Total acceleration and deceleration time when the S curve is used:
Accelerating time = Accelerating time 1 (or 2) + (11-04) + (11-05)
2
Deceleration time = Deceleration time 1 (or 2) + (11-06) + (11-07)

These parameters allow “jumping over” certain frequencies that can cause unstable operation due to mechanical
resonance in certain applications.
Note:
Prohibit any operation within the jump frequency range. During acceleration and deceleration the frequency
is continuous without skipping the jump frequency.
To enable jump frequency 1
– 3 (11-08 – 11-10) set the frequency to a value greater than 0.0 Hz.
Use the jump frequency width (11-11) to create a jump frequency range. Refer to Figure 4.3.86.

Figure 4.3.86 Jump frequency operation
Jump frequency via Analog Input.
Set parameter 04-05 (AI2 function selection) to 9 (frequency jump setting 4) to control the jump frequency via
analog input AI2.
Note:
When jump frequency overlap the sum of the overlapped jump frequencies will be used as the jump
frequency range. Refer to Figure 4.3.87.
