Hi,
We are seeing a strange behaviour with MC_Home function block. We are using LMC078 motion controller to control a lexium32S drive from schneider electric. The programming platform is soMachine and the library thats being used is SM3_Basic which is already in the soMachine.
Observation
When we home the linear axis via drive software(soMove) homing is taking place without any jerks and sound. But when we issue homing command via MC_Home function block from PLC the whole axis jerks and sounds are coming. When we analyse the issue with trace, we understood that when we home the axis via drives software, axis is taking the acceleration and deceleration parameters which is in the drive. But while we issue command via MC_Home function block the motor is taking a high acceleration and thats the reason for the jerk and sound.
What we expect from MC_Home function block is that the axis does the homing routine programmed in the drive by itself with the set parameters.
But in our case acceleration and deceleration is taking some other value
Homing method : Moving to reverse limit and search for motor index pulse.
Does anyone faced a similar issue with MC_Home command?
