Operation
Maintenance and Inspection
CAUTION
• Do not stand within the machine's range of motion during operation.
Failure to observe this caution may result in injury.
• Always use the servomotor and SERVOPACK in one of the specified combinations.
Failure to observe this caution may result in fire or malfunction.
• Before operation, install a limit switch or stopper on
the end of the slider to prevent unexpected
movement.
Failure to observe this caution may result in injury.
• During trial operation, confirm that the holding
brake works correctly. Furthermore, secure system
safety against problems such as signal line disconnection.
• Before starting operation with a machine connected, cha
nge the parameter settings to match the
parameters of the machine.
Starting operation without matching
the proper settings may cause the machine to run out of control or mal-
function.
• Do not turn the power ON and OF
F more than necessary.
Do not use the SERVOPACK for applications that require the power to turn ON and OFF frequently. Such
applications will cause elements in the SERVOPACK to deteriorate.
As a guideline, at least one hour should be allowed between the power being turned ON and OFF once actual
operation has been started.
• When carrying out JOG operation (Fn002), origin search (Fn
003), or EasyFFT (Fn206), forcing
movable machine parts to stop does not work for forward overtravel or reverse overtravel. Take
necessary precautions.
Failure to observe this caution may result in damage to the equipment.
• When using the servomotor for a vertical axis, install sa
fety devices to prevent workpieces from fall-
ing due to alarms or overtravels. Set the
servomotor so that it will stop in the zero clamp state when
overtravel occurs.
Failure to observe this cautio
n may cause workpieces to fall due to overtravel.
• When not using the turning-less function, set the correct mass ratio (Pn103).
Setting an incorrect mass ratio may cause machine vibration.
• Do not touch the SERVOPACK heat sinks, regenerative
resistor, or servomotor while power is ON
or soon after the power is turned OFF.
Failure to observe this caution may result
in burns due to high temperatures.
• Do not make any extreme adjustments or setting changes of parameters.
Failure to observe this caution may result in injury
or damage to the equipment due to unstable operation.
• If an alarm occurs, shut down the main circuit power supply.
Failure to observe this caution may result in fire due to r
egenerative resistor overheating caused by regenera-
tive transistor failure.
• When an alarm occurs, remove the cause, reset the a
larm after confirming safety, and then resume
operation.
Failure to observe this caution may result in
damage to the equipment, fire, or injury.
• 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 stop t
he current process and stop the system.
CAUTION
• Do not disassemble the SERVOPACK and the servomotor.
Failure to observe this caution may result in electric shock or injury.
• Do not attempt to change wiring while the power is ON.
Failure to observe this caution may result in electric shock or injury.
• When replacing the SERVOPACK, resume operation only after copying the previous SERVOPACK
p
arameters to the new SERVOPACK.
Failure to observe this caution may result in damage
to the equipment.
