Parameters
(F) Setting of acceleration/deceleration time and acceleration/deceleration pattern
FR-A800
5 - 243
Acceleration time setting (Pr. 7, Pr. 20)
●
Use Pr. 7 "Acceleration time" to set the acceleration time required to reach Pr. 20 "Acceleration/
deceleration reference frequency" from stop status.
●
Set the acceleration time according to the following formula.
Acceleration time setting
=
Pr. 20
×
Acceleration time from stop status to maximum frequency
(Maximum frequency – Pr. 13)
Example
For example, the following calculation is performed to find the setting value for Pr. 7 when increas-
ing the output frequency to the maximum frequency of 50 Hz in 10 s with Pr. 20 = "60 Hz (initial
value)" and Pr. 13 = "0.5 Hz".
Pr. 7 = 60 Hz × 10 s / (50 Hz - 0.5 Hz)
≈
12.1 s
