Analog Output Signal
Command Pulse Signal
2.3.1 Switch Value Input Signal
The switch value input signal supports active high and active low:
Connecting to the COM port in NO mode means to receive signal.
Disconnecting with the COM port in NC mode means to receive signal.
The figure is as follows:
The input port supports active high and active low:
When the common terminal board S of the Lambda controller is connected to the
COM port, inputs are active in high voltage.
When the common terminal board S of the Lambda controller is connected to the
+24V port, inputs are active in low voltage.
2.3.2 Relay Output Signal
The Lambda controller outputs relay signals.
The load capacity of relay output contact points is AC 7A/250V or DC 7A/30V. If high
power load is needed, a contactor should be connected as follows:
The figure is as follows:
2.3.3 Relay Output Signal
The AVC port, externally connected to the inverter's analog voltage frequency command
input port, can output controllable voltage from 0V to 10V. By changing the voltage, it
controls the inverter frequency and in turn the spindle speed.
