– Dimensioning
KEB COMBIVERT – Motor
If KEB COMIBVERT is dimensioned too small the torque is automatically limited
due to a motor current which is too low.
– Programming the Motor Parameters CP.25 - CP.30
Dependent on the adjusted motor data a speed-dependent limit curve (see below)
is set. The value of the calculated maximum torque is automatically written in
parameter CP.9
Parameter CP.31 (Load motor dependent parameter) activates the motor data and
the respective limit curve.
See table on page 23 for the factory setting of the motor parameter!
