TWO Dividing BCD Input, Bcd Div | Hitachi SJ-DG specification

CHAPTER 5 FUNCTION

5.1.4 TWO DIVIDING BCD INPUT

Setting of dip switch TYPE

It is possible to change setting data by twice input of data, higher data

and lower data. And it is possible to select frequency setting, torque limit

setting, acceleration and deceleration time setting, or position setting by

change of classification code (Refer to Figure 5.2 Table of classification

code.). Setting resolution can be selected by rotary switch CODE.

(Example of setting) In case of setting acceleration time to 60.0sec by 0.1sec resolution

D15 D14 D13 D12 D11 D10 D 9 D 8 D 7 D 6 D 5 D 4

D 3 D 2 D 1

D 0

Lower code setting frequency

Lower 8 bits setting data

(Setting of rotary switch CODE ---- 1, 4, 7, A)

(1)Converse value which 60 multiply 10 to binary value of BCD. And then input higher 2-figure data to D7 to D0 terminal, acceleration time setting higher code to D15 to D8 terminal.

60×10 = 600 0000011000000000 (Binary)

D15 D14 D13 D12 D11 D10 D 9 D 8 D 7 D 6 D 5 D 4 D 3 D 2 D 1 D 0

Acceleration time setting higher code

Higher 2-figure setting data

(2)When data input is definite, turn the strobe signal on.

(3)Turn the strobe signal off.

(4)Input remaining data, lower 8 bits to D7 to D0 terminal, and D15 to D8 terminal to lower code of setting frequency.

D15 D14 D13 D12 D11 D10 D 9 D 8 D 7 D 6 D 5 D 4 D 3 D 2 D 1 D 0

Acceleration time setting lower code

Lower 2-figure setting data

(5)When data input is definite, turn the strobe signal on.

(6)Turn strobe signal off.

Precaution Refer to 5.3 ”DATA INPUT TIMING” for signal input timing.
