Setting 0: 0.01 s Units
The accel/decel. times are set in 0.01 s units. The setting range will be 0.00 to 600.00 s. If any of the parameters C1-01 to
C1-09 is set to 600.1 seconds or more, then C1-10 cannot be set to 0.
Setting 1: 0.1 s Units
The accel/decel. times are set in 0.1 s units. The setting range will be 0.0 to 6000.0 s.
■
C1-11: Accel/Decel Switching Frequency
Sets the switching frequency for automation accel/decel. time change over.
Refer to Switching Accel/decel Times by a
Note:
Setting C1-11 to 0.0 Hz disables this function.
◆
C2: S-Curve Characteristics
Use S-curve characteristics to smooth acceleration and deceleration and to minimize abrupt shock to the load. Set S-
curve characteristic time during acceleration/deceleration at start and acceleration/deceleration at stop. If a STo fault
(Hunting Detection 2) occurs when starting a PM motor, try increasing the value set to C2-01.
■
C2-01 to C2-04: S-Curve Characteristics
C2-01 through C2-04 set separate S-curves for each section of the acceleration or deceleration.
explains how S-curves are applied.

Figure 5.24 S-Curve Timing Diagram - FWD/REV Operation
Setting the S-curve will increase the acceleration and deceleration times.
Actual accel time = accel time s (C2-01 + C2-02)/2
Actual decel time = decel time s (C2-03 + C2-04)/2
