Function:
Enter the ramp-up time, i.e. the acceleration time from 0 RPM to par.
1-25 Motor Nominal Speed. Choose a ramp-up time such that the output
current does not exceed the current limit in par.4-18
ramping. See ramp-down time in par.3-52

Function:
Enter the ramp-down time, i.e. the deceleration time from par.1-25
Nominal Speed to 0 RPM. Choose a ramp-down time such that no over-
voltage arises in the inverter due to regenerative operation of the motor,
and such that the generated current does not exceed the current limit set
in par.4-18 Current Limit. See ramp-up time in par.3-51
Time.

Function:
Enter the proportion of the total ramp-up time (par.3-51
up Time) in which the acceleration torque increases. The larger the per-
centage 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-up time (par.3-51
up Time) in which the acceleration torque decreases. The larger the per-
centage 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 (par.3-52
down Time) where the deceleration torque increases The larger the per-
centage 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 (par.3-52
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.
