Notes:
During stall prevention the actual acceleration and deceleration time is based on preset acceleration /
deceleration time + S curve time.
To disabled S curve function set parameter 11-04~11-07 to 0.
Accelerating time = Accelerating time 1 (or 2) + (11-04) + (11-05)

Deceleration time = Deceleration time 1 (or 2) + (11-06) + (11-07)

These parameters allow “skipping over” of certain frequencies that can cause unstable operation due to
resonance within certain applications.
Note:
Prohibit any operation within the skip frequency range. During acceleration and deceleration the frequency
is continuous without skipping the jump frequency.
To enable skip frequency 1
– 3 (11-08 – 11-10) set the frequency to a value greater than 0.0 Hz.
Use the skip frequency range (11-11) to create a skip frequency bandwidth. Refer to figure 4.3.15.
