AC300 Series Vector Control Inverter Manual
7: Terminal UP/DW control
The set frequency is controlled by the control terminal to increase and decrease, and the "frequency increment (UP)"
terminal and the "frequency decrement (DW)" terminal and (COM) of the multi-function terminal (X1 to X10) are
controlled to be turned on and off. For details, see the parameter description of the [F02.00~F02.09] terminal.
8: PID control given
When [F00.03] or [F00.04] selects the channel, the inverter running mode is process PID control, the set frequency is
the output after PID action, the PID control gives the quantitative and feedback quantity and other control parameters.
The process PID controls the parameter group "F11".
The current set value of the parameter [F11.01] can be quickly modified by selecting the [F04.09] LED single digit
up/down key. The parameter value power-down storage and up/down key action limit selection are detailed in the
parameter [F04.09 ].
The status and characteristics of the PID control can be changed through the multi-function input terminal. For details,
see the parameter description of the [F02.00~F02.09] terminal.
9: Program control (PLC) given
The set frequency and the running direction of the inverter are controlled by the process of the simple PLC inside the
inverter, and the process can control up to 15 speeds. For details, see parameter "F12" multi-speed, PLC function and
swing frequency parameter group;
If a speed running time is set to "0", the program speed is skipped when the program is running, which makes it easy
to set the speed of the program running. When the parameter [F00.16] LED hundred bit is set to "0", the frequency
control direction is invalid or [F00.16] LED tens place is set to "1", when reverse rotation is prohibited, if any speed
running command direction setting In order to reverse, the inverter runs at a frequency of 0.00 Hz at this speed.
Both the program operation and the multi-speed operation are to realize the variable speed operation of the inverter
according to a certain rule. In multi-speed operation, multi-speed switching and running direction change are realized by
different combinations of "multi-speed control terminals 1-4" and (COM) defined in "multi-function input terminal". The
program running function can not only define the multi-segment frequency of one cycle in the function parameters, but
also the time, direction, acceleration/deceleration time and cycle mode of multi-segment frequency operation can also
be defined in the function parameters. The multi-speed control terminal can be defined by any multi-function terminal.
For details, refer to the parameter description of the [F02.00~F02.09] terminal.
10: Optional card
The setting frequency is given and modified by the external optional card communication. For the installation method
and parameter setting of the optional card, please refer to the instruction manual of the same box with the optional card.
11: Multi-steps speed given
The set frequency is selected by the "multi-speed terminal". If the frequency channels A and B are not selected for
the multi-speed reference, the multi-speed terminal has a higher priority to switch the frequency to the multi-speed
reference; if A, B, When a multi-speed speed reference is selected for one channel, the combination of frequency
source settings is performed. When the multi-speed terminal is invalid, the multi-speed speed is given as zero. For the
"multi-speed terminal", please refer to the parameter description of the [F02.00~F02.09] terminal.
F00.05 Frequency channel B reference source

of the frequency reference channel A is the maximum frequency [F00.09].

Maximum frequency
F00.06 Frequency given source selection
Uses for selecting frequency given A channel and B channel combination.
0: Channel A is valid only for channel A[F00.03], and channel B[F00.04] is invalid.
1: Channel B is valid only for channel B[F00.04], and channel A[F00.03] is invalid.
2: Channel A+channel B Channel A [F00.03] sets the frequency plus channel B[F00.04] setting frequency, and
the sum of the two is the frequency set by the inverter.
3: Channel A-channel B Channel A[F00.03] sets the frequency minus the channel B[F00.04] setting frequency.
The difference between the two is the frequency set by the inverter. This method may generate a negative frequency. .
Whether the output is valid when a negative frequency is generated is determined by the [F00.16] setting.
4: Maximum value of channel A and channel B Channel A [F00.03] set frequency and channel B [F00.04] set
frequency to take the maximum value, the larger is the inverter set frequency.
5: Minimum value of channel A and channel B Channel A [F00.03] set frequency and channel B [F00.04] set
frequency to take the minimum value, the smaller is the inverter set frequency.
Notes:
1. When the jog run command is valid, the jog set frequency is used as the inverter set frequency.
2. No multi-speed speed is selected for channels A and B. If multi-speed terminal selection is valid, the
corresponding frequency is selected as the inverter setting frequency.
3. When the given sources selected by channels A and B are the same, no superposition calculation is
performed, and the given source frequency of channel A is used as the set frequency of the inverter.
4. Frequency given source priority: From high to low, it is jog running frequency setting, multi-speed speed
setting, running command bundling given frequency, frequency given source channel.
5. If the rotation direction selection [F00.16] is set to reverse prohibition, the inverter will output a
frequency of 0.00Hz regardless of the value of the frequency control direction selection and the
frequency calculation result is negative.
Tips:
The given frequency after the combination of frequency reference channel A and frequency reference

channel B is still limited by the upper limit frequency and lower limit frequency.
F00.07 Running Command Binding Setting range: 0000～DDDD
When this parameter is valid, it is used to set the channel source frequency channel for each running command
channel. When the command source has a bundled frequency source, the set frequency is given by the frequency
source bundled by [F00.07], and the set frequency obtained by [F00.03~F00.06] will no longer be used. Effective, but
