The ES (easy servo) series easy servos offer an alternative for applications requiring high performance
and high reliability when the traditional servo was the only choice, while it remains cost-effective.
The system includes an easy servo motor combined with a fully digital, high performance easy servo
drive. The internal encoder is used to close the position, velocity and current loops in real time, just
like servo systems. It combines the best of servo and stepper motor technologies, and delivers unique
many capabilities and enhancements over both, while at a fraction of the cost of a servo system.
Easy Servo Drive
Easy Servo Moto
Getting Start
To get start you need one easy servo drive, one easy servo motor (stepper motor with encoder) and
an AC / DC power supply to set up a minimum easy servo system. A motion controller - like indexer,
pulse generator or PLC is required too when you need to rotate the motor. If you have a PC with one
serial port or one PC with USB-RS232 converter, you can also rotate the motor via PC software,
ProTuner. However it is recommended to verify all function of an easy servo with a motion controller.

Connecting Encoder
As the easy servo drive works in close-loop mode, it needs to know the actual motor position. The
encoder mounted on the motor offers such information. Please note that the easy servo drive can
not work without encoder feedback.
ES-D508 and ES-M3 series motors
The encoder extension cable is required to connect the motor and ES-D508. The drive will not work
properly if you connect the motor’s encoder cable to the ES-D508 directly.

Connecting PC
There is a built-in RS232 port in each easy servo drive for communication and configuration. Connect
this port to the PC’s serial port. Then you can rotate the motor in the setup software. This setup
software - ProTuner, is designed to configure the easy servo drive. You can define the control mode,
microstep resolution, current rate, active level of inputs/outputs in ProTuner.
The ProTuner can be downloaded from our website: http://www.leadshine.com or you may also get it
from our CD. It is recommended to get it from the website because software from the website is
always the latest. Install it in your PC and make it ready for use later.

Connect ES-D808 / ES-D1008 to PC
A RS232 cable is needed for the communication between the drives and the ProTuner. It will be
shipped with the kit if you include it in the order. It is also possible to make this cable by yourself. One
end of this cable is a RJ-11 header and the other end of cable is a 9 pin D-Sub female connector. If
your PC does not have a serial port, a USB-to-232 converter is required.
Note: The power should be turned off when you perform any connections!
When you open ProTuner, a “Connect to drive” window appears. The “Baud Rate” and “Device
Address” are fixed. You only need to select the “Com Port” according to the actual serial port or the
mapping port of a USB-232 converter. Check the Device Manager for the mapping port number of
the USB-232 converter.

Wiring Notes
l In order to improve anti-interference performance of the system, it is recommended to use
twisted pair shield cable.
l 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 or other failures.
l If a power supply serves several drives, separately connecting the drives is recommended instead
of daisy-chaining.
l It is prohibited to pull and plug power connector while the drive is powered ON, because there is
high current flowing through motor coils (even when motor is at standstill). Pulling or plugging
power connector with power on will cause extremely high back-EMF voltage surge, which may
damage the drive.

Configuration
When the default settings of the easy servo drive are not suitable for your application, it is necessary
to configure the drive via the DIP switch or ProTuner (the setup software). Otherwise you may
encounter problems like high motor heating, big motor noise or even motor stall due to weak torque.
For a quick start of the easy servo drive, there are not much parameters need to be configured. The
following table gives the most significant parameters of the easy servo drive.
Most Significant Parameters of the easy servo drive
Adjustable
Holding Current (%) Default 40%, Software Adjustable Default 50%, Software Adjustable
Close-loop Current (%) Default 100% , Software Adjustable Default 100%, Software Adjustable
Current Loop Kp *Auto Tuning at Power-up *Auto Tuning at Power-up
Current Loop Ki *Auto Tuning at Power-up *Auto Tuning at Power-up
*Auto Tuning at Power-up: It is possible to disable this feature in the setup software in order to tune
the current loop Kp and current loop Ki manually if the auto tuning result is not good enough. This
happens when the motor’s inductance or resistance is too high or too low.
The holding current affects the holding torque when the motor is stop. The close-loop current affects
the dynamic torque. Increase them if the torque is not enough.
Recommended Holding / Close-loop Current Percentage
There are possible two methods to configure the easy servo drive as follows, depending on the
specific drive.

There is a 2-bit DIP switch on the ES-D508 which can be used to reverse the default motion direction
and perform motor self-test.
SW1 is used to reverse the
default motion direction.
Set SW2 on to activate
the motor self-test.
ES-D808 / ES-D1008
There is a 6-bit DIP switch on the ES-D808 or ES-D1008 drive. SW1 to SW4 are used to set the micro
step resolution and SW5 are used to set the default motion direction.

