If only one torque limitation is necessary for all 4 quadrants (standard condition in
speed controlled operation), then the values CS. 7...CS.9 can be set to „off". Then the
torque limit adjusted in CS.6 applies to all 4 operating areas (motoric/generatoric/
clockwise and counter-clockwise rotation).
The maximum torque is limited by 2 further factors:

• If the KEB COMBIVERT is dimensioned too small to operate the current that
is necessary for the required torque, then the maximum torque is limited
automatically.
• From the motor parameters a speed-dependent torque characteristic is
calculated.
The motor torque which has been calculated from the motor parameters is displayed
in dr.9.
Parameter dr.10 indicates the maximum torque which is achieved in the base speed
range. It depends on the hardware current limitation and cannot be altered.
