2.3 Drive installation requirements
Please install the drive vertically or horizontally, with its front facing forward, top facing upward to facilitate
cooling.
During assembly, avoid drillings and other foreign matters falling inside the drive.
During assembly, please use M3 screw to fix.
When there is vibration source (such as a driller) close to the installation position, please use a vibrating
absorber or a vibration resistant rubber gasket.
When multiple drives are installed in the control cabinet, please pay attention to reserve enough space for
sufficient heat dissipation. If necessary, you can configure cooling fans to ensure good heat dissipation

3.2 Power supply input
The power supply of the drive can be both AC power and DC power, and the input voltage range is AC
20~80V ,DC 24~100V. The AC power supply voltage should not exceed 80VAC. Do not directly connect to
220VAC mains! ! !
Input power polarity should not be reversed!!!
The drive’s work mode is constant current control. The drive output the voltage to motor by changing the input
power into PWM chopping wave when it is working. In this case, the input power will affect the performance of
drive.
Power selection reference:
Voltage:
The stepper motor has the characteristic of torque decreasing as the motor speed increases, and the voltage of
the input power supply will affect the declining amplitude of the motor torque at high speed. Increasing the
voltage of the input power supply appropriately can increase the output torque of the motor at high speed.
And use low voltage when it is low speed required, can lower motor’s heating appropriately.
Current:
The work of the drive is to convert the input power supply with high voltage and low current to the low voltage
and high current at both terminals of the motor winding.In this case, the current of power supply will be lower

3DM580S USER MANUAL

than the motor’s.
The effects of regeneration voltage:
When the stepper motor is working, it also keeps the characteristics of the generator. At deceleration, the
kinetic energy accumulated by the load is converted into electric energy, which will be superimposed on the
drive circuit and the input power. In application, attention should be paid to the setting of acceleration and
deceleration time to prevent the protection of the drive or power supply.
When the drive is powered off, similarly, the drive LED indicator will be on if the load is increased to allow the
motor to move
3.3 Motor connection
The matching motor of the 3DM580S-IO drive is the low resistance and low inductance hybrid stepper motor.
The common 3-phase stepper motor’s lead number are 3 and 6.
3.4 Control signal connection
3.4.1 IN Port: connection for pulse command
The signal interface of standard DM series drive is switch.
The upper controller can be the pulse signal generating device, such as PLC, MCU, control card and controller.
The pulse level that R86 drive can be used: 3.3V-24V (no need to connect resistor)

3. 4.2 ENA port: enable/disable
When the default optocoupler is off, the drive outputs the current to the motor. When the internal optocoupler
is on, the drive will cut off the current of each phase of the motor so that the motor is in a free state, and the
stepper pulse can not be responded.
When the motor is in the wrong state, ，the drive can be restarted by ENA input。The existing fault should be
cleared at first. Then input a trailing edge signal to ENA terminal. After that, the drive can be excitation again
and running.
The level logic of the enable signal can be set to the opposite. The logic is opposite with above mentioned.

DIP SW1, SW2, SW3, SW4 are used to set current which is output from drive to motor.
Generally, the current setting is the motor rated current. If your system has high request to the heating, please
decrease the current properly to lower the motor’s heating, but at the same time, the output torque will be
lower. If you don’t need the motor running continuous, you can increase the current to higher the torque. But
be minded that the current can not be 1.5times over than the rated current.

DIP SW6, SW7, SW8 are used to set the speed when the motor is triggered. Built-in S-type acceleration and
deceleration.
When the switch is closed, the motor accelerates to the set speed.
When the switch is off, the motor decelerates and stops.
4.2 Motor direction selection
DIP SW5 is used to set the running direction of the motor under the initial pulse.
The “off”means that the motor direction is counterclockwise when inputting the initial pulse;
The “on”means that the motor direction is clockwise when inputting the initial pulse.

※The initial pulse is the testing pulse used when developing the drive software; Please refer to the actual
running direction of the motor.
4.3 Pulse filtering function selection
DIP SW6 is used to set the pulse filtering function of drive.
The “off”means the pulse filtering function is off;
The “on”means the pulse filtering function is on.
※The pulse filtering function is the filtering action by the drive upon the input commands. When the filtering
function is on, the drive will smoothen the input pulse command to make the acceleration and deceleration of
motor softer, but this will also cause certain delay of the pulse command.
Filtering time setting: The default time of filtering function is 6.4ms, and the software can change the time
below the 25.6ms.
4.4 Pulse mode selection
DIP SW7 is used to set the pulse command mode of drives.
The “off”means pulse + direction (single pulse) mode; the “on”means double pulse mode.
※When you need to set the drive pulse mode to A/B orthogonal pulse mode, set the pulse mode check
function to A/B orthogonal pulse mode in the testing software and turn on SW7.
4.5 Open/closed loop selection
DIP SW8 is used to set the drive control mode.
The “off”means the closed loop control mode;
The “on”means the open loop control mode.
※
※The above parameters are set for the DIP switches;For other parameters, please refer to Appendix A:
