  • Page 100: Advanced Adjustments

    Advanced Parameters 8.0 Advanced Adjustments There are additional US parameters which can provide further functional adjustments of the drive. This US parameters are all those greater than US.10. They are turned ON or OFF through parameter US.8. Once turned ON, the higher US parameters are unlocked and can be adjusted as needed.

  • Page 101: Pre-Torque Timer Ramp Up

    Advanced Parameters US. 17 This timer controls the build time for the Pre-torque function. Once the direction input is activated this timer begins counting. In the mean time the current check takes Pre-torque place and then finally the motor is magnetized. At this point the Pre-torque value is timer ramp up evaluated and the torque begins to build on the motor.

  • Page 102: Field Weakening Corner

    Advanced Parameters This parameter provides a better adjustment of the field weakening torque curve. US. 19 Under certain situations, if the input voltage is sagging too low or the motor has very high slip, it is possible that the voltage limit might be reached. This can be confirmed Field by monitoring ru.42.

  • Page 103: Speed For Max Ki

    Advanced Parameters These parameters can be used to tailor the KI Offset gain to a specific speed range US. 20 at low speed. Worm gear applications require a smaller KI Offset value but over a broader speed range. Whereas a gearless motor will require a much higher KI Offset Speed for Max value but at only the very lowest speed.
