SAFETY PRECAUTIONS B-65232EN/03
s-4
WARNING
- Connect power wires securely so that they will not get loose.
A failure to observe this caution may cause a wire to be
disconnected, resulting in a ground fault, short circuit, or electric
shock.
- Do not supply the power to the motor while any terminal is
exposed.
A failure to observe this caution is very dangerous because you
may get electric shocks if your body or any conductive stuff
touches an exposed terminal.
- Do not get close to a rotary section of a motor when it is
rotating.
A rotating part may catch your cloths or fingers. Before starting a
motor, ensure that there is no stuff that can fly away (such as a
key) on the motor.
- Before touching a motor, shut off the power to it.
Even if a motor is not rotating, there may be a voltage across the
terminals of the motor.
Especially before touching a power supply connection, take
sufficient precautions.
Otherwise you may get electric shocks.
- Do not touch any terminal of a motor for a while (at least 5
minutes) after the power to the motor is shut off.
High voltage remains across power line terminals of a motor for a
while after the power to the motor is shut off. So, do not touch any
terminal or connect it to any other equipment. Otherwise, you may
get electric shocks or the motor and/or equipment may get
damaged.
- To drive a motor, use a specified amplifier and parameters.
An incorrect combination of a motor, amplifier, and parameters
may cause the motor to behave unexpectedly. This is dangerous,
and the motor may get damaged.
- Do not touch a regenerative discharge unit for a while (at
least 30 minutes) after the power to the motor is shut off.
A regenerative discharge unit may get hot when the motor is
running.
Do not touch the regenerative discharge unit before it gets cool
enough. Otherwise, you may get burned.
- Do not touch a motor when it is running or immediately after
it stops.
A motor may get hot when it is running. Do not touch the motor
before it gets cool enough. Otherwise, you may get burned.
