Applications with Specialized Motors
Multi-Pole Motor
Because the rated current will differ from a standard motor, be sure to check the maximum current when selecting a drive.
Always stop the motor before switching between the number of motor poles. If a regen overvoltage (oV) fault occurs or if
overcurrent protection (oC) is triggered, the motor will coast to stop.
Submersible Motor
Because motor rated current is greater than a standard motor, select the drive capacity accordingly. Be sure to use a large
enough gauge motor cable to avoid decreasing the maximum torque level on account of voltage drop caused by a long motor
cable.
i.3 Application Precautions
YASKAWA ELECTRIC SIEP C710606 18E YASKAWA AC Drive – V1000 Technical Manual 21
Explosion-Proof Motor
Both the motor and drive need to be tested together to be certified as explosion-proof. The drive is not designed for explosion
proof areas.
Furthermore, if an encoder is attached to an explosion-proof motor make sure the encoder is also explosion-proof. Use an
insulating signal converter for connecting the encoder signal lines to the drives speed feedback option card.
Geared Motor
To avoid gear damage when operating at low speeds or very high speeds, make sure that both the gear and lubricant are rated
for the desired speed range. Consult with the manufacturer for applications that require operation outside the rated speed range
of the motor or gear box.
Single-Phase Motor
Variable speed AC drives are not designed for operation with single phase motors. Using capacitors to start the motor causes
excessive current to flow and can damage drive components. A split-phase start or a repulsion start can end up burning out
the starter coils because the internal centrifugal switch is not activated. The drive is for use with 3-phase motors only.
Motor with Brake
Caution should be taken when using a drive to operate a motor with a built-in holding brake. If the brake is connected to the
output side of the drive, it may not release at start due to low voltage levels. A separate power supply should be installed for
the motor brake. Motors with a built-in brake tend to generate a fair amount of noise when running at low speeds.
n Power Driven Machinery (decelerators, belts, chains, etc.)
Continuous operation at low speeds wears on the lubricating material used in gear box type systems to accelerate and decelerate
power driven machinery. Caution should also be taken when operating at speeds above the rated machine speed due to noise
and shortened performance life.
