Notes:
(1) ENA signal is no-connected as default;
(2) Control signal amplitude is 24 V as default. If it is 12 V, please set the S2 (Figure 2) selector switch to 5 V first, then connect 1KΩ
resistor; If it is 5V, please set the S2 to 5V.
4.2 Fault and Brake Outputs Connection
Fault Output
When over voltage or over current protection happens, 3DM883 red status LED light will blink and the impedance state between
ALM+ and ALM- will change (from low to high or high to low depending on configuration) and can thus be detected. Fault
output connection is optional, and it can be connected either in sinking or sourcing.

Brake Control
This signal can be used for automatic brake control while system power failure.
When use a 24V electromagnetic relay, it is recommended to connect a diode (such as IN4007) in parallel, the polarity should not
be reversed. The specific connection is as follows figure7A . When use a solid-state relay (SSR), its advantages are fast response,
no need to add diodes, no noise; specification such as “Non-contact, DC control DC, current limit protection 0.6-10A”.The
specific connection is as follows figure7B

4.3 Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram:

Figure 8 Sequence chart of control signals
Remark:
(1) t1: ENA must be ahead of DIR by at least 500ms. Usually, ENA+ and ENA- are NC (no connected).
(2) t2: DIR must be ahead of PUL effective edge by 5us to ensure correct direction.
(3) t3: Pulse width not less than 1us, these widths are based on a 50% duty cycle. If it is greater or less than 50%, the
width time is required to be wider.
4.4 Typical Connection
In order to improve anti-interference performance of the Drive, it is recommended to use twisted pair shield cable.
To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires should not be tied up together. It
is better to separate them by at least 10 cm, otherwise the disturbing signals generated by motor will easily disturb pulse
direction signals, causing motor position error, system instability and other failures.
If a power supply serves several Drives, separately connecting the Drives is recommended instead of daisy-chaining.
It is prohibited to pull and plug connector P3 while the drive is powered ON, because there is high current flowing through
motor coils (even when motor is at standstill). Pulling or plugging connector P3 with power on will cause extremely high
back-EMF voltage surge, which may damage the Drive.
It is strictly prohibited to add tin to the wire head to access the terminal, otherwise the contact resistance may become large
and overheating damage to the terminal.
The wire head should not be exposed outside the terminal to prevent accidental short circuit and damage to the drive.
5. DIP Switch Configurations
The 3DM883 has one 10-bit DIP switch and one 1-bit selector. The first 10-bit is used to configure settings of micro step
resolution, output current, motor standstill current, pulse type and smoothing time as shown below.

SW3
SW4
SW5
SW6
SW7
SW8

SW10
The second 1-bit selector is located on the top (S2 in figure 2), used to configure the voltage of control signals. For the safety of
optically coupled, the factory setting is 24V, which no need to connect 2K resistors like the old drives, making it easier to use.
When the voltage of the control signal is 5V, the S2 must be set to 5V, otherwise, the motor won't work.

5.2 Output Current Configurations
For a given motor, higher drive current will make the motor to output more torque, but at the same time causes more heating in
the motor and drive. Therefore, output current is generally set to be such that the motor will not overheat for long time operation.
Since parallel and serial connections of motor coils will significantly change resulting inductance and resistance, it is therefore
important to set drive output current depending on motor phase current, motor leads and connection methods. Phase current
rating supplied by motor manufacturer is important in selecting drive current, however the selection also depends on leads and
connections.
The first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor’s
required current.

