Specific Product Precautions 2
Be sure to read before handling. Refer to back cover for Safety Instructions.
For Electric Actuator Precautions, refer to "Handling Precautions for SMC Products"
and the Operation Manual on SMC website, http://www.smcworld.com
Power Supply
Caution
1. Use a power supply with low noise between lines and
between power and ground.
In cases where noise is high, use an isolation transformer.
2. Take appropriate measures to prevent surges from
lightning. Ground the surge absorber for lightning
separately from the grounding of the driver and its
peripheral devices.
Wiring
Warning
1. The driver will be damaged if a commercial power
supply (100V/200V) is added to the driver
power (U, V, W). Be sure to check wiring such as wiring
mistakes when the power supply is turned on.
2. Connect the ends of the U, V, W wires from the motor
cable correctly to the phases (U, V, W) of the servo
motor power. If these wires do not match up, it is
unable to control the servo motor.
Grounding
Warning
1. For grounding actuator, connect the copper wire of the
,
actuator to the driver s protective earth (PE) terminal and
connect the copper wire of the driver to the earth via the
,
control panel s protective earth (PE) terminal.
Do not connect them directly to the control panel
protective earth (PE) terminal.

2. In the unlikely event that malfunction is caused by the
ground, it may be disconnected.

Maintenance
Warning
1. Perform maintenance checks periodically.
Confirm wiring and screws are not loose.
Loose screws or wires may cause unexpected malfunction.
2. Conduct an appropriate functional inspection and test
after completed maintenance.
In case of any abnormalities (if the actuator does not move or the
equipment does not operate properly, etc.), stop the operation of
the system.
Otherwise, unexpected malfunction may occur and safety cannot
be assured.
Conduct a test of the emergency stop to confirm the safety of the
equipment.
3. Do not disassemble, modify or repair the driver or its
peripheral devices.
4. Do not put anything conductive or flammable inside
the driver.
Otherwise, fire can result.
5. Do not conduct an insulation resistance test or
insulation withstand voltage test.
6. Reserve sufficient space for maintenance.
Design the system so that it allows required space for
maintenance.
