Precautions for use
−6−
3 Precautions for use
This chapter explains the restrictions and other items you should take heed of when using the BLE Series standard
type.
z Connect protective devices to the power line
Connect a circuit breaker or earth leakage breaker to the driver’s power line to protect the primary circuit. If an
earth leakage breaker is to be installed, use one incorporating high-frequency noise elimination measures. Refer to
“Preventing leakage current” below for the selection of protective devices.
z Use an electromagnetic brake type for an application involving vertical travel
When the motor is used in an application involving vertical travel, use an electromagnetic brake type to hold the load
in position.
z Do not use a solid-state relay (SSR) to turn on/off the power
A circuit that turns on/off the power via a solid-state relay (SSR) may damage the motor and driver.
z Conduct the insulation resistance measurement or withstand voltage test separately on the
motor and the driver
Conducting the insulation resistance measurement or withstand voltage test with the motor and driver connected may
result in injury or damage to the product.
z Grease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental damage
resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively, install an oil
pan or other device to prevent leakage from causing further damage. Grease leakage may lead to problems in the
customer’s equipment or products.
z Apply grease to the output shaft of a hollow shaft at gearhead
If you are using a hollow shaft at gearhead, apply grease (molybdenum disulde grease, etc.) on the surface of the
load shaft and inner walls of the hollow output shaft to prevent seizure.
z Preventing leakage current
Stray capacitance exists between the driver’s current-carrying line and other current-carrying lines, the earth and the
motor, respectively. A high-frequency current may leak out through such capacitance, having a detrimental effect on
the surrounding equipment. The actual leakage current depends on the driver’s switching frequency, the length of
wiring between the driver and motor, and so on.
When connecting an earth leakage breaker, use one of the following products offering resistance against high
frequency current:
Mitsubishi Electric Corporation: NV series
z Noise elimination measures
Provide noise elimination measures to prevent a motor or driver malfunction caused by external noise.
For more effective elimination of noise, use a shielded I/O signal cable or attach ferrite cores if a non-shielded cable
is used. Refer to p.23 for the noise elimination measures.
z Note on connecting a power supply whose positive terminal is grounded
The communication connector (CN3) and I/O signal connector (CN5) are not 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 PC to short, damaging both.
z Use a connection cable (supplied or accessory) when extending the wiring distance between the
motor and driver
z When using the motor in operation such as vertical drive (gravitational operation) or a large
inertial load drive, use an accessory regeneration unit (sold separately).
The driver may be damaged if the regeneration energy generated during vertical drive (gravitational operation) or
sudden starting/stopping of a large inertial load exceeds the allowable limit that can be absorbed by the driver.
The accessory regeneration unit (sold separately) is designed to discharge the regenerated energy, thereby protecting
the driver.
