VLT HVAC Drive Programming Guide
Function:
Enter the proportion of the total ramp-up
time (3-41 Ramp 1 Ramp up Time) in which
the acceleration torque increases. The larger
the percentage value, the greater the jerk
compensation achieved, and thus the lower
the torque jerks occurring in the application.
Function:
Enter the proportion of the total ramp-up
time (3-41 Ramp 1 Ramp up Time) in which
the acceleration torque decreases. The larger
the percentage value, the greater the jerk
compensation achieved, and thus the lower
the torque jerks in the application.
Function:
Enter the proportion of the total ramp-down
time (3-42 Ramp 1 Ramp Down Time) where
the deceleration torque increases. The larger
the percentage value, the greater the jerk
compensation achieved, and thus the lower
the torque jerks in the application.
Function:
Enter the proportion of the total ramp-down
time (3-42 Ramp 1 Ramp Down Time) where
the deceleration torque decreases. The
larger the percentage value, the greater the
jerk compensation achieved, and thus the
lower the torque jerks in the application.
