Acceleration and Deceleration Characteristics
6-
19
* The setting range for acceleration/deceleration times depends on the setting of C1-10 (Acceleration/deceleration Time Setting Unit). If C1-10 is set to 0,
the setting range is 0.00 to 600.00 (s).
Setting Acceleration and Deceleration Time Units
Set the acceleration/deceleration time units using C1-10. Constant C1-10 is set to 1 at the factory.
Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal
Commands
Using the Inverter, you can set four acceleration times and four deceleration times. When the multi-function
input terminals (H1-
) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/decel-
eration time selection 2), you can switch the acceleration/deceleration time even during operation by combin-
ing the ON/OFF status of the terminals.
The following table shows the acceleration/deceleration time switching combinations.

Accel/decel
time switch-
ing frequency
Sets the frequency for automatic
acceleration/deceleration switching.
Below set frequency: Accel/decel
time 4
Above set frequency: Accel/decel
time 1
The multi-function input “accel/
decel time 1” or “accel/decel time
2” take priority.

at accelera-
tion start
All sections of the S-curve charac-
teristic time are set in seconds units.
When the S-curve characteristic
time is set, the accel/decel times
will increase by only half of the S-
curve characteristic times at start
and end.
