I am developing an application where a bosch drive and servo motor
screw in and out a connecting rod. This connecting rod has to be supplied with a constant compressive load of 1490 acting against its motion when it screws out and the constant tensile load of 1490 LBF when motor moves in opposite direction causing the connecting road to screw back in.

This load has to be supplied by another bosch indradrive driving a linear exlar motor.

The connecting rod during the period of its motion may be required to accelerate, decelerate and stop. In all conditions, the application requires the constant load supplied by the Linear exlar motor.
Does this constant load requirement requires only setting the parameters in indradrives? If so, what are these?

Many thanks in advance

It's not clear what you are attempting to do, but my understanding from your brief description is that you are driving a rod with one 'intelligent' motor and resisting motion with another.

I'm not familiar with either drive (electric actuator) but have used Emerson precision motors in the past. It would not function as a variable load. Have you checked the drives you have detailed will act as a varaible torque load ?
