2.5.5 Shortest acceleration/deceleration and optimum acceleration/deceleration
(automatic acceleration/deceleration) [Pr. 61 to 63, 292, 293]
The inverter operates in the same conditions as when
appropriate values are set in each parameter even if
acceleration/deceleration time and V/F pattern are not set. This
function is useful when you just want to operate, etc. without
fine parameter setting.
Even if automatic acceleration/deceleration mode is selected,
inputting the JOG signal (Jog operation) or RT signal (second
function selection) or X9 signal (third function selection) during

an inverter stop will switch to the normal operation and give
priority to Jog operation or second and third function selection.
Note that JOG and RT signal input is invalid even if JOG signal
and RT signal are input during operation in automatic
acceleration/deceleration mode.
When PID control or load torque high speed frequency control
is selected, optimum acceleration/deceleration is invalid.
