Figure 2.47 Example 1: Acceleration/Deceleration Rate (When C1-14 = 0 Hz, E1-04 = 60 Hz, and the Frequency Reference is
60 Hz)
• When C1-14 ≠ 0.0 Hz
– C1-01, C1-03, C1-05, C1-07: Time to accelerate from 0 Hz to C1-14
– C1-02, C1-04, C1-06, C1-08, C1-09: Time to decelerate from C1-14 to 0 Hz
Figure 2.48 Example 2: Acceleration/Deceleration Rate (When C1-14 = 40 Hz, E1-04 = 60 Hz, and the Frequency Reference
is 60 Hz)
Figure 2.49 Example 3: Acceleration/Deceleration Rate (When C1-14 = 80 Hz, E1-04 = 60 Hz, and the Frequency Reference
is 60 Hz)
Note:
• Figure 2.47 to Figure 2.49 show the accel/decel times when C2-01 to C2-04 [S-Curve Times @ Start/End of Accel/Decel] = 0.00 s.
• When L3-01 ≠ 0 [Stall Prevention during Accel≠ Disabled], Stall Prevention could cause the acceleration time to be longer than the set
value.
• When L3-04 ≠ 0 [Stall Prevention during Decel ≠ Disabled], Stall Prevention could cause the deceleration time to be longer than the set
value.
◆ C2: S-Curve Characteristics
Use S-curve characteristics to smooth acceleration and deceleration and to minimize abrupt shock to the load.
