Description of Parameters

Figure 8-42: Acceleration/Deceleration (S-shaped)

498 Start pulse memory 3 (P1.2.24)

Giving a value to this parameter determines if the present RUN status is copied when

the control place is changed from A to B or vice versa.

0 The RUN status is not copied

1 The RUN status is copied

In order for this parameter to have effect, ID300 and ID363 must have been set the

value 3.

500 Acceleration/Deceleration

ramp 1 shape

234567 (P1.4.1)

501 Acceleration/Deceleration

ramp 2 shape

234567 (P1.4.2)

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 which causes

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

signal.

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

acceleration/deceleration. The acceleration time is determined with ID103 and ID104

(ID502 and ID503).

502 Acceleration time 2 234567 (P1.4.3)

503 Deceleration time 2 234567 (P1.4.4)

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

from the zero frequency to the set maximum frequency (ID102). 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 signal DIN3

(ID301).
