Application Guide | iC2-Micro Frequency Converters
Use this parameter to select the ramp type, depending on requirements for acceleration and deceleration. A linear ramp provides
constant acceleration during ramping. Sine Ramp and Sine 2 Ramp provide non-linear acceleration.

values set in P 5.5.4.2 Ramp 1 Accel. Time and P 5.5.4.3 Ramp 1
Decel. Time.
P 5.5.4.2 Ramp 1 Accel. Time
Use this parameter to enter acceleration time. The values range from 0 Hz to the motor frequency defined in P 4.2.2.4 Nominal
Frequency. Select a ramp up time such that the output current does not exceed the current limit in P 2.7.1 Output Current Limit % during
ramping.
Default value: Size Related Parameter type: Range (0.01–3600.00)

P 5.5.4.3 Ramp 1 Decel. Time
Use this parameter to enter the deceleration time. The values range from the motor frequency defined in P 4.2.2.4 Nominal Frequency to
0 Hz. Select a ramp 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 P 2.7.1 Output Current Limit %.

P 5.5.4.8 Ramp 2 Type Selector
Use this parameter to select the ramp type, depending on requirements for acceleration and deceleration. A linear ramp provides
constant acceleration during ramping. Sine Ramp and Sine 2 Ramp provide non-linear acceleration.
