Operation - YASKAWA S-V Series Safety Precautions

Operation

• Conduct trial operation on the servomotor alone with the motor
shaft disconnected from machine to avoid any unexpected acci-
dents.
Failure to observe this caution may result in injury.
• Before starting operation with a machine connected, change the
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.
• Avoid frequently turning power ON and OFF.
Since the SERVOPACK has a capacitor in the power supply, a high
charging current flows when power is turned ON. Frequently turning
power ON and OFF causes main power devices like capacitors and
fuses to deteriorate, resulting in unexpected problems.
• Forced stop function with forward/reverse overtravel is not effec-
tive during JOG mode operation using utility function Fn002 and
zero point search using Fn003.
• When using the servomotor for a vertical axis, install the safety
devices to prevent workpieces to fall off due to occurrence of
alarm or overtravel. Set the servomotor so that it will stop in the
zero clamp state at occurrence of overtravel.
Failure to observe this caution may cause workpieces to fall off due to
overtravel.
• When not using the tuning-less function, set to the correct
moment of inertia ratio Pn103.
Setting to an incorrect moment of inertia ratio may cause vibration.
• Do not touch the SERVOPACK heatsinks, 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 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
product due to unstable operation.
