Parameter
Adjustment of shortest acceleration/deceleration mode (Pr. 61 to Pr. 63)
By setting the adjustment parameters Pr. 61 and Pr. 63, the application range can be made
wider.

NOTES
Pr. 61 to Pr. 63 are invalid when real sensorless vector control or vector control is selected in
the shortest acceleration/deceleration mode.
Under advanced magnetic flux vector control, real sensorless vector control or vector control
the elevator mode can not be activated.
Since the Pr. 61 to Pr. 63 settings automatically return to the initial value (9999) if the Pr. 292
setting is changed, set Pr. 292 first when you need to set Pr. 61 to Pr. 63.

Description
For example, when the motor and inverter are different
0–500A
in capacity, setthe rated motor current value.
Shortest acceleration/deceleration: Set reference cur-
rent (A) of the stall prevention operation level during
acceleration/deceleration.
0–3600A
Optimum acceleration/deceleration: Set reference cur-
rent (A) of the optimum current during acceleration/
deceleration.
The rated inverter current is defined as reference.
Set when it is desired to change the reference level of
acceleration and deceleration.
Shortest acceleration/deceleration: Set the stall pre-
vention operation level (ratio to the current value of Pr.
0–200%
61) during acceleration/deceleration.
Shortest acceleration/deceleration: Set the optimum
current level (ratio to the current value of Pr. 61) dur-
ing acceleration/deceleration.
Shortest acceleration/deceleration: The 150% value
during shortest acceleration/deceleration is judged as
the stall prevention operation level.
Optimum acceleration/deceleration: 100% is the opti-
mum value
