Yaskawa America offers the Z1000 family of variable-speed drives.
The Z1000 family of variable-speed drives from Yaskawa America Inc. is designed for building automation applications such as fans, pumps, and cooling towers through 500 hp. Its features begin with an easy-to-read LCD operator with hand-off-auto functions. An internal real-time clock with time/date stamping and timer controls allows for speed variations without the need for external controls. A built-in 5% line impedance reduces input harmonic distortion, while a 5 kHz carrier frequency with dynamic noise control provides quiet motor operation. An on-board EMI/RFI filter compliant with IEC 61800-3 minimizes interference of surrounding equipment. All Z1000 drives also feature embedded BACnet communications (BTL certified), along with Modbus/Memobus. Applications macros are available to facilitate quick and easy setup.