Rotating the Motor
Calculating Rotation Speed and Angle
You may also want to calculate the motor rotation speed and rotation angle, before commanding any
motion. If the pulse frequency and counts are known, they can be calculated as follows:
You can start the controller or pulse generator to rotate the motor. Actually, any device which gives
high-to-low or low-to-high level changes can be used to move the motor. If it is your first time
installation, it is recommended to disconnect the motor shaft from the load in case of accident. You
can start from low pulse frequency then going to high. One triggered edge of the pulse makes the
motor move one micro angle. There are no minimum speed limits for the ES servos, however the
maximum running speed will be determined by the input voltage, current settings or maximum input
frequency of the drive.
Rotating the Motor in Self-test Mode
When the drive is configured in self-test mode by setting the SW2 to the ON position, the connecting
motor will rotates 1 revolution CW and 1 revolution CCW then repeat, until you set the SW2 to the
OFF position.
Rotating the Motor in PC Software
There is a simple emulating controller that is used for self-test in the ES-D drive. It is not a full
functionality controller, but it do eliminates the troubles to setup an external motion controller when
you want to test the ES drives or verify the connection in case of problem. However, the
performance in the emulating controller DOES NOT represent that of using an external motion
controller.
16
Page 21
Hardware Manual of the ES-D Series Drives
Click Drive Settings->Current Loop / Motion Test to open the test window. Then click the Motion Test tab to open the emulating controller. Edit the trapezoidal velocity profile and click the Start
button to execute the motion.
Power Supply Selection
To achieve good driving performances, it is important to choose a suitable supply voltage and use a
matching current value. 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.
Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the drive. If regulated power
supplies (such as most switching supplies.) are indeed used, it is important to have large current
output rating to avoid problems like current clamp, for example using 4A supply for 3A motor-drive
operation. 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 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.
17
Page 22
Hardware Manual of the ES-D Series Drives
Multiple Drives
It is recommended to have multiple drives to share one power supply to reduce cost, if the supply
has enough capacity. To avoid cross interference, DO NOT daisy-chain the power supply input pins of
the drives. Instead, please connect them to power supply separately.
Selecting Supply Voltage
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, and it is suggested to use power supplies
with theoretical output voltage of drive’s minimum + 10% to drive’s maximum – 10%, leaving room
for power fluctuation and back-EMF.

Control Signal Setup Timing
To make a reliable operation, the ES drive requires the control signals to meet the setup time
requirements as follows. Otherwise losing of steps may happen.
Leadshine’s easy servo motor is integrated with a high-resolution 1,000-line optical incremental
encoder. That encoder can send the real-time shaft position back to the ES-D drive. Like traditional
servo controls, the drive can automatically adjust the output current to the motor. The output
current ranges between the holding current and the close-loop current. When there is no pulse sent
to the drive, the ES-D drive goes into idle mode and the actual motor current is determined by the
holding current percentage (similar to “ idle current” of open loop stepper drives). In normal working
mode, the ES monitors the actual shaft position all the time. The current outputted to the motor
changes dynamically based on the tracking error between the actual position and the commanded
position.
Low holding current can reduce motor heating, however also reduces the holding torque which is
used to lock the motor shaft at standstill. It is recommended to determine the holding current by
whether or not there is big vibration at start-up and how much lock torque is required, based on your
actual applications.

Time(s) of Blink
Fine Tuning
Leadshine already loads default current-loop parameters and position-loop parameters. Those
default parameter values have been optimized. They should be good enough for most industrial
applications, and there is no need to tune them. However, if you want to fine tune the ES for best
performance for your applications, Leadshine also offers tuning software, ProTuner, which allows you
to adjust those current-loop and position-loop parameters (see software manual).
Protection Functions
To improve reliability, the ES-D drive incorporates some built-in protection functions. The ES-D drive
uses one red LED to indicate the protection type. The periodic time is 5 s (seconds), and the blinking
times of red LED indicates what protection has been activated. Because only one protection can be
displayed by red LED, so the drive will decide what error to display according to their priorities. See
the following protection Indications table for displaying priorities.

When input voltage including voltage fluctuation and back EMF of the motor exceeds the limits,
protection will be activated and red LED will blink twice within each periodic time.
!
Caution
When above protections are active, the motor shaft will be free and the LED will
blinks. Reset the drive by repowering it to make it function properly after
removing above problems. Since there is no protection against power leads (﹢,﹣) reversal, it is critical to make sure that power supply leads correctly connected
to drive. Otherwise, the drive will be damaged instantly.

Frequently Asked Questions
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.
