1. Users can set the time it takes for the input terminals X0~X7 to respond by setting
D1020. The value in D1020 must be in the range of 0 to 20. (Unit: ms)
2. If the DVP-20PM series motion controller is turned form OFF to ON, the value in S
D1020 will automatically become 10.

D1020 is set. The value in D1020 is 10.
3. If the program below is executed, the time is takes for the input terminals X0~X7
to respond will be 0 milliseconds. Owing to the fact that the input terminals are
connected to resistor-capacitor circuits in series, the shortest time it takes for the
input terminals to respond is 50 microseconds.

4. If high-spedd counters and interrupts are used in a program, the value in D1020
does not have any effect.

The communication ports with which a DVP-20PM series motion controller is equipped
are COM1 (RS-232 port) and COM2 (RS-485 port). They support Modbus ASCII/RTU.
The maximum speed available is 115,200 bps. COM3 (RS-232/RS-485
communication card) supports Modbus ASCII. The maximum speed available is
38,400 bps. COM1, COM2, and COM3 can be used simultaneously.
COM1 COM1 can only be used as a slave station. It supports ASCII/RTU, and
the adjustment of a communication speed. The maximum speed available
is 115,200 bps. It supports the modification of the number of data bits.
COM2 COM2 can be used as a master station or a slave station. It supports
ASCII/RTU, and the adjustment of a communication speed. The maximum
speed available is 115,200 bps. It supports the modification of the number
of data bits.
COM3 COM3 can only be used as a slave station. It supports the ASCII
communication format 7, E, 1 (7 data bits, even parity bit, 1 stop bit), and
the adjustment of a communication speed. The maximum speed available
is 38,400 bps. COM2 and COM3 can not be used as slave stations
simultaneously.
