3-41 Ramp 1 Ramp Up Time
Range: Function:
Size [ 1.00 - Enter the ramp-up time, i.e. the
related 3600 s] 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

3-42 Ramp 1 Ramp Down Time
Range: Function:
Size [ 1.00 - Enter the ramp-down time, i.e. the
related 3600 s] 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.
