Notes on braking
The brake circuit must be operated individually due to its required power supply. See page 34 for more
information.
Standard products are shipped with the brake lead wire screwed together with the motor lead wire. The
brake lead wire should be unscrewed and connected individually.
The frequency should be 60Hz (1800r/min) or lower during braking. Braking at high speed range over 60Hz
may cause mechanical damages, and heating and wear on lining. Make sure to operate at 60Hz or lower
frequency.
・
Using a 400V class motor for the inverter drive
Devices with a 400V class motor are available for made to order. With a 400V class motor, dielectric
breakdown may occur due to high voltage surges (microsurges) generated from the inverter switching. As a
result, measures against microsurges are generally required for such motors. Tsubaki 400V class of motor
comes standard with micro surge protection. However, with levels in excess of 1200V, a suppression filter or
reactor should be installed on the inverter side.
・
Other points to note
 Compared with standard power supplies; greater increases in temperature, noise, and vibration should
be expected when using an inverter drive.
 To protect the motor from overheating, use an electronic thermal mechanism configured for
general-purpose motor characteristics, or use a thermal relay or other device between the inverter and
the motor.
 When using at a base frequency of 50Hz, set the output torque to 0.8 times that in the chart above.
(with a 0.2kW or 0.4kW motor only)
 0.2kW and 0.4kW inverter motors are also available.

Connection
1. Wiring
Wiring should be performed in accordance with electrical equipment technical standards, indoor wiring
regulations, and regulations set forth by the electrical company. Be aware of significant voltage drops
caused by long wiring distances.
2. Ground
Ground the motor to prevent leaks from deteriorating insulation. Installing a ground fault interrupter will
provide an additional level of safety.
3. Always use a power source as printed on the nameplate.
