A1000 Drive - Options
This array of Power-related options are available for Yaskawa AC drives as shown. Some may be factory-mounted within a drive enclosure, others may be separately mounted.

More Information
|
|---|---|
| 24VDC Control Power Unit...This option provides board-level component voltages for the A1000 drive when provided with 24VDC from an external, customer-supplied source. It is used to maintain both drive control power and network communications (when utilized). Option kit for customer mounting. | |
| Reactor...Used on either the input or output of a drive to reduce the effect of line-side or load-side transients. These 3-phase reactors are available in a NEMA 1 enclosure for field installation, or factory installed in a Configured package. | |
| DC Bus Reactor...Used in place of an input reactor to improve power factor. Helps attenuate distortion back to the line and to reduce DC bus ripple current. Available in a NEMA 1 enclosure for field installation, or factory installed in a Configured package. | |
| EMC Filters...Used on the input of the drive to attenuate possible drive-generated noise. Filters should always be mounted as close to the drive a possible. These filters meet the requirements for CE. | |
| Dynamic Braking 10% Duty...Assists the drive to periodically decelerate a load without overvoltage trips. Dynamic braking consists of at least one transistor and at least one resistor, and is sized for rated motor horsepower. The braking transistor may be included in the standard drive. The resistors are sized for a 10% duty cycle (10 seconds maximum on-time of every 100 seconds), and will provide approximately 150% braking torque. Ten percent dynamic braking is not typically used for "hold-back" type applications such as unwinders, hoists, or downhill conveyors. | |
| Dynamic Braking 3% Duty...Are rated for 3% duty cycle over a 100-second interval. Approximate braking torque for each rating is listed. These resistors are designed for separate panel mounting. | |
| Line Regeneration Converters...Yaskawa offers two line-regeneration products, that can provide braking torque in applications that have large overhauling loads or make frequent stops such as elevators, centrifuges, test stands, and winders. Line regeneration can result in significantly reduced operation costs in these types of machinery by "re-cycling" the excess power back to the power grid. The D1000 is a high performance converter with a PWM sinusoidal waveform with very low harmonic distortion (approximately 5% THD) and is designed to meet IEEE-519 requirements. The D1000 is wired in series between the drive and the incoming line and therefore must have an equal or larger current rating than the drive. The DC5 handles both motoring and regenerative power from the drive. The R1000 unit is lower cost with a 6-step output waveform that does not provide IEEE-519 compliant power and can be sized based on the application, from continuous to intermittent. The R1000 is wired in parallel to the drive and only handles regeneration power. The drive handles motoring power through its own diode bridge. |
