Operation Precautions
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.
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, Origin Search, or Easy FFT
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.
