Enter the ramp-up time, i.e. the
acceleration time from 0 RPM to
parameter 1-25 Motor Nominal Speed.
Select a ramp-up time such that the
output current does not exceed the
current limit in 4-18 Current Limit during
ramping. See ramp-down time in
parameter 3-42 Ramp 1 Ramp Down Time.

Enter the ramp-down time, i.e. the
deceleration time from
parameter 1-25 Motor Nominal Speed to 0
RPM. Select 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 4-18 Current
Limit. See ramp-up time in
parameter 3-41 Ramp 1 Ramp Up Time.

high limit must exceed the setting in
parameter 4-11 Motor Speed Low Limit
[RPM]. Only parameter 4-11 Motor Speed
Low Limit [RPM] or parameter 4-12 Motor
Speed Low Limit [Hz] is displayed
depending on other parameters in the
Main Menu and depending on default
settings dependant on global location.
