Safety Precautions [Make sure to follow.]
4
Caution
There is no safeguard on the motor. Use an
over-voltage safeguard, short-circuit breaker,
overheating safeguard, and emergency stop
to ensure safe operation.
Injury or fire could otherwise result.
Do not touch the radiation fin of the amplifier,
the regenerative resistor, or the motor while
the device is powered up, or immediately after
switching the power off, as these parts
generate excessive heat.
Burn could otherwise result.
In the case of any irregular operation, stop the
device immediately.
Electric shock, injury or fire could
otherwise result.
Do not perform extensive adjustments to the
device as they may result in unstable
operation.
Bodily injury could otherwise result.
Trial runs should be performed with the motor
in a fixed position, separated from the
mechanism. After verifying successful
operation, install the motor on the mechanism.
Bodily injury could otherwise result.
The holding brake is not to be used as a
safety stop for the mechanism. Install a safety
stop device on the mechanism.
Bodily injury could otherwise result.
In the case of an alarm, first remove the cause
of the alarm, and then verify safety. Next, reset
the alarm and restart the device.
Bodily injury could otherwise result.
Make sure the input power supply voltage is in
or less than the specification range.
Damage to the device could
otherwise result
Avoid getting close to the device, as a
momentary power outage could cause it to
suddenly restart (although it is designed to be
safe even in the case of a sudden restart).
Bodily injury could otherwise result.
Standard specification servo amplifiers have a
dynamic brake resistor. Do not rotate the
motor continuously from the outside when the
amplifier is not powered on, because the
dynamic brake resistor will heat up, and can
be dangerous.
Fire or burn could otherwise result.
Be careful during maintenance and inspection,
as the body of the amplifier becomes hot.
Burn could otherwise result.
It is recommended to replace the electrolytic
capacitors in the amplifier after 5 years, if used
at an average temperature of 40°C year round.
Damage to the device could
otherwise result.
