I'm trying to activate torque liming on the axis, but can't solve one problem - after execution of _enableTorqueLimiting with default parameters the effective torque on the drive becomes 0.0 so params r1538 and r1539 of axis drive. How i should connect torque limit scaling in the confuguration?

Unfortunately i have no access to this document for some reason, so does it "Simotion FAQ: Howcan the technological data coupling be used with the drive?" or it's another document? Actually i'm interested in Torque limiting via torque reduction as in Axis Fundamentals part 2.15. There is something that i misunderstood and it won't work in proper way.

ThomasD Posts: 39 Rating: (9)	Hello Andrew_097 This FAQ describes not the technological data coupling. In this FAQ the conditions for the function _enabletorquelimiting are summarized. Can you please a little more exactly describe what does not function, what you have done and what you want to reach? Which type of axis do you use (rotary or linear)? How you would like to program the torque limiting value (in % or KN or Nm ...)? Should the force or the torque refer to the load side (gear ratio is always taken into account)? Or should the limit value be interpreted as torque referring to the drive side (gear ratio is not taken into account)? The simplest way for the torque limiting is to program in %-value of the maximum motor torque by the following procedure (procedure applies rotary and linear axes; program must be written in ST code): Configuration data: TypeOfAxis.SetPointDriverInfo.DriveData.maxTorque= max. torque of the motor TypeOfAxis.SetPointDriverInfo.DriveData.forceReductionGranularity = STANDARD System data: userDefaultTorqueLimiting.torqueLimit = max. torque of the motor (same value as “maxTorque”) Parameter SINAMICS drive: P1544 = 100 Call of _enabletorquelimiting: _MccRetDINT := _enabletorquelimiting( axis:=my_axis_name, //axis name torquelimittype:=USER_DEFAULT, torquelimit:= my_torque_limit,//torque limit value in % nextcommand:=IMMEDIATELY, commandid:=getCommandId(), torquelimitunit:= TORQUE ); Regards ThomasD

Thanks a lot for your answer, it woking now except getting error F01912 IF1: PB/PN clock cycle synchronous operation sign-of-life failure when reissuing or disabling torque limiting :) I have a rotary axis and have already done steps described in technology data coupling and tryed to call _enabletorquelimiting with default values of last 3 parameters. userDefaultTorqueLimiting.torqueLimit also was with it's default value 10.0 - i didn't understand it's meaning, so reading help topics more carefully one more time is my task for today. So, thanks again for your help

ThomasD Posts: 39 Rating: (9)	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) M_load= M_motor*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

Still have no access to the document, may be because of i'm not a customer :) Nevertheless, torque limiting working now because of your help. But i still can't understand reason of F01912 IF1: PB/PN clock cycle synchronous operation sign-of-life failure during reissuing/disabling torque limit, and most strange thing in this all is that drive now not accepting positioning command. Can you advice something to solve?

ThomasD Posts: 39 Rating: (9)	Hello Andrew_097 Can it be that the controller goes to stop when you execute the program? Please have a look into the diagnostic buffer. If you get not solved the problem please contact the hotline: Tel: ++49 (0) 180 5050 222 Fax: ++49 (0) 180 5050 223 New Support Request: http://www.siemens.com/automation/support-request Regards ThomasD

Andrew_097 Advanced Member Joined: 3/26/2008 Last visit: 9/6/2024 Posts: 51 Rating: (0)	Hello Thomas. Controller goes to stop only when fault appears - this is because of there is no program for error handling in the project. I created another project from very beginning and noweverything is ok, at least my further experiments. As i understood, in any case i have to extend profibus message frame and make necessary connections to read actualtorque.value of an axis. Alsoare there any means to read effective torque limit on the drive, except of reading drive parameters?
	Last edited by: Andrew_097 at: 4/9/2008 7:56 AM i've noticed that error 1912 appears only when i connected to sinamics integrated, during my online session on controller. Is it necessary to be offline whith Sinamics Integrated heving axes configured already?

ThomasD Posts: 39 Rating: (9)	Hello Andrew_097 1.) There are only the two possibilities around to read drive data. Either you extend the profibus telegram (for cyclic data transfer) or you read the data with the function _readdriveparameter (for acyclic data transfer). 2.) The alarm 1912 is generated by the drive. Therefore you get shown the alarm 1912 only when you be online with the drive (Sinamics Integrated). Unfortunately I cannot determine whether during the telegram extension everything was made correctly. Therefore I would suggest that you let your project check at the hotline. Regards ThomasD
