Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal

Commands

Four different acceleration times and deceleration times can be set. When the multi-function input terminals

(H1-) are set to 7 (acceleration/deceleration time selection 1) and 1A (acceleration/deceleration time

selection 2), you can switch the acceleration/deceleration time even during operation by combining the ON/

OFF status of the terminals.

The following table shows the acceleration/deceleration time switching combinations.

Switching Acceleration and Deceleration Times Using a Frequency Level

The acceleration/deceleration times can be switched over automatically at a certain output frequency which

can be set in parameter C1-11.

Fig 6.22 shows the working principle of the function.

Set C1-11 to a value other than 0.0 Hz. If C1-11 is set to 0.0 Hz, the function will be disabled.

When output frequency ≥ C1-11, acceleration and deceleration are performed using

Acceleration/deceleration Time 1 (C1-01, C1-02).

When output frequency < C1-11, acceleration and deceleration are performed using

Acceleration/deceleration Time 4 (C1-07, C1-08).
