ENABLE allows the user to turn off the current to the motor by setting this signal to logic 0.DIRECTION signals which way the motor should turn.STEP tells the driver when to move the motor one step.Logic high, or 1, occurs when the input is greater then 4 volts or open. In this state the LED is conducting current. Logic low, or 0, for a given input occurs when that input is pulled to less than 0.8 volts DC. Most CMOS and open collector TTL devices are directly compatible with this drive. Your controlling logic must be capable of sinking at least 5 mA to control each drive input. You must supply 5 volts DC to activate the LEDs on the input side of the opt isolators. Slide the 1.6 and 0.2 A switches toward the labels as shown in the figure.Ī schematic diagram of the input circuit is shown below. You need the 0.4 A base current plus another 1.6 and 0.2 A. Suppose you want to set the driver for 2.2 amps per phase. To increase this current slide the switch for each value towards the label until they add up to your required value. The drive uses a combination of DIP switch settings to set the current. The top switch in the bank of DIP switches selects between FULL and HALF step operation. Never connect motor leads to ground or to a power supply! Selecting Between Full and Half Step Operation Never disconnect the motor while the drive is powered up. Secure any unused motor leads so that they can’t short to anything. Warning: When connecting the motor to the driver, be sure that the motor power supply is off. Motors will perform differently according to the way it is connected, to find out more about the different ways of connecting your motor, see the specs or FAQs on our website. STEP motors have 4, 6 or 8 leads, these are wired to 4 connections on the drive in various combinations.
