4 / 8 page Control of the motor The stepper motor can rotate in either direction according to the sequence of the input signals. It is possible to obtain a full step, a half step and quarter step operation. Full step operation Both windings of the stepper motor are energized all the time with the same current IMA = IMB. IN0 and IN1 remain fixed at whatever torque value is required. Calling A the condition with winding A energized in one direction and A in the other direction, the sequence for full step rotation is: AB ®AB®AB®AB etc. 4 Typical Performance Characteristics Source Saturation Voltage vs. Output Current (Conduction Period) Source Saturation Voltage vs. Output Current (Recirculation Period) 1 2 3 4 0.2 0.4 0.6 0.8 I (A) 0 1 2 3 4 0.2 0.4 0.6 0.8 I (A) 0 Comparator Threshold vs. Junction Temperature Sink Saturation Voltage vs. Output Current 1 2 3 4 0.2 0.4 0.6 0.8 I (A) 0 40 160 TJ (C) 0 20 40 60 80 100 60 80 100 120 140 20 The application diagram shows a typical application in which two CS3717A's control a two phase bipolar stepper motor. Programming The amplitude of the current flowing in the motor wind- ing is controlled by the logic inputs IN0 and IN1. The truth table (page 3) shows three current levels and an off state. A high level on the ÒDirectionÓ logic input sets the direction of that current from OUTA to OUTB; a low level from OUTB to OUTA. It is recommended that unused inputs are tied to VCC or (Gnd) as appropriate to avoid noise problems. The current levels can be varied continuously by changing VREF. Application Information |
