P7.12 248 Ramp 2 Shape 1, 2, 3, 4 RW

The start and end of the acceleration and deceleration ramps can be smoothed with

these parameters. Setting a value of 0.0 gives a linear ramp shape that causes

acceleration and deceleration to react immediately to the changes in the reference

signal.

Setting a value from 0.1 to 10 seconds for this parameter produces an S-shaped

acceleration/deceleration. The acceleration time is determined with P1.3 and P1.4 or

P7.13 and P7.14.

P7.13 249 Accel Time 2 1, 2, 3, 4 RW

P7.14 250 Decel Time 2 1, 2, 3, 4 RW

These values correspond to the time required for the output frequency to accelerate

from the zero frequency to the set maximum frequency (P1.2). These parameters

provide the possibility to set two different acceleration/deceleration time sets for

one application. The active set can be selected with the programmable digital input.
