F0 - 13 acceleration and deceleration time reference
frequency
0
～
2 [0]
0: the reference frequency is the maximum frequency (F0 - 16)
1: set the frequency at the reference frequency.
When F0 - 13 is selected as 1, the acceleration and deceleration time is related to the set frequency. If the set
frequency changes frequently, the acceleration of the motor will change. Attention should be paid when applying.
2: 100 Hz at reference frequency.
F0 - 14 shutdown mode
0
～
1 [0]
0: after the deceleration
Stop command is valid, the frequency inverter will reduce the output frequency according to the deceleration
time, and stop after the frequency is reduced to 0.
1: after the free
Stop command is valid, the frequency inverter will terminate the output immediately. At this time, the motor will
stop freely according to the mechanical inertia.
F0 - 15 droop control rate
0
～
10.00hz [0.00hz]
The droop rate allows for a slight speed difference between the master station and the slave station, thus
avoiding the rush between them. The default value for this parameter is 0.
Only when the main engine and the slave engine adopt the speed control mode will the droop rate need to be
adjusted. For each transmission process, the appropriate droop rate needs to be gradually found in practice. It is
recommended not to set F0 - 15 too large, otherwise the steady-state speed will drop significantly when the load is
large. Both the master and slave must set the droop rate.
Droop speed = synchronous frequency * output torque * (droop rate / 10)
For example: F0 - 15 = 1.00
50 Hz synchronous frequency rate, 50 % output torque, real frequency rate of frequency changer = 50 Hz – 50 *
(50 %) (1.00/10) = 47.5hz
F0 - 16 maximum frequencies

～
500.00hz [50.00hz]
The analog input, pulse input (X5), multi-segment instruction, etc. are all 100.0 % of the respective calibration of
F0 - 16 when they are used as frequency sources.
F0 - 17 upper frequency sources
0
～
5 [0]
0: set by F0 - 18.
1: set by analog AI1.
2: set by analog AI2.
3: set by analog AI3.
4: set by digital pulse quantity X5.
5: through communication settings.
F0 - 18 upper limit frequency
Upper limit frequency ~ maximum frequency [ 50.00 Hz ]
F0 - 19 upper frequency offset
Upper limit frequency ~ maximum frequency [ 50.00 Hz ]
When the upper limit frequency source is set to analog quantity or pulse setting, F0 - 19 is used as the offset
amount of the set value, and the offset frequency is superposed with the upper limit frequency value set by F0 - 17 as
the set value of the final upper limit frequency.
