* The setting range for accel/decel times depends on the setting of C1-10 (Accel/Decel Time Setting Units). If C1-10 is set to 0, the setting range is 0.00 to
600.00 (s).
Setting the Units to Express the Acceleration and Deceleration Time
Set the accel/decel time units using C1-10. The default setting for C1-10 is 1.
Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal
Commands
The MxC allows for four separate acceleration times and four separate deceleration times. When the multi-
function input terminals (H1-) are set to 7 (Accel/Decel Time Selection 1) and 1A (Accel/Decel Time
Selection 2), the accel/decel time of the MxC can be changed even while the application is running based on
the terminal switch status.
The following table shows the possible accel/decel time switching combinations.
C2-01
S-Curve Charac-
teristic at Accel
Start
All sections of the S-curve characteristic 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.
