3-16 Reference 2 Source
Option: Function:
Select the input to be used for the 2nd
reference signal. Parameter 3-15 Reference 1
Source, parameter 3-16 Reference 2 Source,
and parameter 3-17 Reference 3 Source
define up to 3 different reference signals.
The sum of these reference signals defines
the actual reference. See also

Programming Guide
4.4.3 3-4* Ramp 1
Configure 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.

Function:
[0.05 - Enter acceleration time from 0 Hz to
3600 s] 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.
See ramp-down time in
parameter 3-42 Ramp 1 Ramp Down Time.
Function:
[0.05 - If asynchronous motor is selected, enter
3600 s] 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.
