TD20 Series VFD Function Parameters
-27-
Detailed instruction of parameters
The VFD runs at multi-step speed mode when P00.06=6
or P00.07=6. Set P05 to select the current running step,
and set P10 to select the current running frequency.
The multi-step speed has the priority when P00.06 or
P00.07 does not equal to 6, but the setting stage can
only be the 1–15 stage. The setting stage is 1–15 if
P00.06 or P00.07 equals to 6.
7: PID control setting
The running mode of the VFD is process PID control
when P00.06=7 or P00.07=7. It is necessary to set P09.
The running frequency of the VFD is the value after PID
effect. See P09 for the detailed information of the preset
source, preset value and feedback source of PID.
8: MODBUS communication setting
The frequency is set by MODBUS communication. See
P14 for detailed information.
9–11: Reserved
Note: A frequency and B frequency can not set as the
same frequency given method.
B frequency
command
reference
selection
0: Maximum output frequency, 100% of B frequency
setting corresponds to the maximum output frequency
1: A frequency command, 100% of B frequency setting
corresponds to the maximum output frequency. Select
this setting if it needs to adjust on the base of A
frequency command.
Combination
of the setting
source
0: A, the current frequency setting is A frequency
command
1: B, the current frequency setting is B frequency
command
2: A+B, the current frequency setting is A frequency
command + B frequency command
3: A-B, the current frequency setting is A frequency
command - B frequency command
4: Max (A, B): The bigger one between A frequency
command and B frequency is the set frequency.
5: Min (A, B): The lower one between A frequency
command and B frequency is the set frequency.
Note: The combination manner can be shifted by P05
(terminal function)
