Issues to Pay Attention to in Digital Signal Connection
The input signals of the frequency converter include digital input signals (switch type command signals) that operate on operating states such as running/stopping, forward/reverse, and jogging. These signals often come from the digital output signals of the PLC. PLC usually uses its internal relay contacts (relay output type PLC) or components with switching characteristics (transistor output type PLC) to connect to the frequency converter to obtain operating status instructions, as shown in Figure 1 and Figure 2. When connecting digital signals, attention should be paid to:
(1) When using a relay output type PLC to connect to a frequency converter, it should be noted that poor contact often leads to incorrect operation of the frequency converter. Therefore, in actual wiring, it is important to pay attention to reliable connection.
(2) When using a transistor output type PLC to connect to a frequency converter, attention should be paid to limiting conditions such as the voltage and current of the transistor itself within its range to ensure the reliability of the system.
(3) When designing the input signal circuit of the frequency converter, it should be avoided to use inductive loads such as relays as much as possible, as the surge current generated by relay opening and closing may cause the frequency converter to malfunction.
(4) When the switch signal output by the PLC enters the frequency converter, there may be crosstalk between the external power supply and the frequency converter control power supply. It is important to separate the grounding of the PLC and frequency converter to avoid using a common grounding wire.
