When the set frequency is equal to the maximum frequency, the actual Acceleration/Deceleration time
are equal to the set Acceleration/De celeration time.
When the set frequency is less than the maximum frequency, the actual Acceleration/Deceleration time
are less than the set Acceleration/Deceleration time.
Actual Accel eration /Decelerati on time = set Acceleration/Decelerat ion time (set frequency/max.
frequency)
DZB200&300 series inverter ha s 2 groups of Acceleration/Decelerat ion time.
1st group: F0.08, F0.09;
2nd group: F4.00, F4.01;
The Acceleration /Deceleration time can be chosen through multifunction digital input terminal (F2 Group).

0: Operating at default direction. When the inverter is power connected, it operates at the ac tual direction.
1: Operating at reverse direction. By means of changing the function code, the motor rotati ng direction can
be changed without changing any other parameters, which is equivalent to change the motor rotating
direction by exchanging any two of motor cables (U, V, W).
Note: After the parameters are initialized, the motor operating direction can be restor ed to be its
original state. Be caution to use it in the case that changing motor rotating direction is forbidden after
the system commissioning is completed.
2: Forbid inverse operating. Forbidding inverter inverse operation is sui table to specific application that
inverse operating is forbidden.

This function is mainly used to improve the motor operating noise and inverter interference to external.
The advantages of using high carrier frequency: relatively ideal current wave shape, less harmonic
current wave and low motor noise;
The disadvantages of using high carrier frequency: increased switch loss and inverter temperature rises,
affecting inverter output capacity so that it should be operated at derating under high carrier freque ncy
conditions; in the mean time, inverter leaka ge current and its e lectromagnetic interference to external are
increa sed.
The situations of using low carrier frequency is on the contrary. Too low carrier frequency can c ause
operation unstable, torque reduced and even oscillation at low frequency.
When inverter is fact ory released, its ca rrier frequency has been set properly. Generally the user does
not need to modify this parameter.
