Parameter Descriptions
3-41 Ramp 1 Ramp Up Time
Range: Function:
Size [0.05 - Enter the ramp-up time, that is the
related 3600 s] acceleration time from 0 RPM to the
*
synchronous motor speed n
up time such that the output current does
not exceed the current limit in
parameter 4-18 Current Limit during ramping.
The value 0.00 corresponds to 0.01 s in
speed mode. See ramp-down time in
parameter 3-42 Ramp 1 Ramp Down Time.
Par . 3 − 41 =
3-42 Ramp 1 Ramp Down Time
Range: Function:
Size [0.05 - Enter the ramp-down time, that is, the
related 3600 s] deceleration time from the synchronous
*
motor speed n
down time such that no overvoltage occurs
in the inverter due to regenerative operation
of the motor, and such that the generated
current does not exceed the current limit set
in parameter 4-18 Current Limit. The value
0.00 corresponds to 0.01 s in speed mode.

4.4.4 3-5* Ramp 2
This parameter group configures ramp 2 parameters.
3-50 Ramp 2 Type
Option: Function:
Select the ramp type, depending on
requirements for acceleration/deceleration. A
linear ramp gives constant acceleration during
ramping. A sine 2 ramp gives non-linear
acceleration.
[0] Linear

[2] Sine 2 S-ramp based on the values set in
Ramp parameter 3-41 Ramp 1 Ramp Up Time and
parameter 3-42 Ramp 1 Ramp Down Time.

Range: Function:
Size [0.05 - Enter the ramp-up time, which is the
related 3600 s] acceleration time from 0 RPM to the rated

motor speed n
that the output current does not exceed the
current limit in parameter 4-18 Current Limit
during ramping. The value 0.00 corresponds
