Acceleration/Deceleration Pattern - Mitsubishi Electric FR-A820-00046 Instruction Manual

(F) Setting of acceleration/deceleration time and acceleration/deceleration pattern
5.8.2

Acceleration/deceleration pattern

The acceleration/deceleration pattern can be set according to the application.
In addition, the backlash measures that stop acceleration/deceleration by the frequency or time set
with parameters at acceleration/deceleration can be set.

Linear acceleration/deceleration (Pr. 29 = "0" initial value)
When the frequency is changed for acceleration, deceleration, etc. during inverter operation, the out-
put frequency is changed linearly (linear acceleration/deceleration) to reach the set frequency with-
out straining the motor and inverter. Linear acceleration/deceleration has a uniform frequency/time
slope.

Set the stopping frequency and time
during backlash measures.
Valid by backlash measures
(Pr. 29 = "3").
Set the time for drawing the S-pattern
from acceleration/deceleration start to
linear acceleration as a ratio (%) of
acceleration/deceleration time (Pr. 7,
Pr. 8, etc.).
The acceleration/deceleration curve
can be switched by the X20 signal.
Valid by S-pattern acceleration/
deceleration C (Pr. 29 = "4").
Set the time required for acceleration
(S-pattern) of S-pattern acceleration/
deceleration.
Valid by S-pattern acceleration/
deceleration D (Pr. 29 = "5").
