DETAILED PARAMETER DESCRIPTION
P0104 - S Ramp
Adjustable range: 0.0 to 100.0 % Factory setting: 0.0 %
Acesso: Menu → Configurations → Ramps
Description:
This parameter allows the acceleration and deceleration ramps to have a non-linear profile, similar to an “S”.
See Figure 5.3 on page 5-12 .

Setting 0.0 % means inactive function. In this case, only the linear ramp will be used.
S ramp reduces mechanical shocks during accelerations or decelerations.
P0119 - Reactive power reference for the power factor control
Adjustable range: -99.99 to 99.99 % Factory setting: 0.00 %
Acesso: Menu → Configurations → Control
Description:
It defines the external reference for the reactive current of the synchronous motor.
For negative values, the reference of the reactive current will be capacitive. For positive values, it will be
inductive.
