multi- stage instruction is relative value, which is the percentage of relative maximum frequency F0.07. The
positive or negative of the parameter determines the running direction, if it is negative, it means the inverter
runs in the opposite direction.
4 X terminals are selected as the signal input terminals K1~K4 for multi-segment frequency designation,
and they are sequentially formed into 4-bit binary numbers: 1 means that the setting function of the X terminal
is valid, and 0 means that the setting function of the X terminal is invalid.
According to the state, it can be combined into 15 states, and these 15 states correspond to 15 command
setting values. The details are shown in the following table:

8.2.5 Set main frequency through simple PLC
When the simple PLC is used as the main frequency, set FA.00 to select the operation mode of the simple
PLC, whether to remember the operating stage and operating frequency of the PLC before power failure after
power failure or shutdown:
When the operating frequency of the simple PLC is selected to be given by the multi-segment frequency
N (the unit digit of FA.01 is 0), it is necessary to set the parameter FA.31～FA.45, FA.01～FA.30 set the running
time, acceleration and deceleration time and running direction of each segment;
