1. Introduction
The EM882S is a new digital stepper drive based on Leadshine’s widely implemented DM stepper drives (10+ millions
of units in field). While retaining features of simple design, easy setup, high precision and reliability, Leadshine has
also upgraded it by adopting the latest stepper control technology and added additional advanced features for better
torque (10-25%), quicker response time, control command smoothing, motor selector, etc.
The EM882S is able to power 2 phase (1.8°) and 4 phase (0.9°) stepper motors smoothly with very low motor heating
& noise. It can take 20-80VDC supply voltage and output 0.5 to 8.2A current. All the micro step, output current
configurations and motor model selection can be easily done via built in DIP switches. Therefore, the EM882S is an
ideal choice for many applications requiring simple step & direction or CW/CCW control of NEMA 23, 24 and 34
stepper motors.

5. Stepper Motor Connections
EM882S can drive 2-phase and 4-phase bipolar hybrid stepper motors with 4, 6, or 8 leads, Motion Control Products
also offers easy-to-use and good-performance motors with 4-leads, ideal for running with the EM882S:
https://www.motioncontrolproducts.com/electric-motors/stepper-motors/hybrid-stepper-motors/
5.1 4-lead Motor Connection (recommended)
4-lead motor is easy to use with excellent performance. Refer to figure 8 for how to connect a 4-lead stepper motor.
P4
Figure 7 4-lead Motor Connection

EM882S Digital Stepper Drive User Manual
Motion Control Products Ltd. Tel.: [phone] www.motioncontrolproducts.com Page | 6
5.2 6-lead Motor Connection
EM882S can power 6-lead stepper motors through half coil connection (half chopper) or full coil (full copper)
connection. The half coil connection only uses one half of the motor’s winding and is usually selected in applications
requiring high speed but lower torque. The full coil connection uses the full coil winding and is usually selected in
high-torque required applications. Refer to figure 8 and 9 for those two connections.
P4
P4
Figure 8 6-lead motor half coil connection Figure 9 6-lead motor full coil connection
5.3 8-lead Motor Connection
EM882S can power 8-lead in series or parallel connection in series or parallel.
Series connected 8-lead stepper motors are typically implemented in applications which higher torque at lower speed
movement is required. Because a stepper motors under series connection has the most inductance, the performance
will start to degrade when the motor runs at higher speed. For this connection, it is suggested to set an EM882S’s
output RMS current to no more than 70% of the stepper motor’s phase current to prevent overheating. See the figure
10 for how to connect an 8-lead stepper motor for series connection.
Parallel connected 8-lead stepper motors are typically implemented in applications which higher torque at high speed
movement is required. Compared with series connection, a parallel connected stepper motor has lower inductance
and therefore have better torque performance at higher speed movement. Although setting the drive output current
to 1.4 times of driven motor phase current will get the most torque, it is suggested to set an EM882S’s output current
(peak of sinusoidal) to no more than 1.2 times the stepper motor’s phase current to prevent overheating. Refer to the
figure 11 for how to connect an 8-lead stepper motor for parallel connection.

6. Power Supply Selection
EM882S is designed to power stepper motors (frame sizes NEMA 23 to 34) made by Leadshine or other motor
manufacturers. To get optimal performances, it is important to select proper power supply type, voltage, and supply
output current. In general power supply voltage determines the high speed performance of a stepper motor, while
drive output current determines the driven motor torque output. Higher supply voltage can increases motor speed
torque performance, but at the same time result in more noise and motor heating. For low motor speed applications,

