y
Do not remove the motor excitation during operation. Doing so may cause
the motor to stop and lose the holding force, resulting in injury or damage
to equipment.
Repair, disassembly and modification
y
Do not disassemble or modify the driver. Doing so may result in injury or
damage to equipment.
General
y
Do not use the driver beyond its specifications. Doing so may result in
electric shock, injury, or damage to equipment.
y
Keep your fingers and objects out of the openings in the driver. Failure to
do so may result in fire, electric shock or injury.
y
Do not touch the driver during operation or immediately after stopping.
Doing so may result in a skin burn(s).
Installation
y
Do not place combustibles around the driver. Doing so may result in fire or
skin burn(s).
y
Do not leave anything around the driver that would obstruct ventilation.
Doing so may result in damage to equipment.
Operation
y
Use a motor and driver only in the specified combination. An incorrect
combination may cause a fire.
y
Provide an emergency stop device or emergency stop circuit external to
the equipment so that the entire equipment will operate safely in the event
of a system failure or malfunction. Failure to do so may result in injury.
y
When moving the moving part manually, put the motor into a non-
excitation state. Continuing the work while the motor is in an excitation
state may result in injury.
y
For the main power supply, use a DC power supply with reinforced
insulation on its primary and secondary sides. Failure to do so may result in
electric shock.
y
Immediately when a problem occurred, stop operation and turn off the
main power supply. Failure to do so may result in fire, electric shock or
injury.
Precautions for use
This section covers restrictions and requirements the user should consider
when using the product.
•
Be sure to use our cables to connect a motor and a driver.
Refer to p.8 for the model name of cables.
•
When conducting the insulation resistance measurement, be
sure to separate the connection between the motor and the
driver.
Conducting the insulation resistance measurement with the motor and the
driver connected may result in damage to the product.
•
Note on connecting a power supply whose positive terminal is
grounded
The connectors CN1, CN2, CN3 and CN4 of the driver are not electrically
insulated. When grounding the positive terminal of the power supply, do
not connect any equipment (PC, etc.) whose negative terminal is grounded.
Doing so may cause the driver and these equipment to short, damaging both.
When connecting, do not ground equipment.
•
Saving data to the non-volatile memory
Do not turn off the main power supply while writing the data to the non-
volatile memory, and also do not turn off for 5 seconds after the completion
of writing the data.
Doing so may abort writing the data and cause an alarm of the EEPROM
error to generate. The non-volatile memory can be rewritten approximately
100,000 times.
•
Regeneration
When a large load inertia is operated at a high speed, the power supply
voltage may increase by the regenerative energy generated, causing an
alarm of overvoltage to generate. This may result in damage to the driver, so
reconsider the operating condition so as not to generate the regenerative
voltage.
Notes when the connection cable is used
Note the following points when our cable is used.
•
When bending the cable
Do not excessively bend the cable. Applying stress on the cable may cause
poor contact or disconnection, leading to malfunction or heat generation.
Do not bend excessively
•
How to fix the cable
Fix the cable near the connector to prevent stress due to the bending of cable
or the cable self-weight from being applied to the connector part. Also, do
not excessively bend the cable near the connection part of the connector.
Applying stress on the cable may cause poor contact or disconnection,
leading to malfunction or heat generation.
