Safety Precautions
■ Do not connect the servomotor directly to the local electrical network.
Failure to observe this may result in damage to servomotor.
■ Do not plug or unplug connectors from servo drivewhen power is on.
Failure to observe this may result in damage to servo drive and servomotor.
■Please note that even after power is removed, residual voltage still remains in the capacitor inside the servo drive. If
inspection is to be performed after power is removed, please wait 5 minutes to avoid risk of electrical shock.
■Keep servo drives and other devices separated by at least 10mm.
The servo drive generates heat. Install the servo drive so that it can radiate heat freely. When installing servo drives
with other devices in a control panel, provide at least 10mm space between them and 50mm space above and below
them.Please install servo drives in an environment free from condensation, vibration and shock.
■Perform noise reduction and grounding properly.
Please comply with the following instructions to avoid noise generated by signal lines.
1. Separate high-voltage cables from low-voltage cables.
2. Use cables as short as possible.
3. Single point grounding is required for the servomotor and servo drive (grounding resistance 100mΩ or below).
4. Never use a line filter for the motor's power supply in the circuit.
■Conduct a voltage resistance test for the servo drive under the following conditions:
1. Input voltage:AC 1500Vrms, 1 minute
2. Braking current:100mA
3. Frequency:50/60Hz
4. Voltage applied point:Between L1, L2,L3 terminals and frame ground.
■Use a fast-response type ground-fault interrupter.
For a ground-fault interrupter, always use a fast-response type or one designed for PWM inverters. Do not use a
time-delay type.
■ Do not make any extreme adjustments or setting changes of parameters.
Failure to observe this caution may result in injury or damage to the product due to unstable operation.
■The servomotor cannot be operated by turning the power on and off.
Frequently turning the power ON and OFF causes the internal circuit elements to deteriorate, resulting in unexpected
problems.Always start or stop the servomotor by using reference pulses.
■Follow the instructions for PCB use:
1.Before touch the PCB,the body of the user must be discharged.
2.The PCB cannot be contact with highly insulating materials.
3.The PCB is only allowed to put on the conductive pad.
4.The PCB is only allowed to store and transport packaging in conductive wrapper or conductive foam rubber or
aluminum foil.
■ Precautions on turning ON and turning OFF the servo drive:
1.When turning on the servo drive, make sure that the control power supply has be turned on before turningon the main
circuit power supply.
2.When turning off the servo drive, make sure that the main circuit power supply has be turned off before turningoff the
control power supply.

Notes on installation
When installed in a control
panel
Design the control panel size, unit layout, and cooling method so that the temperature
around the periphery of the servo drive does not exceed 55℃.
When installed near a
heating unit
Suppress radiation heat from the heating unit and a temperature rise caused by
convection so that the temperature around the periphery of the servo drive does not
exceed 55℃.
When installed near a
source of vibration
Install a vibration isolator underneath the servo drive to prevent it from receiving vibration.
When installed in a location
subject to corrosive gases
Take appropriate action to prevent corrosive gases. Corrosive gases do not immediately
affect the servo drive, but will eventually cause contactor-related devices to malfunction.
Others
Avoid installation in a hot and humid site or where excessive dust or iron powder is
present in the air.
When connecting the cables, the bending radius should not be too small, do not bend or apply tension to cables.
Since the conductor of a signal cable is very thin (0.2 mm or 0.3 mm), handle it with adequate care.
2.1.7 Install to the Client
When the servo motor is mounted to the client, please firmly secure the servo motor by the screws with backing ring
as shown in the figure.
2.2 Servo Drive
ProNet series servo drive is a base-mounted type. Incorrect installation will cause problems. Always observe the
installation instructions described below.
2.2.1 Storage
When the servomotor is not being used, store it in an area with a temperature between -25℃ and 85℃ with the
power cable disconnected.
2.2.2 Installation Sites

Install the servo drive perpendicular to the wall as shown in the figure. The servo drive must be oriented this way
because it is designed to be cooled by natural convection or a cooling fan if required. Firmly secure the servo drive
through two mounting holes.
2.2.4 Installation Method
When installing multiple servo drives side by side in a control panel, observe the following installation method.
■Installation Orientation
Install servo drive perpendicular to the wall so that the front panel (containing connectors) faces outward.
■Cooling
Provide sufficient space around each servo drive to allow cooling by natural convection or fans.
■Installing side by side
When installing servo drives side by side, provide at least 10mm space between each individual servo drive and at
least 50mm space above and below each one as well as shown in the figure above. Ensure the temperature inside the
control panel is evenly distributed, and prevent the temperature around each servo drive from increasing excessively.

3.1 Main Circuit Wiring
!
CAUTION
·Do not bundle or run power and signal lines together in the same duct. Keep power andsignallines
separated by at least 300 mm.
·Use twisted-pair shielded wires or multi-core twisted-pair shielded wires for signal and encoder feedback
lines.
·The maximum length is 3 m for reference input lines and 20 m for encoder feedback lines.
·Do not touch the power terminals for 5 minutes after turning power OFF because high voltage may still
remain in the servo drive.

