The parameters cS.20 and cS.22 define the torque limits.The value ÑoFFì deaktivates
the particular limit. In this case the motoric value is valid. If this value is switched
off too, the preadjusted torque limit in cS.20 is valid for all operating ranges. If
cS.20 is also switched off the value of cS.19 works as limit (especially for CP-
mode).

6.6.4 Torque Limitation
The maximum torque is limited by 2 further factors:
ï 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.
ï From the motor parameters a speed-dependent torque characteristic is
calculated.

Adjustable limits
The torque limits can be modified for special applications in the operation. For that
a source is defined with the parameter cS.15. The defined limits cS.20/cS.22 are
changed with the adjusted torque setpoint source cS.15.