EM882S Digital Stepper Drive User Manual
Motion Control Products Ltd. Tel.: [phone] www.motioncontrolproducts.com Page | 7
it is suggested to use lower supply voltage power supplies.
6.1 Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to power an EM882S. Theoretically unregulated power
supplies are preferred due to their ability to withstand back EMF current surge and faster response for current change.
If you prefer to use a regulated power supply instead, it is suggested to choose one specially designed for stepper or
servo controls.In the case when only general purpose switching power supplies are available, choose one with
“OVERSIZED” current output rating (for example, using a 4A power supply for 3A stepper motor) to avoid 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 phase current). The reason is that the drive only draws current from an
unregulated power supply during the ON duration of the PWM cycle, but not during the OFF duration.
6.2 Power Supply Sharing
Multiple EM882S drives can share the same power supply, if that power supply has enough capacity. To avoid cross
interference, connect each EM882S DIRECTLY to that shared power supply separately instead of connecting those
power connectors of drives in daisy-chain connection.
6.3 Selecting Supply Voltage
EM882S’s operating voltage is 20-80 VDC. Because of voltage increasing from potential power line voltage fluctuation
and back EMF voltage generated during motor deceleration, it is suggested to use a 24-72 VDC power supply.
7. DIP Switch Configurations
The EM882S has one 8-bit DIP switch and one 16-bit rotation switch selector. “Default”means that parameters can be
modified by Leadshine ProTuner software.
The DIP switch S1 in Figure 2 and used to configure settings of micro step resolution, output current, and motor
standstill current as shown below, the factory setting of SW1-SW8 is ON, ON, ON, OFF, ON, ON, ON, ON.
SW1
SW2
SW3
SW4
SW5
SW6
SW7
SW8
The rotation Switch S2 is located on the top (rotation switch selector 2 in figure 2) for motor selection.
7.1 Output Current Configuration (SW1-3)
The EM882S has 8 output current settings which can be configured through DIP switch SW1, SW2 and SW3.
For a given stepper motor, as normal setting the output current to 1.4 times of motor phase current, will make it
output larger torque, but at the same time cause more heating for both the motor and drive. Therefore, it is
suggested to set a output current (peak of sinusoidal) to no more than 1.2 times the stepper motor’s (for 4-lead
motor) phase current to prevent overheating .
The SW1, SW2 and SW3 are used to set the dynamic current. Select a setting closest to your motor’s required current.
When they are set to ON, ON, ON, the output current can be set by Leadshine ProTuner.

7.2 Idle Current Configuration (SW4)
The SW4 of an EM882S is used to set output current percentage when motor is standstill. Idle current percentage will
be set to 50% at OFF position, and 100% at ON position. When the driven stepper motor is idle (no movement) for 0.4
second, the output current of EM882S will be automatically reduced to the configured percentage.
7.3 Micro Step Configuration(SW5-8)
Each EM882S has 8 micro step settings which can be configured through DIP switch SW5, SW6, SW7 and SW8. See the
following table for detail. When they are set to ON, ON, ON,ON, the microstep can be set via Leadshine ProTuner.

7.4 Auto-tuning and Motor Model Selection (Rotary Switch)
Auto-tuning means that the current loop parameters are automatically configured when the EM882S is powered on.
When the rotary switch is set to “0”, or “8”- “F”, you can turn off auto-tuning and modify current loop parameters
through ProTuner
Motor Model Selection means that the current loop parameters and resonant point damping parameters are
automatically configured when EM882S is powered on.
Every time change the rotary switch, you need to restart the power supply to activate the setting.
7.5 Smoothing Filter Time Configuration (ProTuner)
EM882S 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. The Filter Time value must be set to the same for each EM882S in multi-axis applications
7.6 Activated Pulse Edge Configuration (ProTuner)
The factory setting is activated at voltage rising edge, make sure this setting will match the pulse generator (controller,
PLC, etc.). When the stepper motors loss step, first this parameter for a test.
7.7 Control Mode Configuration (ProTuner)
The factory setting is single pulse (step & direction, or pulse & direction) control. Please modify this parameter when
you need the double pulse (CW/CCW) control mode.
8. Wiring Notes
⚫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 only one power supply serves multiple EM882S drives, separately connecting the drives to the power supply is
recommended instead of daisy-chaining.
⚫It is prohibited to pull and plug connector P3&P4 while the drive is powered ON, because there is high current

12. 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.
