Setting of acceleration/deceleration time and acceleration/ deceleration pattern
(2) 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.
Parameter
Number
Name Setting Range Description
61 Reference current
0 to 500A
For example, when the motor and inverter are different in capacity,
set the rated motor current value.
Set reference current (A) of the stall prevention operation level
during acceleration/deceleration.
9999 (initial value) The rated inverter current is defined as reference.
62
63
Reference value at
acceleration
Reference value at
deceleration
0 to 200%
Set when it is desired to change the reference level of acceleration
and deceleration.
Set the stall prevention operation level (ratio to the current value of
Pr. 61) during acceleration/deceleration.
9999 (initial value)
Stall prevention operation level is 150% for the shortest acceleration/
deceleration.
REMARKS
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.
