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
(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)
(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.
(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.
