Basic Parameters; Setting Acceleration/Deceleration Time - Toshiba TOSVERT VF-S9 Instruction Manual

5. Basic parameters

Before you operate the inverter, the parameters that you must first program are the basic parameters.

Setting acceleration/deceleration time

• Function
1) For acceleration time
0Hz to maximum frequency
2) For deceleration time
maximum frequency
5.1.1 Automatic acceleration/deceleration
This automatically adjusts acceleration and deceleration time in line with load size.
* Automatically adjusts acceleration and deceleration time within the inverter rated current in a range that
goes from 1/8 to infinity of programmed
ginal allowance into consideration.
* Automatically adjusts to the shortest time within 120% of the inverter rated current. It is a value that is ob-
tained attaching importance to acceleration/deceleration time.
