Precautions for use
3 Precautions for use
This chapter covers limitations and requirements the user should consider when using the product.
Be sure to match the output power of the driver with that of the motor when using.
zDo not perform gravitational operation (vertical drive).
If the
load side, the inverter voltage of the driver will exceed the permissible value, and the alarm function will be activated to
cause the motor to coast to a stop. If this happens, there is a possibility that the load will drop.
zGrease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental
contamination resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively,
install an oil pan or other device to prevent damage resulting from contamination. Grease leakage may lead to problems
in the user’s equipment or products.
zApply grease to the hollow output shaft of a hollow shaft at gearhead.
Apply grease (molybdenum disulde grease, etc.) on the surface of the load shaft and the inner walls of the hollow
output shaft to prevent seizure.
zDo not conduct the insulation resistance measurement or dielectric strength test with the motor and driver
connected.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver connected may
result in damage to the product.
Series is used in operation (i.e. gravitational operation) in which the motor output shaft is turned from the
BLH
zNoise elimination measures
Refer to p.13 for the noise elimination measures.
zNote on connecting a power supply whose positive terminal is grounded
The USB connector on the driver is 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.
zNotes about when saving the data to the non-volatile memory
Do not turn o the 24 VDC power supply while writing the data to the non-volatile memory, and also do not turn o
within 5 seconds after the completion of writing the data. Doing so may abort writing the data and cause a EEPROM
error alarm to generate.
The non-volatile memory can be rewritten approximately 100,000 times.

These signals are used to operate the motor.
The motor rotates according to the acceleration time when both the
START/STOP input and the RUN/BRAKE input are turned ON.
If the START/STOP input is turned OFF, the motor stops according to the
deceleration time. If the RUN/BRAKE input is turned OFF, the motor stops
instantaneously.
This signal is used to change the motor rotation direction.
The motor rotates in the forward direction when the signal is turned ON.
The operation data number can be selected based on a combination of
ON-OFF status of the M0 and M1 inputs.
This signal is used to reset the alarm.
(The alarm will be reset at the ON edge of the input.)
These terminals are used when the rotation speed or torque limiting
value is externally set using an external analog setting device (external
*3
potentiometer or external DC voltage).
This is a signal to output an alarm status.
It is turned OFF when an alarm is generated. (Normally closed)
This is a signal to output information of the motor rotation direction.
(It is turned ON when the motor rotates in the forward direction.)
