NOTICE!
– Whenever possible, use the Cables specified by Yaskawa.
If you use any other cables, confirm the rated current and appli-
cation 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 Signal 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-current 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 bat-
teries, 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.
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 discon-
nect 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 motor will coast to a stop or stop
with the dynamic brake according to a setting in the SERVO-
PACK. The coasting distance will change with the moment of
inertia of the load. Check the coasting distance during trial oper-
ation 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.
