连接数字信号时，注意:

(1)继电器输出PLC与逆变器连接时，应注意接触不良往往会导致逆变器误动作，因此在实际接线时应注意连接是否可靠。

(2)晶体管输出PLC与逆变器连接时，应注意晶体管本身的电压等级及其范围内电流的大小等限制条件，以保证系统的可靠性。

(3)在设计逆变器的输入信号电路时，应尽量避免继电器等感性负载，因为继电器的开闭产生的浪涌电流可能会引起逆变器的错误运行。

(4) PLC输出的开关信号进入逆变器时，有时会发生外部电源与逆变器控制电源之间的串扰，此时应注意PLC与逆变器分开接地，避免两者之间使用共用接地线。

When connecting digital signals, note that:

(1) When the relay output PLC is connected to the inverter, it should be noted that poor contact often brings about the wrong operation of the inverter, so it should be noted that the connection is reliable in the actual wiring.

(2) When the transistor output PLC is connected to the inverter, attention should be paid to the limiting conditions such as the voltage level of the transistor itself and the size of the current within its range to ensure the reliability of the system.

(3) When designing the input signal circuit of the inverter, the inductive load such as relay should be avoided as far as possible, because the surge current generated by the opening and closing of the relay may cause the wrong operation of the inverter.

(4) When the switching signal output by the PLC enters the inverter, sometimes crosstalk between the external power supply and the inverter control power supply will occur, and attention should be paid to the separate grounding of the PLC and the inverter to avoid the use of a common grounding wire between the two.