3.2.4 Interface Circuit
This section shows examples of servo drive I/O signal connection to the host controller.
■Interface for Analog Reference Input Circuit
Analog signals are either speed or torque reference signals at about 40kΩimpedance, and the maximum allowable
voltages for input signals is ±10V.
Reference speed input Reference torque input
■Interface for Sequence Input Circuit
The sequence input circuit interface connects through a relay or open-collector transistor circuit.Select a low-current relay
otherwise a faulty contact will result.

Relay
The amount of two-phase (phase A and phase B) pulse output signals (PAO,/PAO,PBO,/PBO) and zero-point pulse
signals(PCO,/PCO) are output via line-driver output circuits.Normally, the servo drive uses this output circuit in speed
control to comprise the position control system at the host controller. Connect the line-driver output circuit through a line
receiver circuit at the host controller.
■Interface for Sequence Output Circuit
Photocoupler output circuits are used for Servo Alarm (ALM), Servo Ready(S-RDY), and other sequence output signal
circuits.Connect a photocoupler output circuit through a relay circuit.
Allocable signals are as following:

3.6.1 Noise Control
The servodrive uses high-speed switching elements in the main circuit. It may receive "switching noise"from these
high-speed switching elements.
To prevent malfunction due to noise, take the following actions:
• Position the input reference device and noise filter as close to the servo drive as possible.
• Always install a surge absorber in the relay, solenoid and electromagnetic contactor coils.
• The distance between a power line (servomotor main circuit cable) and a signal line must be at least 30 cm.Do not put
the power and signal lines in the same duct or bundle them together.
• Do not share the power supply with an electric welder or electrical discharge machine. When the servo drive is placed
near a high-frequency generator, install a noise filter on the input side of the power supplyline. As for the wiring of noise
filter, refer to (1) Noise Filter shown below.
• For proper grounding technique, refer to (2) Correct Grounding.
(1) Noise Filter
Please install a noise filter in the appropriate place to protect the servo drive from external noise interference.
Notice:
•For ground wires connected to the ground plate, use a thick wire with a thickness of at least 3.5 mm2 (preferably, plain
stitch cooper wire)
•should be twisted-pair wires.
•When using a noise filter, follow the precautions in 3.6.2 Precautions on Connecting Noise Filter.

Take the following grounding measures to prevent the servo drive from malfunctioning due to noise.
■ Grounding the Motor Frame
If the servomotor is grounded via the machine, a switching noise current will flow from the servo drive main circuit through
the servomotor stray capacitance.
Always connect servomotor frame terminal FG to the servodrive ground terminal. Also be sure to ground the ground
terminal .
■ Noise on the I/O Signal Line
If the I/O signal line receives noise, ground the 0 V line (SG) of the reference input line. If the main circuit wiring for the
motor is accommodated in a metal conduit, ground the conduit and its junction box. For all grounding, ground at one point
only.
(3)Precautions on Installing on the Control Panel
■When the servo drive is installed on the control panel, a piece of metal plate should be fixed. It is used for fixing the servo
drive and other peripheral devices. The noise filter should be installed on the metal plate, and closed to the hole drill
through power lines on control panel. Use screws to fix the noise filter to the metal plate. The grounding terminals of noise
filter connects to the grounding terminals of control panel.
■Servo drive should be fixed on a piece of metal plate. Make sure the heat sink towards ground. The grounding terminals
of servo drive connect to the grounding terminals of control panel.
3.6.2 Precautions on Connecting Noise Filter
(1) Noise Filter Brake Power Supply
Use the noise filter Manufactured by SCHAFFNER at the brake power input for servomotors with holding brakes.
Relationship between servo drive power and noise filter current:
Note:
1. A single-phase servomotor should apply a two-phase filter. A three-phase servo drive should apply a
three-phase filter.
2. Choose the right filter according the specifications of operating voltage, current, and manufacturer.
3. Recommended noise filter of 400V servo drive:

(1) Zero Clamp Function
The zero clamp function is used for systems where the host controller does not form a position loop for the speed
reference input. When the zero clamp signal (/P-CON) is ON, a position loop is formed inside the servo drive as soon as
the input voltage of the speed reference (V-REF) drops below the servomotor zero clamp speed. The servomotor ignores
the speed reference and quickly stops and locks the servomotor.
The servomotor is clamped within ±1 pulse when the zero clamp function is turned ON, and will still return to the zero
clamp position even if it is forcibly rotated by an external force.

(1) Note:
For the low rigidity load, low frequency vibration will occur continually at the front end of the load during fast acceleration
or fast deceleration. The vibration may delay positioning time and affect the productive efficiency.
The function of low frequency vibration suppression is embedded in ProNet series servo drives by calculating the load
position and compensating.
(2) Application:
Low frequency vibration suppression function is enabled in both speed control mode and position control mode.
Low frequency vibration suppression function is disabled or can not reach the expected effect in the following conditions.
Vibration is pricked up due to an external force.
Vibration frequency is between5.0Hz to 50.0Hz.
There is mechanical clearance at the mechanical connection part.
The time for movement is less than one vibration period.
(3) How to operate:
Measuring Vibration frequency
Write the frequency data measured(unit:0.1Hz) directly to Parameter Pn411, if the vibration frequency can be
measured by an instrument (such as a laser interferometer).And it also can be measured indirectly by
communication software ESView or FFT analsis function.

