Coupling load at maximum and overload conditions The maximum torque is the highest load acting on the coupling in normal operation. Maximum torques at frequency of up to 2 times an hour are permitted and must be lower than the maximum coup-ling torque. Examples of maximum torque conditions are: Starting operations, stopping operations or usual opera - ting conditions with maximum load. Kmax TMax FTOverload torques are maximum loads which occur only in combination with special, infrequent operating conditions. Examples of overload torque conditions are: Motor short circuit, emergency stop or blocking
