E5 User Manual
Maximum frequency of P10.08 is the maximum allowable output frequency of drive and is
indicated by fmax in the figure.
P10.09 upper limit frequency is the user-defined maximum allowable running frequency
and represented by fH in Fig. 5-4.
P10.10 lower limit frequency is user-defined minimum allowable running frequency and
marked with fL in Fig. 5-4.
In Fig. 5-4, fN represents rated frequency of motor while VN means the rated voltage of
motor.
 ATTENTION:
 Maximum frequency, upper limit frequency and lower limit frequency should be set with care
in accordance with nameplate parameters of motor and operation requirements.
 Jog and motor parameter identification is free from limitations of upper and lower limit
frequency.
 In addition to limitation of upper limit frequency and lower limit frequency, the output
frequency is also subject to limitations of starting frequency, stop DC brake initial frequency,
skip frequency and other parameter settings.
 The rank relation between maximum frequency, upper limit frequency and lower limit
frequency is shown as Fig. 5-4.
 Upper and lower limit frequencies restrict actual output frequency to motor. If command
frequency is higher than upper limit frequency, the running would be at upper limit frequency.
In case command frequency is lower than lower limit frequency, the running should be in
accordance with the setting of P10.11.
Operation when command frequency
P10.11
lower than lower limit frequency
0: Run at lower limit frequency
In case command frequency is lower than lower limit frequency, the running should be at
lower limit frequency.
1: Run at 0Hz
In case the frequency command is lower than lower limit frequency, the running should be at
0Hz.