Notes: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under
high speed condition. Default means can be set by Leadshine ProTuner
5.2.2 Idle Current Configuration
SW4 is used to set motor idle current percentage. At OFF position it means the standstill current is set to be 50% of the selected
output current. At ON position it means standstill current is set to be 90%.
The current automatically reduced to 50% of the selected dynamic current 0.4 second after the last pulse.
5.3 Control Mode Configurations
DIP switch SW9 is used to configure the control mode. Factory setting is single pulse (step & direction, or pulse & direction)
control. Setting to ON to change the control model to double pulse (CW/CCW) control type.
5.4 Smoothing Time Configuration
3DM883 has an advanced feature called control command smoothing to make the input pulse from pulse generator (controller,
PLC, etc.) S-curve acceleration, to improve motion smoothness and high-speed start frequency in many circumstances. This is
achieved through adding filtering time which is configured SW10. Setting to ON to activate the feature with 12ms acceleration
time.
5.5 Automatic Motor Matching & Self Configuration
When powered on a 3DM883 will automatically configure itself with the best settings to match the driven stepper motor for
optimal performance. No action is needed.
6. Power Supply Selection
The 3DM883 can power small and medium size 3-phase stepper motors (frame size from NEMA23 to 34) from Leadshine or
other motor manufacturers. To get good system performance, it is important to select proper supply voltage and output current.
Generally speaking, supply voltage determines the high speed performance of the motor, while output current determines the
output torque of the driven motor (particularly at lower speed). Higher supply voltage will allow higher motor speed to be
achieved, at the price of more noise and heating. If the motion speed requirement is low, it’s better to use lower supply voltage to
decrease noise, heating and improve reliability.
6.1 Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the drive. However, unregulated power supplies are
preferred due to their ability to withstand current surge and fast response for current change. If you prefer to a regulated power
supply, it is suggested to choose such a power supply specially designed for stepper/servo controls such as Leadshine LSP series .
Or, in the case when only normal switching power supplies are available, it is important to use “OVERSIZE” high current output
rating power supplies (for example, using a 4A power supply for 3A stepper motor) to avoid problems such as current clamp. On
the other hand, if unregulated supply is used, one may use a power supply of lower current rating than that of motor (typically
50%-70% of motor current). The reason is that the drive draws current from the power supply capacitor of the unregulated supply
www.oyostepper.com

3DM883 3-Phase Digital Stepper Drive User Manual
Email: [email protected] TEL: [phone]
10
only during the ON duration of the PWM cycle, but not during the OFF duration. Therefore, the average current withdrawn from
power supply is considerably less than motor current. For example, two 3A motors can be well supplied by one power supply of
4A rating.
6.2 Power Supply Sharing
Multiple 3DM883 drives can share one power supply to save space and reduce cost, if that power supply has enough power
capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply separately. To avoid cross
interference, DO NOT daisy-chain connect the power supply input pins of the Drivers. Instead connect them to power supply
separately.
6.3 Selecting Supply Voltage
The 3DM883 is designed to operate under 74VDC voltage input. When selecting a power supply, besides voltage from the power
supply power line voltage fluctuation and back EMF voltage generated during motor deceleration needs also to be taken into
account. Ideally it is suggested to use a power supply with the output of 20-48VDC, leaving room for power line voltage
fluctuation and back-EMF.
Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. However, higher
voltage may cause bigger motor vibration at lower speed, and it may also cause over-voltage protection or even drive damage.
Therefore, it is suggested to choose only sufficiently high supply voltage for intended applications.
7. Motor Selection
The 3DM883 can be used to drive 3- or 6-wire three-phase hybrid stepper motors with a step angle of 1.2 degrees. The choice of
motor is mainly determined by the motor torque and current rating. The torque size is mainly determined by the size of the motor.
The larger the size of the motor, the higher the torque of the motor; while the current size is mainly related to the inductance, the
motor with small inductance has good performance in high speed performance, but the current is higher.

8. Troubleshooting
In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in
nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to
disconnect the individual components that make up your system and verify that they operate independently. It is important to
document each step in the troubleshooting process. You may need this documentation to refer back to at a later date, and these
details will greatly assist our Technical Support staff in determining the problem should you need assistance.
Many of the problems that affect motion control systems can be traced to electrical noise, controller software errors, or mistake
in wiring.
