Clockwise direction (as seen from the outputshaft)“H” .... Counterclockwise direction (as seen from theoutput shaft)Note:Do not change the rotation direction within7μsec. before the first pulse of the MOTCLKbecomes ON and after the last pulse becomesOFF.Cut off the drive out-putMOTEN InputExcitation drive is turned ON/OFF.“H” .... Normal operation (Excited)“L”..... Excitation drive is forcibly shut off (Not excited)Voltage to set valuefor the motor currentMOTREF InputMotor wire current value is set in the range of 0 to 1.7(A)/phase by applying the analog voltage 0 to 5 (V).Set the excitationmode (1) to (3)MOTMD 1 to 3 InputSet the excitation mode.Note:Do not change the setting within 7μsec. afterthe first pulse of the MOTCLK becomes ON andthe last pulse becomes OFF.Reset MOTRST InputReset for the whole systemInternal circuit of the driver is initialized by setting themotor to “L” level (pulse interval: 10μsec. or more).The motor drive circuit is automatically reset when thepower is turned ON.05/11
