F8-04 Deceleration time 2 0.0–6500.0s Model dependent
F8-05 Acceleration time 3 0.0–6500.0s Model dependent
F8-06 Deceleration time 3 0.0–6500.0s Model dependent
F8-07 Acceleration time 4 0.0–500.0s Model dependent
F8-08 Deceleration time 4 0.0–6500.0s Model dependent
The MD380 provides a total of four groups of acceleration/deceleration time, that is,
the preceding three groups and the group defined by F0-17 and F0-18. Definitions of
four groups are completely the same. You can switch over between the four groups of
acceleration/deceleration time through different state combinations of DI terminals. For more
details, see the descriptions of F4-01 to F4-05.
Function Code Parameter Name Setting Range Default
F8-09 Jump frequency 1 0.00 Hz to maximum frequency 0.00 Hz
F8-10 Jump frequency 2 0.00 Hz to maximum frequency 0.00 Hz
F8-11 Frequency jump amplitude 0.00 Hz to maximum frequency 0.00 Hz
If the set frequency is within the frequency jump range, the actual running frequency is the
jump frequency close to the set frequency. Setting the jump frequency helps to avoid the
mechanical resonance point of the load.
The MD380 supports two jump frequencies. If both are set to 0, the frequency jump function
is disabled. The principle of the jump frequencies and jump amplitude is shown in the
following gure.
