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

Name Setting Range Description
61
Reference
current
55K or
lower
0 to 500A
For example, when the motor and inverter are different in capacity,
set the rated motor current value.
Shortest acceleration/deceleration: Set reference current (A) of the
stall prevention operation level during acceleration/deceleration
Optimum acceleration/deceleration: Set reference current (A) of the
optimum current during acceleration/deceleration
75K or
higher
0 to 3600A
9999 (initial value) The rated inverter current is defined as reference.
62
63
Reference value
at acceleration
Reference value
at deceleration
0 to 220%
Set when it is desired to change the reference level of acceleration
and deceleration.
Shortest acceleration/deceleration: Set the stall prevention
operation level (ratio to the current value of Pr. 61 ) during
acceleration/deceleration.
Optimum
acceleration/deceleration: Set the optimum current level
(ratio to the current value of Pr. 61 ) during acceleration/
deceleration.
9999
(initial value)
Shortest acceleration/deceleration: The 150% value during shortest
acceleration/deceleration is judged as the stall prevention operation
level.
Optimum acceleration/deceleration: 100% is the optimum value
REMARKS
⋅ Pr. 61 to Pr. 63 are invalid when Real sensorless vector control or vector control is selected in the shortest acceleration/
deceleration mode.
⋅ 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.
