Precautions for use
3 Precautions for use
This chapter explains the restrictions and other items you should take heed of when using the BLE Series.
 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 p.5
and p.24 for the selection of appropriate protective devices.
 Do not perform gravitational operation
With the BLE Series, any operation in which the motor output shaft is turned (gravitational operation) will disable the
motor speed control. In addition, a gravitational operation will cause the driver’s primary inverter voltage to exceed
the allowable value, thereby triggering a protection function and causing the motor to stop spontaneously. When the
motor stops, the load may drop.
 Do not use a solid-state relay (SSR) to turn on/o the power
A circuit that turns on/o the power via a solid-state relay (SSR) may damage the motor and driver.
 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.
 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. Oil leakage may lead to problems in the customer’s
equipment or products.
 Apply grease on the output shaft of 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.
 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 eect 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 oering resistance against high
frequency:
Mitsubishi Electric Corporation: NV series

6
Precautions for use
 Noise elimination measures
Provide the following noise elimination measures to prevent a motor or driver malfunction caused by external noise.
zWiring the motor
Use connection cable (supplied or sold separately) when extending the wiring distance between the motor and driver.
zWiring the I/O signal cable
•Minimize the wiring length of the I/O signal cable.
•Provide a minimum clearance of 100 mm (4 in.) between the I/O signal cable and any inductive load such as an
electromagnetic relay or any power line (power cable, motor cable, etc.). Do not place the I/O signal cable and a
power line in the same duct or pipe or bundle them together.
•For more eective elimination of noise, use a shielded I/O signal cable or attach ferrite cores if a non-shielded cable is
used.
zConnecting a mains lter for power line
•Connect a mains lter to the AC power input part of the driver to prevent external noise from reaching the driver via
the power line.
•Provide a ground connection from the mains lter ground terminal using a cable of AWG18 to 14 (0.75 to 2.0 mm2).
•Be sure to ground both ends of the shielded cable used for the mains lter.

 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.
 Use connection cable (supplied or sold separately) when extending the wiring distance
between the motor and driver

Note
•Do not forcibly assemble the motor and hollow shaft at gearhead. Also, do not let metal objects or other
foreign matter enter the hollow shaft at gearhead.
The pinion of the motor output shaft or the hollow shaft at gearhead itself may be damaged, resulting in
noise or shorter service life.
•Do not allow dust to attach to the pilot sections of the motor and hollow shaft at gearhead. Also,
assemble the motor carefully by not pinching the O-ring at the motor's pilot section. If the O-ring is
pinched, the coupling strength will drop and grease may leak from the hollow shaft at gearhead.
