Consultation Notes

  • Select drives with minimum 200% overload capacity for 3 seconds to handle injection shock loads
  • Implement feedforward compensation in velocity loops to anticipate load changes
  • Configure separate control loops for injection pressure and screw position with cross-coupling compensation
  • Use 24-bit absolute encoders for precise position feedback during high-pressure phases
  • Implement thermal monitoring on motor windings due to intermittent high-torque operation
  • Consider regenerative units for energy recovery during deceleration phases to improve efficiency
