Yaskawa
Yaskawa Electric America provides Industrial Control and Automation products to markets in the Americas. Yaskawa is the world’s largest manufacturer of ac drives and motion control products, including adjustable frequency drives servo amplifiers, servomotors, machine controllers, and motion controllers.
Commercial HVAC Drives 1/2 thru 500 Horsepower
Yaskawa is the largest global variable frequency drives manufacturer with over 30 years of Building Automation System (BAS) and HVAC experience. Our variable frequency drives are designed for HVAC applications, which include air handlers, cooling towers and pumps, by combining reduced size and cost with step changes in performance and quality. The drive features for Building Automation Systems include extensive parameter selection which simplifies management of BAS applications for energy efficiency and closed loop control, industry-standard Hand/Off/Auto functionality, an internal PI controller and a Sleep function. Because all variable frequency drives (VFDs) are rigorously tested, Yaskawa ensures that quality and reliability are designed and built in.
E7 Drives have embedded Metasys® and APOGEE™ Communications. BACnet® and LonWorks® are optional.

Product Offerings
E7 Drive
The E7 Drive is
designed exclusively for Commercial HVAC applications. All features are designed
for this purpose, including Building Automation communications. Metasys N2,
APOGEE FLN and Modbus are embedded. EtherNet/IP, Modbus TCP/IP and LonWorks are
plug-in options. The drive is plenum rated for variable torque applications.
Anti-windmilling, motor preheat, energy-savings, and PI setpoint control are
standard. Many options are available.
E7C Configured Drive
The E7C
Configured package provides an E7 drive in a NEMA 1 or NEMA 12 enclosure, with
space for several commonly used options, such as reactors, RFI filters, circuit
breakers, etc.
The E7C has embedded communications for the popular building automation protocols, Johnson Controls Metasys® N2 and Siemens APOGEE™FLN, as well as Modbus. Optional LonWorks®, EtherNet/IP and Modbus TCP/IP interface cards are available.
E7N Narrow Bypass Package
The E7N Narrow
Bypass package is a 2-contactor style bypass with HOA touchpad control, allowing
motor operation from either the drive or across the line. This allows continued
operation even if the E7 drive is disabled by fault or intention. Drive
maintenance must be delayed until line power can be removed.
The E7N is a versatile narrow enclosure that meets the space requirements of end users and OEMs, yet has the flexibility to meet the varying requirements of specifying engineers and HVAC designers.
E7L Bypass Package
The E7L Bypass
package is a 2-contactor bypass with HOA touchpad control, allowing motor
operation from either the drive or across the line. This allows continued
operation even if the E7 drive is disabled, by fault or intention. Drive
maintenance must be delayed until line power can be removed. The E7 and E7L
Bypass have been designed for flexibility in providing the features and options
commonly demanded by HVAC designers.
E7B Bypass Package
The E7B Bypass
package is a 3-contactor style bypass, allowing motor operation from either the
drive or across the line. This facilitates drive maintenance while the motor
continues to operate. The E7B Bypass is designed for flexibility in providing
the features and options commonly demanded by facility designers.
E7E Engineered Package
Custom
Engineered Drives require additional engineering time and are supported through
custom engineered drawings and documentation. The E7E can provide the features
and options demanded by facility engineers. If the standard features and
standard options of the E7, E7C, E7L or E7B do not totally fulfill the
specification requirements, the Custom Engineered E7E will.
