8.9 Limiting Torque8.9 Limiting TorqueThe SERVOPACK provides the following four methods for limiting output torque to protect the machine.SettingLimiting MethodReference SectionLevel1 Internal torque limit 8.9.12 External torque limit 8.9.23 Torque limiting by analog voltage reference 8.9.34 External torque limit + Torque limiting by analog voltage reference 8.9.48.9.1 Internal Torque Limit (Limiting Maximum Output Torque)Maximum torque is always limited to the values set in the following parameters.Pn402 Forward Torque LimitSpeed Position TorqueSetting Range Setting Unit Factory Setting Setting Validation0 to 800 % 800 ImmediatelyPn403 Reverse Torque LimitSpeed Position TorqueSetting Range Setting Unit Factory Setting Setting Validation0 to 800 % 800 ImmediatelyThe settings in these parameters are constantly enabled. The setting unit is a percentage of rated torque.If the torque limit is set higher than the maximum torque of the servomotor, the maximum torque of the servomotor is used(as is the case with the 800% factory setting).No Internal Torque LimitInternal Torque Limit(Maximum Torque Can Be Output)Pn403SpeedMaximum torquetPn402SpeedLimiting torqueToo small a torque limit setting will result in insufficient torque during acceleration and deceleration.88-69
