Yaskawa's Z1000 Family of Drives
This family of drives is comprised of the Z1000 variable speed drive as well as the Z1000 Bypass Package. Both are designed for commercial HVAC applications.
The Z1000 Variable Speed Drive 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, a built-in 5% line impedance to reduce input harmonic distortion, a 5 kHz carrier frequency with dynamic noise control for quiet motor operation,and an on-board EMI/RFI filter compliant with IEC 61800-3. All Z1000 drives also feature embedded BACnet communications (BTL certified), along with Modbus/Memobus.
The Z1000 Bypass Package is optimized with an Intelligent Bypass and advance BAS interface. The Intelligent Bypass, when enabled, can transfer the motor across the line when the application requires 60Hz. It is available in NEMA 1 models that include ratings of 1 to 150 HP (208V) and 1 to 500 HP (480V).
