•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.
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
Maintenance and Inspection 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
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.
NOTICE
Always measure the vibration of the Servomotor with the Servomotor mounted to the machine
and confirm that the vibration is within the allowable value.
If the vibration is too large, the Servomotor will be damage quickly and bolts may become loose.
When you adjust the gain during system commissioning, use a measuring instrument to monitor
the torque waveform and speed waveform and confirm that there is no vibration.
If a high gain causes vibration, the Servomotor will be damaged quickly.
An alarm or warning may occur if communications are performed with the host controller while
the SigmaWin+ or Digital Operator is operating.
If an alarm or warning occurs, it may interrupt the current process and stop the system.
DANGER
Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.

Troubleshooting Precautions
Disposal Precautions
General Precautions
WARNING
Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
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.
WARNING
The product may suddenly start to operate when the power supply is recovered after a momen-
tary power interruption. Design the machine to ensure human safety when operation restarts.
There is a risk of injury.
CAUTION
When an alarm occurs, remove the cause of the alarm and ensure safety. Then reset the alarm
or turn the power supply OFF and ON again to restart operation.
There is a risk of injury or machine damage.
If the Servo ON signal is input to the SERVOPACK and an alarm is reset, the Servomotor may
suddenly restart operation. Confirm that the servo is OFF and ensure safety before you reset an
alarm.
There is a risk of injury or machine damage.
If there is the possibility that an external force (including gravity) may move the current position
and create a hazardous situation when power is interrupted or an error occurs, install an exter-
nal braking mechanism that ensures safety.
When disposing of the product, treat it as ordinary industrial waste. However, local ordinances
and national laws must be observed. Implement all labeling and warnings as a final product as
