Toshiba Tosvert VF-S15 Instruction Manual page 171

Note 1: The deceleration time and the acceleration time when f302=3 or 4 depend on the setting of f317
and that of f318, respectively.
Note 2: Even if these functions are used, a motor may coast according to load conditions.
In this case, use the auto-restart function (f301) for the smooth restart after power supply is restored .
Note 3: Jog run function doesn't operate at synchronized acceleration/deceleration.

●The time for which the operation of the motor
can be continued depends on the machine
inertia and load conditions. Before using this
function, therefore, perform verification tests.
●Use with the retry function allows the motor to
be restarted automatically without being
brought to an abnormal stop.
