5.8 Limiting Torque5-595 Operation5.8 Limiting TorqueThe SERVOPACK provides the following four methods for limiting output torque to protect the machine.Note: The maximum torque of the servomotor is used when the set value exceeds the maximum torque.5.8.1 Internal Torque LimitThis function always limits maximum output torque by setting values of following parameters.The setting unit is a percentage of the rated torque.Note: If the settings of Pn402 and Pn403 are too low, the torque may be insufficient for acceleration or deceleration of theservomotor.Torque waveformLimiting Method Description Reference Sec-tionInternal torque limit Always limits torque by setting the parameter. 5.8.1External torque limit Limits torque by input signal from the host controller. 5.8.2Torque limiting by analogvoltage reference Assigns a torque limit by analog voltage reference. 5.8.3External torque limit + Torquelimiting by analog voltage ref-erenceCombines torque limiting by an external input and by analog volt-age reference. 5.8.4Pn402Forward Torque Limit ClassificationSetting Range Setting Unit Factory Setting When Enabled0 to 800 1% 800 Immediately SetupPn403Reverse Torque Limit ClassificationSetting Range Setting Unit Factory Setting When Enabled0 to 800 1% 800 Immediately SetupSpeed Position TorqueSpeed Position TorqueSpeedMaximum torquetSpeedPn403Pn402Limiting torquetNo Internal Torque Limit(Maximum torque can be output) Internal Torque Limit Rotation
