9 / 68 page 8 ■ Input circuit configuration • Shaded area indicates internal photo coupler ON . • EXT input signal EXT photo coupler ON enables a function by external F/H input signal. EX T photo coupler OFF enables the set ting of a number of micro steps by main unit’s rotary switch S.S. • F/ H input signal F/H photo coupler ON sets HALF step (2-division) operation. F/H photo coupler OFF sets FULL step (1-division) operation. • Refer to switching EXT and F/H input signal in the [FULL /HALF input signal, command pulse, and step angle select]. • When switching the step angle by EXT and F/H input signal, the phase origin LCD may not turn ON and the phase origin monitor output may not output when stop. Refer to the MON output in the [Output Interface]. ■ Output circuit configuration(BUSY、MON、AL) Output interface ■ Mon output • When the motor excitation phase is at the phase origin (power ON status), the photo coupler is turned ON , and the upper D.P of status LED turns on synchronously. • Output from MON is set to on at every 7.2 degrees of motor output shaft from phase origin. Approx. 10mA Input signal Command pulse 100μs MIN. 10μs MIN. ◎ Input circuit configuration( PD、EXT、F/H、EMG) ◎ Timing of command pulse, step angle selection, and FULL/HALF selection input signal Output signal MAX. 20mA MAX. 30V Driver CW pulse CCW pulse Mon output Phase origin position Phase origin position Motor shaft Switching to FULL step by external F/H FULL step HALF step Stop position at FULL step ◎ When changing the division setting by F/H input signal. • When changing the motor division setting by the external input signal and the rotary switch as shown in the example below, the motor cannot stop where MON output signal can be output. Take this into consideration when using the MON output signal. |
