MpAxisBasic help inform about torque control, “TorqueLimit, TorqueLimited, Torque/MpAxisTorqueLimitType”
but MappMotion 5.28.3 dont have such variables.
Torque is replaced with Load… and it not work…
ve have MpAxisBasic functio with MoveAbsolute and Jog functions used, we would like to limit torque/load to prevent accidents, while we have x10 too big motors.
what would be best option?
Hello,
for simple limitations you can use the parameters under ‘LimitLoad’ (MpAxisLimitLoadType). MC_LimitLoad will be used for it in the background.
As an more sophisticated alternative you can use MC_BR_LimitLoad_AcpAx.
Hello,
yes “Load” in this case is the same as “Torque”. Can you be more specific what is not working? Are you setting the BOOL command “LimitLoad” on the function block input and the torque parameters? Is there any error on the function block output, or in the Logger?
Like my colleague mentioned, you can also try using MC_BR_LimitLoad_AcpAx. There you have four quadrants that you can limit:
P.S. make sure you are not looking in the help for MpAxisBasic from Legacy mapp, but really in the help for mapp Motion.
This Legacy mapp MpAxisBasic and this mapp Motion MpAxisBasic are not the same.
more likely we cant get motor stop with we add torque over limit.
MpAxisLimitLoadType is not found. MappMotion 5.28.3 AS 4.12.7.113
and yes, command and set is used.
while we have 0.1Nm limit and we monitor 0.2-0-4 load and shaft continue rotate.
and torque limited is not activated.
we also test MC_BR_LimitLoad_AcpAx there limti activation, but same moveabsolute continue moving…
MpAxisLimitLoadType is not found
should be there !? MpAxisLimitLoadType
After setting command ‘LimitLoad’ output ‘LimitLoadReady’ should be set and the limiting value goes to ParID 34855 (VAR_R4_0+7) with mappMotion 5.28.3
The current torque can be traced with parameter TORQUE_ACT.
(The input ‘TorqueLimit’ in the current online help is an issue, the right name is ‘LimitLoad’).
