Rated. / 5. Based on customer reviews
The overload rating for the drive determines the starting and accelerating characteristics of the motor. Expect lower torque
than when running from line power. To achieve a higher starting torque, use a larger drive or a drive and motor with larger
capacity.
Emergency Stop
During a drive fault condition, the output shuts off but the motor does not stop immediately. A mechanical brake may be
required when it is necessary to stop the motor faster than the ability of the Fast Stop function of the drive.
Repetitive Starting/Stopping
Laundry machines, punching presses, and other applications with frequent starts and stops often approach 150% of their rated
output current values. Heat stress generated from repetitive high current will shorten the life span of the IGBTs. The expected
life span of the IGBTs is about 8 million start and stop cycles with a 4 kHz carrier frequency and a 150% peak current.
Run only one motor from each drive when using vector control. It is not possible to run more than one motor from one drive
with vector control.
n
Carrier Frequency Derating
Reduce the rated output current of the drive when increasing the carrier frequency above the factory default setting. Refer
to Rated Current Depending on Carrier Frequency on page 249 for details.
n
Installation
Enclosure Panels
Keep the drive in a clean environment by installing the drive in an enclosure panel. Be sure to leave the required space between
drives to provide for cooling, and take proper measures so the ambient temperature remains within allowable limits and keep
flammable materials away from the drive. Yaskawa offers protective designs for drives that must be used in areas subjected
to oil mist and excessive vibration. Contact Yaskawa or your Yaskawa agent for details.
Installation Direction
NOTICE: Install the drive upright as specified in the manual. Refer to Mechanical Installation on page 42 for more information on
installation. Failure to comply may damage the drive due to improper cooling.
n
Settings
Motor Code
When using a permanent magnet motor, set the proper motor code to parameter E5-01 before performing a trial run.
Upper Limits
NOTICE: The drive is capable of running the motor up to 400 Hz. Be sure to set the upper limit for the frequency of the drive to prevent the
possible danger of accidentally operating equipment at higher than rated speed. The default setting for the maximum output frequency is
60 Hz.
DC Injection Braking
NOTICE: Excessive current during DC Injection Braking and excessive duration of DC Injection Braking can cause motor overheat.
Acceleration/Deceleration Times
Acceleration and deceleration times are affected by the amount of torque generated by the motor, the load torque, and the
moment of inertia. Set a longer accel/decel time when Stall Prevention is enabled. The accel/decel times are lengthened for
as long as the Stall Prevention function is in operation. Use a larger drive and motor for faster acceleration and deceleration.
n
General Handling
Wiring Check
NOTICE: Be sure to perform a final check of all sequence wiring and other connections before turning on the power and also check for short
circuits on the control terminals, which may damage the drive.
Selecting a Circuit Breaker or Circuit Interrupter
Yaskawa recommends installing a Ground Fault Circuit Interrupter (GFCI) to the power supply side. The GFCI should be
designed for use with AC drives (e.g., Type B according to IEC/EN 60755).
Select a Molded Case Circuit Breaker (MCCB) or GFCI with a rated current 1.5 to 2 times higher than the drive rated current
to avoid nuisance trips caused by harmonics in the drive input current. Refer to Installing a Molded Case Circuit Breaker
(MCCB) or Ground Fault Circuit Interrupter (GFCI) on page 238 for more information.
Magnetic Contactor Installation
WARNING! Fire Hazard. Shut off the drive with a magnetic contactor (MC) when a fault occurs in any external equipment such as braking
resistors. Refer to Installing a Magnetic Contactor at the Power Supply Side on page 239. Failure to comply may cause resistor
overheating, fire, and injury to personnel.
