During operation, the LED display content is set by F0 - 37 / F0 - 38.
When shutting down, the LED display content is set by F0 - 37 / F0 - 38.

This function is only valid when the frequency source is set digitally.
0: “no memory" means that after the frequency inverter is shut down, the digital set frequency value is restored
to F0 - 09 (preset frequency) values, keyboard ▲ and ▼ keys or frequency correction by terminals up and down are
cleared.
1: “memory" means that after the frequency inverter is shut down, the digital set frequency will remain the set
frequency at the time of the last shutdown. Frequency correction by keys ▲, ▼ or terminals up and down remains
valid.
F0 - 27 runtime frequency command up / down reference 0

This parameter is valid only if the frequency source is set digitally.
0: the operating frequency is the benchmark.
When the ▲, ▼ keys or terminals up / down of the keyboard are operated, what method is used to correct the
set frequency, that is, the target frequency rate is increased or decreased based on the operating frequency.
1: set frequency as reference.
When the ▲, ▼ keys or terminals up / down of the keyboard are operated, what method is used to correct the
set frequency, that is, the target frequency the rate is increased or decreased based on the set frequency.
The difference between the two settings is obvious when the frequency inverter is in the process of acceleration
and deceleration, that is, if the frequency of operation of the frequency inverter, When the rate is different from the set
frequency, the different choices of this parameter are very different.
F0 - 28 motor selection

HV610 supports the application of time-sharing drive of two motors by frequency inverters. The two motors can
respectively set motor nameplate parameters, independent parameter tuning, select different control modes, and
independently set parameters related to operation performance, etc. The user selects the current motor parameter
group through the F0 - 28 function code, and who can also switch the motor parameters through the digital quantity
input terminal X. When the function code selection conflicts with the terminal selection, the terminal selection shall
prevail
0: motor 1.
The corresponding functional parameter groups of motor parameter group 1 are f1 group and F2 group.
1: motor 2
Motor parameter group 2 corresponds to functional parameter group FB.
F0 – 29 auxiliary frequency source y

When the auxiliary frequency source is given a channel as an independent frequency (i.e. the frequency source
is selected as X to Y switch), its usage is the same as that of the main frequency source X. the usage method can
refer to the relevant description of F0 - 03.
When the auxiliary frequency source is used for superposition and given (i.e. the composite implementation
frequency of the main frequency source X and the auxiliary frequency source Y is given), attention should be paid to:
1. When the auxiliary frequency source is given by numbers, the preset frequency (F0 - 09) does not work, and
the user can select the preset frequency (F0 - 09) through the keyboard ▲, ▼ key (or up and down of multi-function
input terminal) adjusts the frequency directly on the basis of the main given frequency.
2. When the auxiliary frequency source is given by analog input (AI1, AI2, and AI3) or pulse input, the input
setting of 100 % corresponds to the auxiliary frequency source range, which can be set through F0 - 30 and F0 - 31.
3. Frequency source for pulse input timing, similar to analog given. Tips: the selection of the auxiliary frequency
source Y and the selection of the main frequency source X cannot be set to the same channel, i.e. F0 - 03 and F0 -
29 should not be set to the same value, otherwise it will easily cause confusion.
