11. e basic function of a motor driver is to provide the rated motor phase current to the motor windings in the shortest possible time The bilevel driver uses a high voltage to get a rapid rate of current rise in the motor windings in the least amount of time When reaching the preset trip current the driver turns off the high voltage and sustains the current from the low voltage supply Half Step Full Step Users have a choice of full step operation or half step operation Full step operation occurs by energizing two phases at a time rotating a typical motor 1 8 degrees per step Half step operation occurs by alter nately energizing one and then two phases at a time rotating the motor 0 9 degrees per step Full step operation is suggested for applications that specifically require that mode such as when retrofitting exist ing full step systems www nok eroup cn Clock Modes The BLD75 has two clock options Clock and Direction or Dual Clock operation Jumper JP2 is used to select the clock option Basically JP2 selects Terminal 5 as either the Direction input or the CCW input With the Clock and Direction option most common option clock pulses applied to the Clock input Ter minal 6 cause the motor to step The direction of the motor is determined by the logic level of the Direction input Terminal 5 Jumper JP2 must be in the 2 3 position for this mode see Figure 4 and Table 1 Physical direction also depends on the motor wiring
