Acceleration time: refers to the time required that the inverter accelerates from 0Hz to maximum output frequency (F0.08)
;
Deceleration time: refers to the time required that the inverter decelerates from maximum output frequency (F0.08) to
0Hz.
Actual deceleration time = preset acceleration and deceleration time × (set frequency/maximum frequency)
Acceleration and deceleration time schematic that the set frequency is less than the maximum frequency.
VFR-013 series inverter has two groups of deceleration time.
First group: F0.05, F0.06; second group: F7.03, F7.04
Acceleration and deceleration time can be selected by using the multi-function input terminals (F1 group) . The fault value
of acceleration and deceleration time is the first group.

Carrier frequency pair impact diagram
The advantage of high carrier frequency: there are more ideal current waveform, less current harmonics and less motor
noise.
The disadvantage of high carrier frequency: switching loss increases, the inverter temperature increases, the inverter
output is affected, the inverter derates under high carrier frequency; the leakage current of the inverter increases, the
electromagnetic interference on external increases.
The low carrier frequency has contrary the case described above, the too low carrier frequency will cause the instability of
low frequency operation, the torque reduction even oscillation.
The inverter has been set reasonably before leaving factory. Under normal circumstances, user does not need change the
parameters.
If the frequency that user uses is more than the default carrier frequency, the derating is required, derating 20%. each

★
Maximum output frequency is used to set the maximum output frequency of inverter. User shall note that it is the basis of
frequency setting, as well as the basis for the speed of acceleration and deceleration.
