2.2 Lambda 4S/5S Series Controller
The normal working range of Lambda 4S/5S series controller is 17V~30V, and the rated voltage is
24V. When the voltage difference between power voltage and the Common S is over 8V, the input
connection becomes effective. The inputs of Lambda 4S/5S series controller can be active high/low, so
can the extended terminal board. When Common S is connected to COM, inputs are active high;
when to +24V, active low.
The wirings below are for the general software for the time being, provided for reference only. Please refer to the
specific software for IO definitions and IO wiring, because IO definitions and IO wiring change with software IO
definitions.
2.2.1 Engraving and Milling
See this section for the wiring diagrams of controller for three to five axes engraving and milling
machines.
For three and four axes engraving and milling machines, Lambda 4S controller is used. When IOs
are not enough, you can choose extended terminal board EX27A.
For five axes engraving and milling machines, Lambda 5S controller is used. When IOs are not
enough, you can choose extended terminal board EX31A.
