3.4.3 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.

TR150 and TR170
Function:
The sum of these reference signals defines
the actual reference. See also
parameter 1-93 Thermistor Source.
Function:
Select the reference input to be used for
rd
the 3 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.

3-41 Ramp 1 Ramp Up Time
Range: Function:
Size [0.05 - Enter acceleration time from 0 Hz to
related 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.
3-42 Ramp 1 Ramp Down Time
Range: Function:
Size [0.05 - If asynchronous motor is selected, enter
related 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.
3.4.4 3-5* Ramp 2
This parameter group configures ramp 2 parameters.
3-51 Ramp 2 Ramp Up Time
Range: Function:
Size [0.05 - If asynchronous motor is selected, enter
related 3600 s] acceleration time from 0 Hz to
*
parameter 1-23 Motor Frequency. If PM
motor is selected, enter 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 parameter 4-18 Current
Limit during ramping up.
3-52 Ramp 2 Ramp Down Time
Range: Function:
Size [0.05 - Enter deceleration time from
related 3600 s] parameter 1-25 Motor Nominal Speed to
*
0 RPM. Select a ramp-down time such
that the output current does not exceed
the current limit in
parameter 4-18 Current Limit during
ramping down.
