Hello Andrew_097 If you work with the command _enabletoquelimiting it is not necessary to execute the steps from the description "technology data coupling". You need for it only the drive standard telegram 102, 105 or 106! The system variable "userDefaultTorqueLimiting.torqueLimit" is only used when you use at the command _enabletoquelimiting the setting torquelimittype=USER_DEFAULT. When you then not program the parameter “torquelimit”, the value in "userDefaultTorqueLimiting.torqueLimit" is interpreted directly as delimitation value. If a value for torquelimit is entered, it will be interpreted as % value related to the torque reduction defined in system variable “userDefaultTorqueLimiting.torqueLimit”. When you let the default value for the parameter “torquelimitunit” then the torque refers to the load side. That means the parameter torquelimit (and system variable "userDefaultTorqueLimiting.torqueLimit") must be calculated by following formula (for a rotary axis): Motor revolution (Gear.numFactor) Mload = Mmotor *Load revolution (Gear.denFactor) All this conditions are described in the FAQ http://support.automation.siemens.com/WW/view/en/22057029. Did you have access to this document in the meantime? Regards ThomasD |

Hello Andrew, when the torque limiting is active with the command _enabletorquelimiting, the drive is build-up maximal with the programmed limit. That means the maximal actual torque must be equal to the programmed limit. When torque limiting is active it is possible to make axis positioning. Normally the axis must not stop during active torque limitation by an error. Maybe the command _enabletorquelimiting is not active. Which error comes up? I attached a screen shot with a list of important parameters and the FAQ. Best regards ThomasD Attachmenttest.zip (799 Downloads) |
