CP-Parameter
CP.10 Speed control configuration
This parameter activates the speed or the torque control.
CP.10 Description
4 Speed control
5 Torque control
6 Speed / torque control
CP.19 Load motor dependent parameter
The factory settings of the servo correspond to the size of the unit and the respective
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. The torque limit is set
at the value, that is maximally possible in the basic speed range (depending on inverter
rated current). Rated motor torque x 3 at maximum.
CP.19 Pre-adjustment of the motor-dependent control-parameters.
1 The voltage class of the inverter is taken as input voltage.
The measured DC-link voltage / √2 measured at switch on is taken as input
2 voltage. Thus the frequency inverter can be adapted to the actually available
mains voltage (e.g. USA with 460 V).
When control release is active the adjustment was not completed. „nco" appears in the
display!
CP.20 Absolute position enc. 1
The system position of the attached resolver system is adjusted at EC.07. With this
parameter it is possible to adjust the controller to a not aligned motor. If the ystem 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 at CP.1 must be
positive when the engine 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).
• Set CP.20 = 2206.
• Close control release (terminal X2A.16).
Now the motor is excited with its rated current and aligned to its zero position. The
adjustment is finished when the displayed system position at CP.20 does not change for
approx. 5 s. In this case open control release and switch off the unit.
If the error message E.EnC is displayed during trimming the direction of rotation must be
checked (CP.21). In this case the position trimming must be repeated.
In case that motors with aligned encoder system are used, the value which has been
established by the automatic trimming, can be entered under CP.20 as well. The adjustment
values of known motors of the KEB COMBIVERT S4 series must be multiplied by the pole-
pair number of the motor. The lower 16 bits of the result must be entered in CP.20.
CP.21 Encoder 1 rpotation
The speed display at CP.1 must be positive when the engine runs manual in clockwise
direction. The signals SIN+ and SIN- of the resolver have to be changed, if the sign is
wrong. Please ensure that the signals are not short-circuited with the internal shield.
