3.4.3 3-4* Ramp 1
Congure
the ramp time parameters, for each of the 2
ramps (parameter group 3-4* Ramp 1 and parameter group
3-5* Ramp 2). The ramp time is preset to the minimum
value of 10 ms for all power sizes.

Enter acceleration time from 0 Hz to
parameter 1-23 Motor Frequency if
asynchronous motor is selected. Enter
acceleration time from 0 RPM, to
parameter 1-25 Motor Nominal Speed if PM
motor is selected. Select a ramp-up time
such that the output current does not
exceed the current limit in
parameter 4-18 Current Limit during ramping.

If asynchronous motor is selected, enter
deceleration time from
parameter 1-23 Motor Frequency to 0 Hz. If
PM motor is selected, enter deceleration
time from parameter 1-25 Motor Nominal
Speed to 0 RPM. Select a ramp-down time
to avoid tripping on overvoltage in the
DC-link.
