5 Programming cases

5.1 For PLC card digital input/output terminals

Requirement: When the PS1 terminal of the PLC card has an input signal, the RO1 terminal of
the VFD has output. When both the S2 and S3 terminals of the VFD have an input signal, the
RO2 terminal of the VFD has output.
Implementing method: The LD is used for programming.
VFD function code setting: P06.03=44 (RO1 is given by the PLC card) and P06.04=45 (RO2 is
given by the PLC card)
The following figure shows the code example and online debugging result:

5.2 For terminal-based running/fault control

Requirement: When the PS5 terminal on the PLC card has an input signal, the VFD runs
forward. When the PS6 terminal on the PLC card has an input signal, the VFD runs reversely.
When a fault occurs, the fault can be reset through input to the S3 terminal on the VFD. When
the S4 terminal on the VFD has input, external PLC fault 5 occurs.
Implementing method: The LD is used for programming. The programming logic is as follows:
Run forward=PS5, Run reversely=(!PS5)&PS6, Decelerate to stop=(!PS5)&(!PS6), External
fault 5=S4, Fault reset=(!S4)&S3
VFD function code setting: P00.01=2, P00.02=4, P00.06=a value ensuring the set frequency
is not 0