4.6.8 Position Control (contact reference)
Position control under contact reference (parameter Pn005.1=C). In this mode, servo drive can position with a single
axes without a host controller.
There are 16 position control points with each being able to set move distance, running speed, constants for position
reference filter time, and the stop time when positioning completed. Two speeds (1. speed moving toward distance switch
“speed of looking for reference point”. 2. Speed moving away from distance switch “moving speed.”) of reference points
could be set as:
Two position modes: 1. Absolute position mode 2. Relative position mode
Two running modes: 1. Circling mode 2. Non-circling mode
Two step switching method: 1. Delay step switching 2. /P-CON signal switching
Method of looking for reference points: 1. Forward direction 2. Reverse direction
■Adjusting offset
Offset of each points has two correspondent parameters: one unit of the parameter is 【x 10000 reference pulse】and the
other is 【x 1 reference pulse】. Setting range of both parameters is: (-9999----+9999), while offset value equals sum of
those two values.
For example:
No.0 offset correspond to parameter Pn600【x 10000 reference pulse】 and Pn601【x 1 reference pulse】. Set Pn600
= 100, Pn601=-100.
No.0 offset value = Pn600x10000 reference pulse + Pn601x1 reference pulse
= 100x10000 reference pulse + (-100)x1 reference pulse
= 999900 reference pulse
With the same principle, we can conclude: in order to get the same results, we also can set Pn600 = 99 and Pn601 =
9900.
Thus, we can see when the two parameters are not zero; we can get same result by two ways: one is to set the two
parameters both negative or both positive, or one negative the other positive.
■Speed
Speed mentioned here refers to the steady speed during which the motor is running, which is similar to the pulse
frequency given from the external pulse reference in position control.However, this speed has nothing to do with the
electronic gear; it is the actual speed of the motor.
■Position reference filter time constant
Same as position reference filter time constant Pn204 in common position control.

Apply internal delay to change steps to a valid value in parameter Pn681.1.
Time for change steps outputs from positioning completed signal CON/, from Servo ON, or from the time when reference
point is found till the Servo performs the program to control position of the point. Such period of time depends on step
changing time required by a point number among start point in program.
When running point control program, if error counter is set as “not clear error counter when Servo OFF”, then the error
counter might flood. If it does not flood, then the servo drive will probably run at the max. running speed when Servo ON
again. PLEASE PAY ATTENTION TO THE SAFETY OF INSTRUMENT.
■Looking for the reference point
Looking for the reference point is for establishing a zero physical point of the operating platform, which is used as zero
point in the coordinates during point position control. And users may choose to find a reference point either in forward or
reverse side.
How to find a reference point
Mount a limit switch in the forward or reverse side.Find a reference point in the forward direction after connecting to /PCL
and in the reverse direction after connecting to /NCL. When the operating platform bumps into the limit the switch, the
motor will first stop according to the way set by Pn004.0, and then rotate again against limit the switch. When the
operating platform leaves the limit switch and the motor reaches the position of first photo encoder Phase C pulse,then
position of operating platform is set to be the zero point of the coordinates.
How to find related parameters of reference point
Speed towards limit switch is called “speed of looking for reference point “, and the moving speed away from limit switch is
called “ moving speed”. These two speeds could be set by the following parameters:
Usually, the set speed of the reference point (Pn685) is high, and the moving speed (Pn686) is low. Note: if moving speed
is too high, precision of finding a reference point would be affected.
When looking for a reference point, /PCL and /NCL are no longer programmed to limit external current.

In position control mode, the servomotor always needs to operate at a fixed position. This position is normally regarded as
the zero position. When the host controller is turned on, the zero position adjustment is required before processing. This
zero position will be regarded as the reference point. ESTUN servo drives can perform this function by the homing
function.

Allocating HomingOutput Signal (/HOME)
(4)Description of Homing Operation
Please set Pn689 according to the actual operation in position control mode. When starting the homing function, the
servomotor will run at the speed of Pn685 when detecting the rising edge of SHOM signal; the servomotor will run at the
speed of Pn686 according to the setting of Pn689.1 when detecting the valid ORG signal.
When input ORG and the encoder C-Pulse is being detected, the servo drive will begin to calculate the number of homing
offset pulses. When offset pulses is completed, the servomotor stops and outputs homing completion signal /HOME, then
homing control is completed.
Pn685 (Hitting the origin signal (ORG)) is usually set at high speed, Pn686 (Leaving the origin signal ORG) is usually set
at low speed.
Please be attention that if Pn686 is setting too high, the precision of mechanical zero position will be affected.
After hitting the origin signal ORG, the motor will return to find C-pulse; the figure is shown as below:
