Flip Over
Selecting Between Full and Half Step Operation
The top switch in the bank of DIP switches selects between FULL and
HALF step operation.
Setting Phase Current
The drive uses a combination of DIP switch settings to set the current. There is al-
ways a base current of 0.4A. To increase this current slide the switch for each value
towards the label until they add up to your required value.
Suppose you want to set the driver for 2.2 amps per phase. You need the 0.4 A
base current plus another 1.6 and 0.2 A.
2.2 = 0.4 + 1.6 + 0.2
Slide the 1.6 and 0.2 A switches toward the labels as shown in the figure.
Connecting Logic
A schematic diagram of the input circuit is shown below.
You must supply 5 volts DC to activate the LEDs on
the input side of the optoisolators. The maximum
current draw is 15 mA.
Your controlling logic must be capable of sinking at
least 5 mA to control each drive input. Most CMOS
and open collector TTL devices are directly compat-
ible with this drive. Logic low, or 0, for a given input
occurs when that input is pulled to less than 0.8 volts
DC. In this state the LED is conducting current. Logic
high, or 1, occurs when the input is greater then 4 volts or open.
STEP
tells the driver when to move the motor one step.
DIRECTION
signals which way the motor should turn.
ENABLE
allows the user to turn off the current to the motor by setting this signal
to logic 0.
If you have no need to disable the amplifiers, you don’t need to connect
anything to the ENABLE input.

Connecting the Motor
STEP motors have 4, 6 or 8 leads, these are wired to 4 connections on the
drive in various combinations.
Motors will perform differently
according to the way it is con-
nected, to find out more about
the different ways of connecting
your motor, see the specs or
FAQs on our website.
Warning: When connecting the motor to the driver, be sure that the motor
power supply is off. Secure any unused motor leads so that they can’t
short to anything. Never disconnect the motor while the drive is powered
up.
Never connect motor leads to ground or to a power supply!

Using the Oscillator
Drives with an O suffix are equipped with internal
pulse generators that you can use to drive the mo-
tor. To set the drive to oscillator mode, simply find
the jumper located near the center of the printed
circuit board and move it to the SLEW setting. The
figure at the right shows the proper setting of the
jumper.
To change the slew speed, locate the trimpot labeled SPEED. By turning the brass-
screw you can raise or lower the speed. Turning the screw clockwise makes the
motor run faster.
The acceleration and deceleration rates can also be adjusted using the
trimpots labeled ACCEL and DECEL. Turning the screw clockwise makes
the motor accelerate and decelerate faster.
