When the binary input terminal is connected to 24V, the input signal is active low:
• For a normal open switch, conducting to GND means the input signal can be
received .
• For a normal close switch, disconnecting with GND means the input signal can
be received.
2.1.2 Open Collector Output Signal
The output port of NK105 (E) control box with four axes belongs to open
controller output, with the maximum output current 50mA.
The wiring diagram of the output port connected to a solid-state relay is as follows:
2.1.3 Analog Output Signal
SAV, an output port for 0V ~ 10V controllable voltage, is connected to the input port
for analog voltage frequency of the inverter. Therefore, you can control the inverter
frequency by changing the controllable voltage, so as to control the spindle speed.
The schematic diagram is as follows:
