Parameters
(F) Setting of acceleration/deceleration time and acceleration/deceleration pattern
FR-A800
5 - 259
Shortest and optimum acceleration/deceleration adjustment (Pr. 61 to Pr. 63)
The application range can be expanded by setting the parameters for adjustment of Pr. 61 to Pr. 3.
The setting range for the FR-A820-03160(55K) or lower and FR-A840-01800(55K) or lower.
The setting range for the FR-A820-03800(75K) or higher and FR-A840-02160(75K) or higher.

Description
61
Reference
current
Set the rated motor current value such as when the motor capacity
and inverter capacity differ.
Shortest acceleration/deceleration: Set the reference current (A) of the
stall prevention operation level during acceleration/deceleration.
Optimum acceleration/deceleration: Set the reference current (A) of
the optimum current during acceleration/deceleration.
0 to 3600 A
9999 (initial value)
The rated inverter current value is the reference.
62
Reference value
at acceleration
Reference value
at deceleration
0 to 400%
Set this when changing the reference level of acceleration and
deceleration.
Shortest acceleration/deceleration: Set the stall prevention operation
level (percentage of current value of Pr. 61) during acceleration/
deceleration.
Optimum acceleration/deceleration: Set the optimum current level
(percentage of current value of Pr. 61) during acceleration/
deceleration.
63
9999 (initial value)
Shortest acceleration/deceleration: Stall prevention operation level is
150% for the shortest acceleration/deceleration.
Optimum acceleration/deceleration: 100% as the optimum value.
NOTES
When Real sensorless vector control or vector control is selected with the shortest acceleration/
deceleration, Pr. 61 to Pr. 63 are invalid.
Even if Pr. 61 to Pr. 63 are set once, changing the setting to other than the shortest acceleration/
deceleration (Pr. 292
≠
"1 or 11") automatically resets them to the initial setting (9999). Set Pr. 61 to
Pr. 63 after setting Pr. 292.
