Chapter 1 Safety Information and Precautions
This manual includes notices you have to observe in order to ensure your personal safety and
prevent property damages. These notices shown below are graded according to the degree of
danger.
It indicates that failure to comply with the notice may result in a
severe personal injury or even death.
It indicates that failure to comply with the notice may result in a
minor or moderate personal injury or equipment damage.
1.1 General Safety
This section describes precautions on acceptance, storage, transportation, installation, wiring,
running, inspection, and disposal of the product.
DANGER
u
After the power is off for ve minutes and the power indicator turns off, measure and check the voltage between
and
using a multimeter, and then install or uninstall the drive. Otherwise, you may get an electric shock
due to residual voltage.
u
Use the power from the TN/TT grid rather than the IT grid for the drive. Failure to comply may result in electric shocks.
u
Do not touch the internal components of the drive. Failure to comply may result in electric shocks.
u
Insulate connection parts of the power terminals. Failure to comply may result in electric shocks.
u
Ground the terminal of the drive (D-class grounding). Failure to comply may result in electric shocks.
u
Do not damage the cables, lay them under large tension or pressure, or hang them. Failure to comply may result
in equipment stop or damages.
u
Only specied persons are allowed to set, uninstall, and repair the drive. Failure to comply may result in electric
shocks or personal injuries.
u
Do not remove the cover, cables, connectors, or options when the drive is live. Failure to comply may result in
electric shocks.
u
Perform a trial run according to the procedure required in the manual.
u
Improper operations when the servo motor is connected to the drive result in mechanical damages and even
personal injuries.
u
Do not change the maximum speed (H00-15) except for special purpose. Changing this value improperly may
cause mechanical damages or personal injuryies.
u
After power-on or within a short time after power-off, do not touch the heatsink of the servo drive, external
regenerative resistor, or servo motor as they may get very hot and there is a risk of burns. Take safety measures,
for example, installing the housing, to prevent hands or components such as cables from contacting these high-
temperature components.
u
Avoid contact with the rotating part of the servo motor when it is running. Failure to comply may result in
personal injuries.
u
Before operating the equipment, enable emergency stop of the connected servo motor. Failure to comply may
result in personal injuries.
u
Install a stop device on the mechanical side to ensure safety.
u
The brake (if available) of the servo motor is not used as the stop device. Lacking the stop device may result in
personal injuries.
u
The machine may restart if power supply is restored after an instantaneous power failure occurs when it is
running. Do not get close to the machine in this period.
u
Take measures to ensure personal safety at restart.
u
Do not alter the drive. Failure to comply may result in personal injuries or mechanical damages.
u
Install the servo drive, motor, and external regenerative resistor on incombustible objects. Failure to comply may
result in a re.
u
Connect the electromagnetic contactor and non-fuse circuit breaker between the power supply and main circuit
of the drive (L1 and L2 for single-phase; R, S, and T for three-phase). Otherwise, large current may not be cut off
when a fault occurs in the drive, resulting in a re.
u
Prevent combustible objects such as oil and grease and conductive objects such as screw and metal sheet from
entry into the servo drive and motor. Failure to comply may result in a re.
