Torque Limit settings for SV2A-2150 set in Master/Slave. Using JOG CMD through DI6/DI7

We are using 2 SV2A-2150 drives in a Master-Follower configuration. We're commanding them through the JOG CMDs (DI6/DI7). I'd like to set the torque limit. I set P1.002Y to 1 (ON). Then set P1.012, P1.013, P1.014 to the desired torque %. I do not get a fault output and and the system does NOT seem to work correctly with this settings. Is this the correct strategy to do this?

    In speed mode you should be able to control it on and off for speed moves just with the DI's.

    Check out chapter 6 - Operation Mode manual and look at the Speed Mode section. It is basically like what you are doing with moving forward or back with a jog, but in an actual mode instead.

    Jog commands on some pieces of equipment do not always respect the "rules" set up in various parameters, because it isn't really a mode for the servo or other equipment. This isn't always true, but I have seen it more often than not.

     

    I would try doing your moves through an actual move mode rather than jog, then see if your torque limits are respected.

    To most closely mimic just running the servo in a jog move you could put the servo into S mode (speed) and enable the servo at the speed you want to move. Those torque limit parameters say they function in all modes the servo can do. Your accel and decel parameters will be how fast the servo ramps up and down from the speed you tell it to move at.

      Thanks. Unfortunately we did not purchase a PLC with analog outputs or Motion Control capabilities, thus, we're in that Bang-ON, Bang-OFF type control.
