■ Guideline for the setting
The criteria of acceleration time and deceleration time is the value of <FH: Maximum frequency>.
Note that it is not the value of <UL: Upper limit frequency>.
You can use <F519: Unit of Acc/Dec time> to switch the unit of setting time between 0.1s and 0.01s.
With acceleration/deceleration time set to 0.0 second, the unit of 0.05 second is used internally for
<F519> is "2: 0.1s unit" (default setting), and the unit of 0.01 second for <F519> is "1: 0.01s unit".
Memo
• When you set a time shorter than the optimum acceleration/deceleration time determined by
the load condition, the stall prevention action may cause the acceleration/deceleration time to
be longer than the setting value.
• If you set a further shorter acceleration/deceleration time, the inverter may stop due to an
overcurrent trip or overvoltage trip for protection. For details, refer to "Chapter 13".
• The stop methods of the motor are the deceleration stop by <dEC: Deceleration time 1> or the
coast stop. For details, refer to [6. 3. 1].
• You can set four types of options for each acceleration and deceleration time. For Acceleration
time 2 through 4 and Deceleration time 2 through 4, refer to [6. 27. 2].
