2. Wiring differential input terminals
The direct-current signals ranging in voltage from 5 V to 24 V can pass through the high-speed input
terminals A0~A1 and B0~B1 on a DVP-20PM series motion controller. The frequency of input signals
can be up to 200 kHz. These high-speed input terminals are connected to a differential (two-wire) line
driver.

If the frequency of input signals is less than 50 kHz and there is not much noise, these high-speed input
terminals can be connected to the direct-current power input whose voltage is in the range of 5 V to 24
V, as shown below.
