6.1 Brief
The input signal end of step-servo motor driver employs the light-coupled isolation technology.
For the step-by-step impulse signal, some isolate the side OC diode from cutoff to conduction
(e.g. the valid falling edge of pulse signal inputted from the diode minus end) and some do so
from conduction to cutoff (e.g. the valid rising edge of pulse signal inputted from the diode minus
end).
When it is indicated whether the pulse signal of motor driver is the valid rising edge or the valid
falling edge, it will be subject to the pulse signal inputted from the minus end of side OC diode.
Some input signals of motor driver are independent and some are internally of common anode,
so some have 4 external leading-out wires and some 3 wires (only the pulse and directional
signals are counted) as shown in Figure 6.1-1 and 6.1-2.
RDC644XG Controller has four groups of 3-wires motion driver interface, each interface has one
direction signal, one pulse signal, and one 5V positive output, the direction signal and the pulse
signal are all OC output.
RDC644XG controller must be common anode with the motor driver. The polarity of
the direction signal can be changed in the factory parameters, and the valid edge of
the pulse signal can also be changed.
