3-40 Ramp 1 Type
Default value: [0] Linear Parameter type: Option
Setup: All setups Conversion index: –
Data type: Uint8 Change during operation: True
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.
Option Name Description
[0] Linear Linear ramp.
[2] Sine 2 Ramp (Only to be used with speed control
mode.) Sine 2 ramp based on the values
set in parameter 3-41 Ramp 1 Ramp Up
Time and parameter 3-42 Ramp 1 Ramp
Down Time.
3-41 Ramp 1 Ramp Up Time
Default value: Size related Parameter type: Range (0.01–3600.00 s)
Setup: All setups Conversion index: -2
Data type: Uint32 Change during operation: True
Enter the ramp-up time, which is the acceleration time from 0 Hz to the synchronous motor speed n
S
or from 0 Nm to the nominal torque
if torque configuration modes are selected. It is applicable for Ramp 1 to Ramp 4. Select a ramp-up time such that the output current
does not exceed the current limit in parameter 4-18 Current Limitduring ramping. See ramp-down time in parameter 3-42 Ramp 1 Ramp
Down Time.
3-42 Ramp 1 Ramp Down Time
Default value: Size related Parameter type: Range (0.01–3600.00 s)
Setup: All setups Conversion index: -2
Data type: Uint32 Change during operation: True
Enter the ramp-down time, which is the deceleration time from the synchronous motor speed n
s
to 0 Hz or from the nominal torque
to 0 Nm if the torque configuration modes are selected. Select a ramp-down time such that no overvoltage 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 parameter 4-18
Current Limit. See ramp-up time in parameter 3-41 Ramp 1 Ramp Up Time.
4.4.4 3-5* Ramp 2
This parameter group configures ramp 2 parameters.
