2.3.6 Spindle port
As Figure 2-2 showed,No.6 port is Spindle port. The interface definition is
VSO/GND/OT1/OT2 from left to right. Where VSO is the 0-10V analog output, OT1/OT2
digital drive signal output, spindle control output interface and spindle inverter connection
diagram figure 2-11. VSO/GND/OT1/OT2 are respectively connected with the inverter
AIN1/COM/X1/X2, where AIN1 is the input speed signal, COM converter X1 and X2 are the
