SAFETY PRECAUTIONS B-65292EN/03
s-4
WARNING
- 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 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.
- Ensure that motors and related components are mounted securely.
If a motor or its component slips out of place or comes off when the
motor is running, it is very dangerous.
- When designing and assembling a machine tool, make it compliant with
EN60204-1.
To ensure the safety of the machine tool and satisfy European
standards, when designing and assembling a machine tool, make it
compliant with EN60204-1. For details of the standards, refer to the
standards.
