Hello,
Could anyone explain the difference between configuring the gearbox on the ACOPOS Channel and configuring it directly on the motor?
Also, is there a difference between setting the load limit using the “LimitLoad” input from “MpAxisBasic” versus configuring it in the gearbox settings?
Best regards,
Simon
Hi,
i am not sure if I completely understood your question so excuse if i am completely on the wrong track.
Could anyone explain the difference between configuring the gearbox on the ACOPOS Channel and configuring it directly on the motor?
the gearbox setting in ACOPOS Channel is for scaling the axis (position + speed).
what means ‘directly on the motor’
Also, is there a difference between setting the load limit using the “LimitLoad” input from “MpAxisBasic” versus configuring it in the gearbox settings?
can I assume you mean this here !?

the advantage of gearbox torque limitation: if it is once set correctly it is independend from application settings. MC_BR_LimitLoad parameters may vary in different machine modes. The gear torque limitation should be constant in all modes.

In addition to what Christoph wrote.
The gear ratio in the channel configuration is only used for the unit scaling of the axis.
How many units do we have in how many motor revolutions.
Gearbox/Input = Motor revolutions
Gearbox/Output x ReferenceDistance = Units
(one could set Gearbox/Output to 1 and multiply the actual value into ReferenceDistance and get the same behavior)
The gear ratio in the motor parameters must be set to the actual values so the limitation can work correctly (e.g. Peak output torque).
“LimitLoad” via function block vs. gear box configuration:
Using the configuration is more convinient because the load limit value of the function block refers to the motor shaft, so one would have to transform the “Peak output torque” of the gearbox to the motor shaft manually.
Also “LimitLoad” via function block is intended for applications that need to limit the torque in some situations and not in others.
