3-50 Ramp 2 Type
Default value:
[0] Linear
Setup:
All setups
Data type:
Uint8
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.

Enter the ramp-up time, which is the acceleration time from 0 Hz to the rated motor speed n
output current does not exceed the current limit in parameter 4-18 Current Limit during ramping. See ramp-down time in parameter
3-52 Ramp 2 Ramp Down Time.
3-52 Ramp 2 Ramp Down Time
Default value:
Size related
Setup:
All setups
Data type:
Uint32
Enter the ramp-down time, which is the deceleration time from the rated motor speed n
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 3-51 Ramp 2 Ramp Up Time.
