• During trial operation, confirm that the holding brake works cor-
rectly. Furthermore, secure system safety against problems such
as signal line disconnection.
• Before starting operation with a machine connected, change 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 malfunction.
• Do not turn the power ON and OFF 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
(Fn003), 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 safety
devices to prevent workpieces from falling due to alarms or over-
travels. Set the servomotor so that it will stop in the zero clamp
state when overtravel occurs.
Failure to observe this caution may cause workpieces to fall due to
overtravel.
• When not using the tuning-less function, set the correct moment
of inertia ratio (Pn103).
• Setting an incorrect moment of inertia ratio may cause machine vibra-
tion.
• Do not touch the SERVOPACK heat sinks 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 tempera-
tures.
• 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.
