Connecting the Analog Output
The analog output connection is optional.
The MX4660 4-Axis stepper drive also comes with an opto-isolated
analog output (Figure 3) to allow control of an external analog device, such as a VFD for spindle control. Supply
voltage for the analog device is 5-15 VDC, and the output voltage signal is 0 to (Analog Supply Voltage minus 1.1
VDC).
On Figure 18, it shows how to connect a VFD to the opto-isolated analog output. Connect the VFD 10 VDC power
wire to “+10 VDC” pin, “Input” wire to “0-10V”, and GND wire to “GND”. Refer to figure 16 for more information
about their interface circuit.
Figure 18 Connecting a VFD to the MX4660
Figure 19 shows the relationship of the spindle speed output in Mach3 and analog output of the MX4660.
Testing conditions:
(1)
Used MACH3, settings: PWMBase Freq. = 10, Minimum PWM = 0%,
(2)
Used “+12Vdc Out”, the 12VDC auxiliary power output on the MX4660 as the power input for “+10Vdc in”
of the VFD (The measured value of the “+12VDC auxiliary power output of the MX4660” was
：
11.98VDC.).
(3)
Device for measuring voltage was Agilent digital oscilloscope DSO-X 3014A. (The raw data of the testing
results is available on request.)
