Mounting dimension(unit:mm）
You can mount the drive on the wide or the narrow side of the chassis using #2 screws.If possible,the drive should be
securely fastened to a smooth,flat metal surface that will help conduct heat away from the chassis. If this is not possible,then
force airflow from a fan may be required to prevent the drive from overheating. See below installation image:
Note:
•Never use the drive in a space where there is no air flow or where other devices cause the surrounding air to be more
than 50 ℃ .
•Never use the drive in a space where the temperature is under -10 ℃
•Never put the drive where it can get wet or where metal or other electrically conductive particles can get on the
circuitry.
•Always provide air flow around the drive.When mounting multiple drives near each other,maintain at least one half
inch of space between drives.

Connecting the Power Supply
If you need information about choosing a power supply, please read the section Choosing a Power Supply
•Connect the power supply “+” terminal to the connector terminal labeled “AC1 or AC2”
•Connect power supply “-” to the connector terminal labeled “AC1 or AC2”
•The screw in the center of drive chassis should be connected to earth ground
•Use 18 or 20 gauge wire
Power Supply and Ground Connection
Transformer Selection
When choosing a transformer, there are many things to consider.You must decide what size of (in terms of voltage
and current) is needed for your application.
ECON Technology recommend HB500-60 transformer for drive:DH860
Voltage
Your motor can provide more torque at higher speeds if a higher power supply voltage is used. Please consult the
speed-torque curves later in this manual for guidance.
If you choose an unregulated power supply, make sure the no load voltage of the supply does not exceed the drive’s
maximum input voltage specification.
Current
The maximum supply current you could ever need is two times the motor current. However, you will generally need a
lot less than that, depending on the motor type, voltage, speed and load conditions. The more the power supply voltage
exceeds the motor voltage, the less current you’ll need from the power supply. A motor running from a 48 volt supply

can be expected to draw only half the supply current that it would with a 24 volt supply.
We recommend the following selection procedure:
1. If you plan to use only a few drives, get a power supply with at least twice “per phase” current rating of the step
motor. Example: for a motor that’s rated for 2 A/phase use a 4 A power supply..
2. If you are designing for mass production and must minimize cost, get one power supply with more than twice the
rated current of the motor. Install the motor in the application and monitor the current coming out of the power supply
and into the drive at various motor loads. This will tell you how much current you really need so you can design in a
lower cost power supply.
Motor Connecting
Never connect or disconnect the motor while the power is on.
Four Lead Motor
These motors can only be connected one way. Please follow the sketch below.

Configuring the Drive
Step 1: Selecting a Motor
The DH542 drive is optimized for use with carefully selected motors. To select a motor, simply move the rotary
switch to the letter or number that corresponds to the motor of your choice. You can do this while power is on, but it is
safer to select the motor before applying power to the drive so that you do not risk applying too much current to your
motor.
If your motor is not on the list, please set the switch to a selection whose rotor inertia, holding torque and current are
within 10% of your motor. Custom configurations can be added for qualifying applications.

Step 2: Setting the Current
The maximum current for the motor you have selected is set automatically when you set the rotary switch. But you
may want to reduce the current to save power or lower motor temperature. This is important if the motor is not
mounted to a surface that will help it dissipate heat or if the ambient temperature is expected to be high.
Step motors produce torque in direct proportion to current, but the amount of heat generated is roughly proportional to
the square of the current. If you operate the motor at 90% of rated current, you’ll get 90% of the rated torque. But the
motor will produce approximately 81% as much heat. At 70% current, the torque is reduced to 70% and the heating to
about 50%.
Three of the small switches on the front of the DH860 drive are used to set the percent of rated current that will be
applied to the motor: SW1,SW2 and SW3. Please set them according to the illustration below

Step 3:Setting Idle Current
Motor heating and power consumption can also be reduced by lowering the motor current when it is not moving. One
small switch on the front of drive can set the idle current,SW4 is ON,then the current is 100%,when SW4 is OFF,the
current is 50%. The 50% idle current setting will lower the holding torque to 50%, which is enough to prevent the load
from moving in most applications. This reduces motor heating by 75%. In some applications, such as those supporting
a vertical load, it is necessary to provide a high holding torque. In such cases, the idle current can be set to 90% as
shown below.
