Ex factory the frequency inverter is adapted to the supplied motor. If the
motor data in CP.11...18 are changed, then CP.19 must be activated
once. This re-adjusts the current controller, torque curve and torque limit.
With this, the torque limit is set at the value, that is maximally possible in
the speed range (depending on inverter rated current), but not above the
rated motor torque x 3.
CP.19 = 1 : • Pre-adjustment of the motor-dependent control-
parameters.
• The voltage class of the inverter is taken as input voltage.
CP.19 = 2 : • Pre-adjustment of the motor-dependent control-
parameters.
• The DC-link voltage / √2 measured at switch on is taken as
input voltage. Thus the frequency inverter can be adapted
to the actually available mains voltage (e.g. USA with
460 V).
Adjustment range:
Resolution:
Factory setting:
When control release is active the adjustment was not
completed. "nco" appears in the display!
The system position of the attached resolver system is adjusted at CP.20.
With this parameter it is possible to adjust the controller to a not aligned
motor. If the system position of the motor is unknown an automatic
trimming can be done.
Before starting with the adjustment, the direction of rotation must be
checked. The speed display in CP.1 must be positive when the motor
runs manual in clockwise direction. If that is not the case, the direction of
rotation can be exchanged as described with CP.21. If the correct
direction of rotation is displayed, it can be started with the adjustment.
• the connected motor must be able to rotate freely
• open control release (terminal X2A.16)
• CP.20 = 2206 eingeben
• close control release (terminal X2A.16)
