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

Note:
•
to
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.
