Transformation Output Torque vs Input Speed     

The Output Torque vs Input Speed chart shown belowclearly illustrates the torque profile throughout all moves.

The user inputs below on the form define the limits and performance margins.

Inputs

Output Torque Limit

  • Systems check reports if the output torque limit has been exceeded
     

Input Speed Limit

  • Systems check reports if the input speed limit has been exceeded
     

Nominal Torque and Mean Input Speed Limits

  • Systems check reports if the nominal output torque limit has been exceeded
