapters describe the start-up of an asynchronous motor in the 4 available modes:
⇒
v/f characteristic open-loop operation (F5A-M)
⇒
speed-controlled operation with encoder feedback without motor model (F5A-M)
⇒
speed-controlled operation with encoder feedback with motor model (F5A-M) recommended operating
mode when using a speed feedback)
⇒
speed-controlled operation without encoder feedback (ASCL / F5H-M)
