4.2.24 Shortest acceleration/deceleration mode (Pr. 60 to Pr. 63)

Pr. 60 "shortest acceleration/deceleration mode"
Pr. 61 "reference current"
Pr. 62 "reference current for acceleration"
Pr. 63 "reference current for deceleration"
The inverter automatically sets the shortest time for acceleration/deceleration for
operation.
• If you do not set the acceleration and deceleration times and V/F pattern, you can run
the inverter as if appropriate values had been set in the corresponding parameters.
This operation mode is useful when you want to operate without fine parameter
setting.
Pr. 61 to Pr. 63 are valid only when Pr. 60 = "1, 2, 11,12".
When the shortest acceleration/deceleration mode is selected, the setting values of
Pr. 7 "acceleration time", Pr. 8 "deceleration time", Pr. 22 "stall prevention operation
level" are made invalid.

enough capability at deceleration..

Set to accelerate/decelerate the
motor in the shortest time.
The inverter makes acceleration/
deceleration in the shortest time
using its full capabilities.
Set "11" or "12" when using
brake resistance and the brake
unit.
