C1-14

RUN

Accel/Decel Rate Frequency

Sets the base frequency used to calculate acceleration and deceleration rates.

0.0 Hz

(0.0 - 590.0 Hz)

The acceleration and deceleration rates set in C1-01 to C1-09 [Acceleration/Deceleration Times 1 to 4, Fast Stop Time] will change when the value of C1-14 changes.

  • When C1-14 = 0.0 Hz

    • C1-01, C1-03, C1-05, C1-07 [Acceleration Times 1 to 4]: Time to accelerate from 0 Hz to E1-04 [Maximum Output Frequency]

    • C1-02, C1-04, C1-06, C1-08 [Deceleration Times 1 to 4], C1-09 [Fast Stop Time]: Time to decelerate from E1-04 to 0 Hz.

    Figure 1. 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. Example 2: Acceleration/Deceleration Rate (When C1-14 = 40 Hz, E1-04 = 60 Hz, and the Frequency Reference is 60 Hz)
    Figure 3. Example 3: Acceleration/Deceleration Rate (When C1-14 = 80 Hz, E1-04 = 60 Hz, and the Frequency Reference is 60 Hz)
Note:

  • Figure 1 to 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.
