Be sure to conduct wiring properly and securely. Insecure or improper wiring may cause the mo-
tor running out of control or being damaged from overheating. In addition, pay attention not to al-
low conductive materials, such as wire chips, entering the driver during the installation and wiring.
• Secure the screws and earth screw on the terminal block with the torque specified in the specifi
-
cation.
• When establishing a system using safety functions, completely understand the applicable safety
standards and the operating instruction manual or technical documents for the product.
• Never make an approach to the motor and the machines driven by the motor while power is ap
-
plied because they may become failure or malfunction.
• Do not use servo-on signal (SRV-ON) as the start/stop signal. Doing so may damage the built-in
dynamic brake circuit in the driver.
• Pay attention to the heat dissipation. The driver will generate heat while the motor is in opera
-
tion. Using the driver in a sealed control box may cause an abnormal heating of the control
box. A proper consideration should be given to cool the driver so that the ambient temperature
matches the specified operating temperature range.
• There is a possibility that the motor will be damaged by heat or emit smoke or dust due to a fault
in the motor itself or the driver coupled with it. A proper consideration should be given if the mo-
tor is used in a clean room or similar environment.
• If the dynamic brake is applied during operation at a high speed, provide approx. 10-minute
dwell period.
Restarting the motor earlier may cause a broken wire in the dynamic brake making the brake in-
operable.
• The capacitance of capacitor in the power supply rectifier circuit decreases its capacitance with
age.
To prevent a secondary accident due to malfunction, it should be replaced with new one after
5-year use.
Replacement should be performed by us or our authorized distributor.
• Before using the product, be sure to read the instruction manual (Safety part).
Recommended Electric Wires for Driver
• For the main circuit, use electric wire that withstands at least 600 VAC with tempera
-
ture rating 75
˚C
or higher.
• When using bundled wires running through metallic conduit, the amounts of current
determined according to the reduction rate must be subtracted from the nominal allow-
able current.
• Electric wires
<In high ambient temperature>
Use heat resistant wire.
Common polyvinyl chloride wires will deteriorate by heat at a higher rate.
<In low ambient temperature>
The surface of vinyl chloride insulation becomes hardened and brittle at low tempera-
ture and needs specific protective measure when used in cold region.
• Bend radius of the cable must be 10 times or more its finish outside diameter.
• Cables cannot be used for continuous regeneration because they are not designed for
such application.
