DANGER
Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
WARNING
Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
Check all wiring and power supplies carefully.
Incorrect wiring or incorrect voltage application to the output circuits may cause short-circuit fail-
ures. If a short-circuit failure occurs as a result of any of these causes, the holding brake will not
work. This could damage the machine or cause an accident that may result in death or injury.
Connect the AC and DC power supplies to the specified SERVOPACK terminals.
•Connect an AC power supply to the L1, L2, and L3 terminals and the L1C and L2C terminals on the
SERVOPACK.
•Connect a DC power supply to the B1/ and 2 terminals and the L1C and L2C terminals on the
SERVOPACK.
There is a risk of failure or fire.
If you use a SERVOPACK with the Dynamic Brake Hardware Option, connect an External
Dynamic Brake Resistor that is suitable for the machine and equipment specifications to the
specified terminals.
There is a risk of unexpected operation, machine damage, burning, or injury when an emergency
stop is performed.

xix
CAUTION
Wait for at least six minutes after turning OFF the power supply (with a SERVOPACK for a 100-
VAC input, wait for at least nine minutes) and then make sure that the CHARGE indicator is not
lit before starting wiring or inspection work. Do not touch the power supply terminals while the
CHARGE lamp is lit after turning OFF the power supply because high voltage may still remain in
the SERVOPACK.
There is a risk of electric shock.
Observe the precautions and instructions for wiring and trial operation precisely as described in
this document.
Failures caused by incorrect wiring or incorrect voltage application in the brake circuit may cause
the SERVOPACK to fail, damage the equipment, or cause an accident resulting in death or injury.
Check the wiring to be sure it has been performed correctly.
Connectors and pin layouts are sometimes different for different models. Always confirm the pin
layouts in technical documents for your model before operation.
There is a risk of failure or malfunction.
Connect wires to power supply terminals and motor connection terminals securely with the
specified methods and tightening torque.
Insufficient tightening may cause wires and terminal blocks to generate heat due to faulty contact,
possibly resulting in fire.
Use shielded twisted-pair cables or screened unshielded multi-twisted-pair cables for I/O Sig-
nal Cables and Encoder Cables.
Observe the following precautions when wiring the SERVOPACK’s main circuit terminals.
•Turn ON the power supply to the SERVOPACK only after all wiring, including the main circuit termi-
nals, has been completed.
•If a connector is used for the main circuit terminals, remove the main circuit connector from the SER-
VOPACK before you wire it.
•Insert only one wire per insertion hole in the main circuit terminals.
•When you insert a wire, make sure that the conductor wire (e.g., whiskers) does not come into con-
tact with adjacent wires.
Install molded-case circuit breakers and other safety measures to provide protection against
short circuits in external wiring.
There is a risk of fire or failure.
NOTICE
Whenever possible, use the Cables specified by Yaskawa.
If you use any other cables, confirm the rated current and application environment of your model
and use the wiring materials specified by Yaskawa or equivalent materials.
Securely tighten cable connector screws and lock mechanisms.
Insufficient tightening may result in cable connectors falling off during operation.
Do not bundle power lines (e.g., the Main Circuit Cable) and low-current lines (e.g., the I/O Sig-
nal Cables or Encoder Cables) together or run them through the same duct. If you do not place
power lines and low-current lines in separate ducts, separate them by at least 30 cm.
If the cables are too close to each other, malfunctions may occur due to noise affecting the low-cur-
rent lines.
Install a battery at either the host controller or on the Encoder Cable.
If you install batteries both at the host controller and on the Encoder Cable at the same time, you
will create a loop circuit between the batteries, resulting in a risk of damage or burning.
When connecting a battery, connect the polarity correctly.
There is a risk of battery rupture or encoder failure.

Operation Precautions
WARNING
Before starting operation with a machine connected, change the settings of the switches and
parameters to match the machine.
Unexpected machine operation, failure, or personal injury may occur if operation is started before
appropriate settings are made.
Do not radically change the settings of the parameters.
There is a risk of unstable operation, machine damage, or injury.
Install limit switches or stoppers at the ends of the moving parts of the machine to prevent
unexpected accidents.
There is a risk of machine damage or injury.
For trial operation, securely mount the Servomotor and disconnect it from the machine.
There is a risk of injury.
Forcing the motor to stop for overtravel is disabled when the Jog (Fn002), Origin Search
(Fn003), or Easy FFT (Fn206) utility function is executed. Take necessary precautions.
There is a risk of machine damage or injury.
When an alarm occurs, the Servomotor will coast to a stop or stop with the dynamic brake
according to the SERVOPACK Option and settings. The coasting distance will change with the
moment of inertia of the load and the resistance of the External Dynamic Brake Resistor. Check
the coasting distance during trial operation and implement suitable safety measures on the
machine.
Do not enter the machine’s range of motion during operation.
There is a risk of injury.
Do not touch the moving parts of the Servomotor or machine during operation.
There is a risk of injury.
CAUTION
Design the system to ensure safety even when problems, such as broken signal lines, occur.
For example, the CCW-OT and CW-OT signals are set in the default settings to operate on the
safe side if a signal line breaks. Do not change the polarity of this type of signal.
When overtravel occurs, the power supply to the motor is turned OFF and the brake is released.
If you use the Servomotor to drive a vertical load, set the Servomotor to enter a zero-clamped
state after the Servomotor stops. Also, install safety devices (such as an external brake or
counterweight) to prevent the moving parts of the machine from falling.
Always turn OFF the servo before you turn OFF the power supply. If you turn OFF the main cir-
cuit power supply or control power supply during operation before you turn OFF the servo, the
Servomotor will stop as follows:
•If you turn OFF the main circuit power supply during operation without turning OFF the servo, the
Servomotor will stop abruptly with the dynamic brake.
•If you turn OFF the control power supply without turning OFF the servo, the stopping method that is
used by the Servomotor depends on the model of the SERVOPACK. For details, refer to the manual
for the SERVOPACK.
•If you use a SERVOPACK with the Dynamic Brake Hardware Option, the Servomotor stopping meth-
ods will be different from the stopping methods used without the Option or with other Hardware
Options. For details, refer to the following manual.
Σ-7-Series Σ-7S/Σ-7W SERVOPACK with Dynamic Brake Hardware Option Specifications Product Manual
(Manual No.: SIEP S800001 73)
Do not use the dynamic brake for any application other than an emergency stop.
There is a risk of failure due to rapid deterioration of elements in the SERVOPACK and the risk of
unexpected operation, machine damage, burning, or injury.
